What Are The Differences Between Kawasaki FR And FS Engines?

Knowing the differences between Kawasaki FR and FS engines will help you choose the best lawn mower for your garden. This is why we are going for a comparison session to learn about these two series in-depth level. Let’s move on!

Both Are 4-Cycle Engine

Both Kawasaki FR and FS engines have four-stroke engines. Hence, for every rotation, the piston makes a pressurized stroke followed by an exhaust stroke. As a result, you will notice one spark plug fire per rotation or once every four strokes.

Cast Iron Cylinder Liners Vs. Cast Iron Liners

The Kawasaki FR series has cast-iron liners, while the Kawasaki FS series cast iron cylinder liners.

A multi-cylinder block includes cylinder liners, which is a vital part of it. The working space of a piston and its sliding surface is determined and shared by these two components.

Special alloy cast iron is used to make the cylinder liners, and you will find this material is more resistant to abrasion than gray cast iron with flake graphite.

Though both series have cast-iron liners, the Kawasaki FS series is more efficient than cylinder liners.

Washout Port

The Kawasaki FS series engines have an integrated cleanout port absent in the Kawasaki FR series engines.

So, what value will you get for having this integrated cleanout port? Most garden experts recommend cleaning lawnmowers after each use to ensure the possible life expectancy and effective cleaning performance.

Cleaning a mower deck is easier and quicker with an integrated cleanout port. Hence, you are getting an extra benefit for using the Kawasaki FS series under this point.

90 V-twin Overhead V-valve Vs. OHV V-valve Technology

The Kawasaki FR Series engines are mainly 90 V-twin engines. This type of engine covers less space, allowing other components to accommodate this extra space.

On the other hand, the Kawasaki FS series include OHV V-valve technology, which has excellent benefit to supply air quickly and efficiently.

Pressurized Lubrication System

Both Kawasaki FR and FS engines have a pressurized lubrication system, meaning the oil is positively introduced into the bearings.

A pressure pump accurately distributes oil to significant areas of the pump by the pressure lubrication system.

Most garden experts said Splash lubrication does not perform as well as pressure lubrication. Therefore, you are getting the same benefit for using both series engines under this point.

High Pressure Die Cast Aluminum Block And Heads

The engines of the FS series are made with high pressure die casting production system to boost their production speed. In addition, the outer surface of this machine is heat resistant, making them stronger and sturdier.

Die casting ensures good dimensional stability while also maintaining tight tolerances. In addition, its aluminum block and heads make the engine lightweight. Hence, it gives you more flexibility and portability to cut grasses.

On the contrary, there is no such high-pressure die-cast aluminum block and heads used for engines of the FR series. Hence, the machines of the FS series stand in a higher position under this point.

High Energy Spark Ignition

The engines of the FR series feature a high-energy ignition system. This system is mainly intended for the forthright spark ignition of gas or oil igniters.

The main advantage of having high-energy spark ignition has minimal misfires. It is because this spark plug is designed to provide a constant, high voltage spark throughout the lifespan of the engine.

On the contrary, you will not get such a type of ignition system in the FS series. Therefore, the engines of the FR series are winners regarding this point.

Dual Element Air Filtering System

The engines of the FS series come with dual element air filtering system. It means the engines have two kinds of filtering media. Air will pass through these two filters to ensure dust or dirt-free air for machines.

Though the engines of the FR series have a decent air filtering system, they are not as effective as the FS series. As a result, you may want to consider the FS series if you prefer a more effective air filtering system.

Made For Different Purposes

The Kawasaki FR and FS engines are not made for the same purposes. If you desire to convert your lawn to look like a professional, the FS Series engines are a better option.

However, most gardeners will not need this as you will not mow your lawn or grass every day. This is a better choice for people or companies who provide Lawn Mowing Services.

The FS series has many extra features, which you will not find in the FR series. You will be able to do professional tasks more effectively and quickly with these series.

On the other hand, the Kawasaki FR series is best suitable for a household garden. They have solid components to make your grass cutting easy and hassle-free. Most household gardeners are satisfied with the model.


Professional machines have obviously higher than residential machines. After all, professional engines can take care of heavy works for a long time. That’s why the Kawasaki FS series engines have a higher price than the FR series.

Let get an overview to learn the difference between Kawasaki FR and FS engines:

Which Engine Should I Choose for my Zero Turn Mower?

Not all mowers are built equally. So many options are available in the market; which engine should I choose for my zero-turn mower? Right?

Kawasaki FX, Briggs Stratton Vanguard, TORO ZX, and KOHLER Command Pro are some high-end models that will never disappoint you.

However, our requirements and personal preference vary. That’s why you want to pick a model that seems most convenient for you finally. Let’s know some crucial points to find the best zero turn mower:

Zero Turn Mower Engine

When you want to have a reliable and consistent performance from a mower with fast speed, choose a mower that has a large engine size and more horsepower.

But before that, you want to decide whether you will use this mower for commercial or residential purposes. You don’t need excessive horsepower if you utilize it only for your individual goals.

If you have a large garden or managing a small lawn care business, Spartan RT HD or Kohler 7000 Professional Series. If you want a more powerful mower for your huge business, you can choose the Vanguard EFI/37 HP engine option.

How Much Fuel The Engine Can Hold?

For residential purposes, small-sized fuel capacity is okay. Most times, with 5-gallon fuels, they can cover their full gardens. Your machine will run smoothly while keeping the gasoline tired-free.

However, medium or large-sized fuel capacity is essential if you have huge yards or run a lawn care business. After all, you don’t want to fill up fuel repeatedly in the middle of the cutting grass. They will at least need 9-10 gallon fuels to cut grass without a break.

Zero Turn Mower Deck Size

When looking for the best engine for zero-turn mowers, deck size is a crucial factor you don’t want to miss out on.

On average, most mowers come with 48-72 inches deck sizes. However, you may discover several options among them.

But the query is, what is the ideal deck size for lawnmowers?

When you want more portability and flexibility, small-sized decks will be a better option. You can run on the machine smoothly even in a limited space or a small fence gate. On the other hand, a large deck size is convenient for extended coverage, especially commercial purposes.

Quick Adjustable Cutting Height

You may sometimes need to change the mower cutting height to deal with the craggy ground, unstable areas, or massive tree roots. The quicker you can adjust your mower cutting height, the more convenient it is to use.

Comfortability While Cutting Grass

The user experience for cutting grass with zero-turn mowers should be pleasurable and comfortable. In that case, how you feel while sitting on the seat, how much back support it provides, and how problem-free it is to control the mower.

You should check out their ergonomic design, quick response braking system, safe riding, and many additional features. In some cases, you may not be able to find a model with all the features you desire.

Are you still wondering about this query: which engine should I choose for my zero-turn mower? You just need to consider these essential factors to find the best machine for a zero-turn mower.

Is the engine the most important part of selecting a good Zero Turn?

Many new gardeners often asked this question: is the engine the most important part of selecting a good zero turn?

A lawnmower cannot be operated without an engine. Nevertheless, it isn’t the only factor that matters. You want to check other essential components and functions to discover the best zero-turn mower.

For a good zero-turn mower, you should look at several other things.

Serial No. Important Factors

First of all, you want to ensure that all lawnmower parts are made from high-quality components for long-lasting durability. In addition, the deck should be strong enough to endure high impacts and rust and can take heavy loads for years.

Quality should be assured for the mower frame too so that it doesn’t distort or break easily. However, everything is not possible to measure by numbers.

For instance, how effectively the overall weight of the machine is distributed throughout the engine to ensure maximum traction, flexibility, and uneven areas stability?

Apart from that, how efficiently can your lawnmower cut most grass? Does it face difficulty to cut hard-type grass?

all-in-one, guide, kohler, kawasaki, engine, which

Premium-priced lawnmowers are made from high-quality components. However, many popular brands only FOCUS on few parts of the machine instead of each part.

Though you are paying a high price and expecting the best quality for each part, you often may not get your desired results. Nevertheless, you indeed need to spend a great deal of money to purchase a decent lawnmower. But make sure all components are high-quality to get the best user experience.

Is the Kawasaki FS Series Engine Inferior to the FX?

Kawasaki is not a new brand in the mower market. They have been dominating the market for several decades. However, according to old users of mowers from this brand, their old models were far better than the recent models. They could easily use them for around 15-20 years without showing any sign of quality deterioration and engine problems.

Is the Kawasaki FS series engine inferior to the FX?

Both the Kawasaki FS series and FX series have high-end models. However, the Kawasaki FX series have an industrial air filtration setup, which gives a bonus point for buying a particular model from this series. For the Kawasaki FS series, you will have to clean out the filter regularly to prevent crawling up. This is the main benefit of these two series.

On the other hand, the Kawasaki FS series allows you to easily cut any small-size pine trees and other unelevated branches.

Didn’t I just see in another thread that you use turf tracers?? Don’t you like the Kawasaki engine on those mowers?

Though the company claims their machines can be run up to 5000 hours, their performance is not as exact as after running 1000 hours.

People are questioning their built-in quality though they are reputed brands. There is a common saying that low-quality components have been used to boost profit margins. That’s why some of them are nowadays buying other brand lawnmowers for running a ton of hours.

What Is The Best Engine For A Zero Turn Mower?

We have already mentioned above some essential points, which you should consider to find the best engine for a zero-turn mower.

What is the best engine for a zero-turn mower?

Kwasaki FS is the best engine for a zero-turn mower according to most of the experts. Choosing the best engine for a zero-turn mower requires some handwork and considerations. After all, you want to get the best value for the money.

How Much Price You Are Ready To Spend?

When you think of buying a zero-turn mower, you have most probably ready to spend approximately 5,000 or more. High-priced options mean you will get better quality and with extra features and functions.

However, as we have already noted, don’t blindly purchase a zero-turn mower just because it comes from a reputed brand. Instead, look for every nut and bolt to judge their quality and user-friendliness to make an informed purchasing decision.

How Much Motor Power Do You Need?

How much motor power you will need depends on which type of grass and mown you will cut.

Try to choose at least 20 horsepower motors for consistent and efficient cutting. Mowers with less than 20 horsepower will not help you cut grass and lawn evenly. Also, they will wear out or leave excessive spots on the blades.

Most people use zero-turn mowers for three purposes: residential, semi-professional, or commercial. Here we are mentioning through a table what should be the motor power for zero-turn mowers.

Does The Zero Turn Mower Have A Hydrostatic Transmission?

During hydraulic tranny operation, fluid is used to allow gear shifts and power transmission. Even when you are cutting grasses in the most challenging conditions, Hydrostatic models can show reliable performance.

Plus, using them for extended periods doesn’t cause them to burn out. You will have the efficiency on the machine to make out the best performance from it.

How Weighty Is The Zero Turn Mower?

A zero-turn mower can be as heavy as 700-lbs. As the machine is pretty heavy, cleaning the cutting deck’s underside will require a jack.

However, you can clean the cutting deck of small-sized mowers from its side by turning them.

How Much Safe The Zero Turn Mower?

Every machine should have safety features, so does a zero-turn mower. Different model has different safety features such as kill switches, automatic chokes, and so forth.

Some models may have more than one safety feature. Don’t forget to check out this point, especially if you will buy a zero-turn mower for the first time.

How Good Are The Machine Tires?

Like go-kart models, most zero-turn mowers have air-filled tires. One of the critical jobs of tires is providing tractions.

Achieving precise cutting results is not possible, especially for wet grass, unless the tires have a lot of treads.

How Efficiently Can You Control The Mower?

No matter how good the mower is, you can’t achieve your desired result if you can’t control it properly.

Avoid choosing any zero-turn mower that is prone to operator fatigue. Instead, choose a model that allows you to control the machine comfortably with better grips and levers. Having levers with adjustable settings gives you extra benefits while saving your time too.

Now you have become knowledgeable enough about how to choose the best engine for a zero-turn mower. Allow us to recommend some top-notch quality zero-turn mowers from the market.

Why Should You Choose Kawasaki Engines Over Kohler Engines?

No doubt, the Kohler brand already gained immense popularity in the market. But many garden experts still rank Kawasaki Engines one step ahead over Kohler engines due to consistent quality.

What’s more, Kohler engines are relatively heavy compared to Kawasaki Engines, making them less portable and flexible.

As Kohler engines don’t perform as consistently as Kawasaki Engines do, you will bear higher maintenance costs for using Kohler engines throughout its life span.

However, there is no way you can still overlook Kohler engines. If they are inferior, people won’t buy their engines. So, Kawasaki and Kohler are both excellent choices no matter the reason for replacing an engine.

Wrapping Up

Kohler Vs Kawasaki Mower Engine: A Chart Of Comparison

Before we assess both the engines on different factors, you must know that the major point of difference between a Kohler and a Kawasaki engine lies in the way they have been constructed.

A Kohler engine has its main components made up of plastic whereas the Kawasaki engine uses metal for its parts.

Both the engines have a different set of pros and cons. So, take a look at this quick table of comparison to learn what factors you should be considering while choosing a Kohler vs Kawasaki engine.

Points of Comparison Kawasaki Kohler
Engine Commercial engine with carburetor Fuel-powered engine
Element of construction Metal Plastic components
Cost Very costly Affordable
Fuel Efficiency Less efficient fuel system Better fuel efficiency than Kawasaki

Warranty 36 months warranty Ranges from one to three years depending on the model

Now, let me explain these parameters of judgement to you so that you are well-versed with all the special features and limitations these engines have.

Engine’s Horsepower:

If you compare a Kohler vs Kawasaki engine as per the horsepower it offers, it is the Kawasaki engine that is superior, following the SAE J2723 guidelines.

These guidelines dictate that the engine is providing the users 98% of the horsepower it claims.

  • A Kawasaki engine has almost 98-99% more horsepower which makes it a perfect choice for any kind of lawn task. It also has more speed due to the more horsepower it offers.
  • A 22 HP engine gives maximum power of 39.4 ft. lbs per 2200 rpm.
  • An engine with 36 rating gives maximum torque of 40.1 ft lbs per 2800 rpm.
  • An engine with 35 HP rating gives power up to 56 ft. lbs per 2800 rpm.

Time and again, both the Kohler vs Kawasaki engines have been compared and tested by legitimate engine testing bodies and it has been proven that the torque range goes higher as the horsepower increases!

In short, the more powerful the engine is, the more horsepower it has!

As for the Kohler engines, sadly, they do not have the best torque or horsepower in the market.

Winner : Kawasaki

Element of Construction;

As quoted above, the main difference in the Kohler and the Kawasaki engines is the element of their construction.

  • The Kohler engine has plastic parts whereas the Kawasaki engine’s body is metallic.
  • Since the Kohler engine has plastic parts, there is always a risk. Due to the heat emitted by the fuel, the plastic may start falling apart after a point of time and the components wear out.
  • Although this factor makes a Kohler engine less durable, there are a number of small-engine lawn mowers which use a Kohler engine, namely the Husqavarna, Cub Cadet, Dixon, Ariens etc. After a point of time, these mowers begin to develop engine issues due to the damaged engine components.
  • a Kawasaki engine has a metallic frame which saves the mowers that use a Kawasaki engine from the risk of engine issues.
  • A metallic body is more likely to sustain in the presence of the heat emitted by the fuel in the engine. These metallic engine parts require timely maintenance but at least there is no risk of incurring a decay or damage on them.

So, as far as the body of the engine is concerned, the Kawasaki engines are better.

Winner : Kawasaki


There is a notable difference in price between a Kohler and a Kawasaki engine. The reason is obvious: the plastic parts of the Kohler engine are cheaper than the metallic components of a Kawasaki engine.

The Kohler engines are cheaper than the Kawasaki engines.

I agree, the difference in the cost is considerable and it does matter! After all, who wouldn’t choose a mower which offers decent features at less price but there’s a catch!

No doubt, the small Kohler engine can suffice your lawn needs but it doesn’t offer the performance and durability that a Kawasaki engine offers. The Kawasaki engine truly justifies the high price with a powerful torque and superior performance.

Nonetheless, comparing the cost of a Kohler vs Kawasaki engine, the Kohler engine is more affordable.

Winner: Kohler

Engine’s Efficiency;

The efficiency of an engine depends on the fuel it uses.

  • The Kohler engine uses gasoline on most of its models.
  • On some of the models that do not have a carburetor, it also uses propane which is very fuel-efficient.
  • Kohler has the Command Pro EFI Engine which can help you save at least 600 every year as the fuel cost.

If a Kawasaki engine is compared in terms of efficiency-

If you compare the Kohler 7000 vs Kawasaki Fr, they differ mainly in their application. The Kohler 7000 engine series is mostly used for utility power appliances whereas the Kawasaki Fr is meant for outdoor purposes.

In short, both the Kohler and the Kawasaki engine have the EFI Technology but the Kohler engine is known to consume less fuel than a Kawasaki engine.

Winner : Kohler

Need for Maintenance ;

The guidelines for maintenance are different on a Kohler and a Kawasaki engine.

  • A Kawasaki engine has an open-loop control system.
  • As per this technology, there are less parts that need maintenance and you can just stick to the basic oil-change, filter-clean etc to suffice the regular maintenance needs.
  • Also, the Kawasaki recommends minimal need for regular maintenance.
  • A Kohler engine has a closed-loop system due to which there are more parts in the engine that require maintenance.
  • You would be changing the engine oil, the filters and other parts more regularly than a Kawasaki engine as Kohler stresses in maximizing the maintenance practices.

Hence, if as per maintenance if you ask me, is Kohler or Kawasaki engine better, this can be a point of stark difference! It is the Kawasaki engine which can give a free hand relatively as per maintenance is concerned and would go on for long without a frequent change in the engine oil and the cooling filters.

Winner: Kawasaki


It is only regular maintenance with which you can ensure the longevity of an engine! Regardless of the horsepower it has or the element of construction, every engine requires maintenance as the basic need.

Be it a Kohler engine or a Kawasaki, the more you take care of it, the longer it’s lifespan becomes! It is obvious that if the mower is used almost daily, the engine has more chances of wear-and-tears and thus, requires maintenance on a regular basis.

  • If maintained regularly, a Kawasaki engine easily lasts up to 3000 hours of mowing sessions. A user was in fact, able to sustain a Kaswaaki engine mower for as long as 15 years due to good maintenance practices.
  • A kohler engine, on the other hand, lasts for about 2000 hours if the engine has an air-cooling system. With regular maintenance, the Kohler engines too can last for almost 4000 hours.

So as far as the lifespan is concerned, it solely depends on how well and regularly you maintain the engine. The lifespan of both the Kohler and the Kawasaki engines depend on how well you maintain them!

Winner : It’s a tie !

Customer Support System;

The customer support system of both the Kohler and Kawasaki engine can be compared on the basis of how approachable and friendly the customer support team is and how soon they revert back to the reported issues.

  • Customer Service for Kawasaki is known to respond more to the emails that concern the warranty or any repair issue. They can be contacted via phone as well, from Monday to Friday but as per the reports, the approach remains ceremonial and explicit.
  • On the other hand, the Customer Support team of a Kohler engine is exceptionally approachable and friendly, in comparison to other brands when they’re contacted via phone. You can ring them up from Monday to Friday between 8 am to 5pm and they would be happy to help!

Hence, as for the customer support, it is Kohler that wins the gold star!

Winner: Kohler

Warranty Period;

There is a big noticeable difference if you compare the Kohler engine vs Kawasaki.

  • Most of the Kawasaki engine mowers are covered by a 36 months warranty. It means that during these 3 years, Kawasaki would take care of it.
  • If you are using any of the Husqvarna MZ54 mower or the Z254f, or say the Cub Cadet ZT1 50 mower and you face any issue, you can get them replaced by Kawasaki without paying any additional fee.

On the other hand, the warranty on the Kohler engines varies on different models.

  • The warranty of Kohler engines on residential models is more than on the commercial models.
  • The warranties by Kohler usually range from one to five years.
  • At the same time, the warranty of commercial models of Kohler mostly ranges from 90 days to 3 years. Additionally, this warranty period varies differently on different Kohler engines.

So, in the category of warranty, the Kawasaki engine takes the prize away!

Winner : Kawasaki

Final Thoughts

Based on the above mentioned factors, if I have to declare one as the winner, it is the Kawasaki engine.

There is no denying the fact that the Kohler engines have better fuel-efficiency and customer support. They are also affordable but the Kawasaki engines definitely have better horsepower, maintenance norms and a tougher build which goes a long way when you have to use the mower frequently.

So, make your choice after considering the above mentioned factors in detail but as a suggestion, do not compromise on the power of the engine for less money. After all, it is the engine which would keep the lawn mower mowing your lawn and money once spent well is never regretted !

Engine issues are bound to occur on lawn mowers after a period of time and they require regular maintenance. So, make a wise decision and always prefer durability and performance over affordability when it comes to machinery.

Kawasaki Engine Maintenance

Kawasaki recommends draining the fuel system if the engine is stored for more than 30 days.


Kawasaki recommends SAE 10W-40 for most operating conditions, but you may need a different oil for extreme heat or if you use your mower with snow clearing attachments. 20W-50 is recommended for temperatures over 104°F, and 5W-20 for temperatures below 32°F.

Check the engine oil level before each use. When checking the oil, the dipstick should be inserted into the filler neck, but not screwed in. Add oil if the level is below the “ADD” mark on the dipstick.

To change the oil, warm up the engine, and park the equipment on a level surface. Shut off the engine. Remove the drain plug directly below the oil filter.

To change the filter, drain the oil, then unscrew the filter by turning it counter-clockwise. Coat the seal on the new filter with new engine oil, then screw it onto the engine. Once it seats, turn the filter another ¾ turn to get a good seal.

The FR651V, FR691V, and FR730V all hold 1.9 quarts of oil with the filter installed. When replacing the oil filter, add 2.2 quarts of oil to top off both the crankcase and the filter. After changing the filter, run the engine for three minutes to circulate oil through the lubrication system. Shut off the engine, check for leaks around the filter, and check the oil level. Add more oil as needed.

The filter is behind a door on the top front of the engine. To clean the air filter, tap it against a hard surface. This loosens surface dirt and debris between the filter fins.

Spark Plugs

The plugs are next to the valve covers, labeled “OHV V-VALVE.” Unplug the spark plug caps, then unscrew the plugs using a socket.

Use a wire brush to remove carbon deposits. Gap the electrodes to 0.030 inches (0.75 mm.) When installing the plugs, thread them in by hand to avoid cross-threading. Tighten them to 16 ft-lbs.

Engine Cleaning

Check the rotary screen on top of the engine before each use, removing any grass or other debris.

To clean the cylinders and fins, remove the air filter. Next, remove the fan housing. It’s held on by bolts at the front and rear of the engine, and in line with the oil filter. Use a brush or dry rag to wipe away debris and dirt buildup from the engine, then install the shroud and air filter.

Fuel System and Storage

Kawasaki recommends using a stabilizer with fuel that will be in the engine for more than two weeks. Drain the fuel system if the engine will be stored for more than a month.

  • Clean the engine.
  • Close the fuel valve. Remove the sediment bowl directly below the valve.
  • Place a container under the valve.
  • Open the fuel valve. This will drain all of the fuel inside the engine aside from the carburetor. Once the system is empty, install the sediment bowl.
  • Start the engine and let it run until it stalls. This will burn off the remaining fuel inside the carburetor.
  • Once the engine is cool, remove the spark plugs and add one or two drops of engine oil to each cylinder. Turn the engine over a few times to circulate the oil.
  • Install the spark plugs. Lightly tug on the starter until you feel resistance. This positions the valve train so that the valves are closed, sealing the combustion chambers.

Kohler VS Kawasaki | Pros And Cons Of Each [2022 Update]

Gas-powered lawnmowers often use Kohler or Kawasaki engines. In fact, some of the most popular models available on the market right now use a Kawasaki engine or a Kohler engine.

With so many models available and different mowers using these engines, it can be hard to figure out which brand is better.

We’ve looked at both brands and different lawnmowers using these engines to help figure out once and for all in the debate of Kohler vs Kawasaki which brand is better.

Here’s a quick look at what we found and an in-depth summary of the pros and cons of each brand.

Main Differences Between Kawasaki And Kohler Engines

The three main differences between Kawasaki and Kohler Engines are their power, fuel efficiency, and reliability. Here’s how we felt each brand compared to each other in the following categories.


Kawasaki Critical Power Engines are SAE certified and adhere to SAE J2723. This standard designates that the engine has adhered to strict standards and that Kawasaki engines deliver at least 98% of their rated horsepower.

Kohler motors, on the other hand, are compliant with SAE J1940. This standard is for small engine types that power lawn, general utility equipment, and other small engine applications.

SAE J1940 states that the engine has a maximum of 1L of swept volume displacement, but holds no guarantees about horsepower ranges.

For that reason, we feel more comfortable with Kawasaki engines being more reliable regarding their advertised power.

Alternative Fuels

While both brands FOCUS on fuel efficiency, Kohler offers engines with alternative fuel sources.

You can purchase a Kohler engine that runs on either propane or natural gas to save on your fuel bill.

With the rising costs of gasoline and diesel, many are beginning to consider alternative sources of fuel, but only Kohler has engines that can burn alternative fuel sources currently.


While both brands are known for their reliability, the Kohler Courage engine is known to have fairly common problems.

Many people have reported that their Courage model engine has suffered from leaky gaskets or cracking after just 100 hours of operation.

Kawasaki engines are typically more reliable machines than a Kohler engine like the Courage model.


Kawasaki lawnmower engines are known to be long-lasting and are some of the most reliable engines on the market.

With that said, Kohler lawn mower engines are also known to be long-lasting. There’s no clear winner here when it comes to the lifespan of these engines.

Each brand can easily manufacture an engine that lasts for a thousand hours. Kawasaki lawnmower engines have been reported to last easily over a decade if taken care of.

Kohler Engine Pros

A Kohler engine is often way cheaper than a Kawasaki engine without sacrificing much. Cheaper engines will, in turn, make the lawn mower cheaper as well.

Kohler is also well known for its exceptional customer service. If you do have a problem, they’re there to help.

In a day and age where getting a good customer service rep is rare, this is definitely appreciated.

Kohler engines are also more common on the market when it comes to lawn care equipment and even other tools like powerwashers or tillers.

This means that mechanics will be more familiar with Kohler lawnmower engines, and there may be wider availability of spare parts on the market.

Kohler Engine Cons

While Kohler is reliable, we would’ve liked to have seen more from a well-known brand. Kawasaki engines have that SAE rating that shows they have the horsepower they advertise.

It would have been nice for Kohler to advertise the same rating on their engines.

We also wish they wouldn’t have had so many issues with their recent Courage model engine. That Kohler engine doesn’t have the best reputation among the lawn mowing community.

Regarding warranties in the Kohler vs Kawasaki debate, Kohler isn’t looking as good as Kawasaki. Kohler offers a lesser warranty on its products compared to Kawasaki.

Kawasaki Engine Pros

Kawasaki engines are famous for their reliability and power. With that SAE rating we previously mentioned above, Kawasaki has proven to consumers that they are trying to lead the way in the small engine market.

Lawnmowers with a Kawasaki engine are sure to perform better than other models on the market, thanks to Kawasaki’s innovation and tech.

Kawasaki engines also come with great warranties. You should get a general three-year warranty when you purchase a Kawasaki engine but check with the dealer or Kawasaki themselves before purchasing to make sure.

Kawasaki Engine Cons

Depending on the Kawasaki engine, it may be more expensive than other comparable engines on the market. If price is a factor, you may want to look at alternatives before making your final purchase.

When it comes to fuel efficiency, Kawasaki isn’t exactly leading the pack. While their Kawasaki mower engines are powerful, other motors from Kohler have better fuel efficiency.

Top Mowers Using Kohler Engines

When it comes to Kohler and Kawasaki engines, there are more lawnmowers available on the market using a Kohler engine.

There are a number of great lawnmowers on the market that have a Kohler motor in them. Brans like Husqvarna, Cub Cadet, and Craftsman all have popular models using Kohler motors.

You can find push mowers, riding mowers, and even zero-turn mowers with a Kohler mower engine.

The Husqvarna Z254F features a Kohler motor with 26 horsepower and is a fan favorite for larger residential properties.

Since it has a Kohler motor in it, you can pick up this zero-turn for a great price compared to other models.

Top Mowers Using Kawasaki Engines

Just like Kohler, there are several mowers using Kawasaki lawnmower engines.

The incredibly popular brand Gravely uses Kawasaki engines on many of their models, from zero-turn to walk-behind mowers.

The Gravely Pro-Turn 600 is a fantastic zero-turn that is used by homeowners and for commercial use.

Main Problems Reported With Each Engine


While most Kohler lawnmower engines are reliable, the new Courage model has several issues that customers have reported.

There have been reports of the engine case cracking, oil leaking, and more. Kohler has yet to address this issue fully, and while you’re not guaranteed a problem if you purchase a Courage Kohler lawn mower engine, you should reconsider if there are other options available.


Kawasaki gasoline engines aren’t exactly problem free, but the problems they do have are more in line with age and normal wear and tear.

Lawn mower engines will eventually need repair, it’s a fact of life. The idea behind whether or not an engine is reliable is how long it will take before it needs a major repair.

Luckily, a Kawasaki mower engine can last longer than most before it has a leaky gasket, fuel filter leak, and other problems.

Maintenance Considerations

There’s a checklist you should follow to perform less maintenance in the long run and keep your lawn mower engine running longer.

Like a car, you should regularly change the engine oil and oil filter if applicable. You should also use a fuel stabilizer and remove the fuel if you’re not going to be using the lawn mower for long periods of time.

Many owners overlook simple things like checking and replacing the spark plug or air filter. Most lawnmowers have air-cooled engines, and keeping the air filter clean will keep your engine from overheating.

Lastly, you should take care of the blades on the mower. Make sure they stay sharp and aren’t bent. Sharp, straight blades will give your lawn a better cut and keep your deck from getting clogged with clippings.

Other Things To Consider

If you’re looking at Kawasaki and Kohler’s gasoline engines, you should also consider the lawn mower they’re installed on.

While the engine itself is a great reason to buy a lawn mower, you should make sure that the lawn mower itself is a great fit for your needs.

Kohler and Kawasaki both make excellent engines, with some subtle differences between the two.


While we personally would prefer a Kawasaki engine, if we found a great zero-turn mower that checked all of our boxes, we wouldn’t pass on it just because it had a Kohler.

All-in-all, both brands have manufactured some great engines, and there’s a reason the top brands on the market use their engines in their products.

The Winner Between Kohler VS Kawasaki

It was hard to pick a clear winner, we do feel that Kawasaki is better all around when compared to Kohler.

While Kohler does have better customer service and is less expensive than Kawasaki mower engines, they simply don’t beat Kawasaki’s power and reliability.

Both brands are reliable, but Kawasaki definitely has a better track record – especially after Kohler’s Courage engine.

Kawasaki Critical Power Engines also meet that SAE J2723 standard showing that they stick by the horsepower ratings that they advertise. It’s important to know that when you purchase a 23-horsepower engine, that it will put out 23 horsepower.

While we wouldn’t pass up on a Kohler just because it’s a Kohler, if there were a lawnmower with a choice of a Kawasaki or Kohler motor, we would take the Kawasaki.

Brand Overview


Gravely mowers are designed to perform the American way. But do you know when its journey began?

Gravely was founded by Benjamin Franklin Gravely after he earned his first patent for his motor plow invention in 1916. Each Gravely machine is engineered with such powerful engines that make them tougher, faster, and super comfortable to deliver unstoppable precision in every session.


Originally, Shozo Kawasaki founded a shipyard to make an ocean-going steel ship in 1878, which has gone through numerous diversification phases and became today’s Kawasaki Heavy Industries Group.

Kawasaki engines are also a part of this Kawasaki Group. Check out this video to learn more about the roots of Kawasaki heavy industries.

Gravely Engine Vs Kawasaki: What Makes the Differences?

Let’s compare Gravely and Kawasaki engines based on their features and capabilities:

Kawasaki & Kohler Engine Failure | Why did they fail? | Engine Teardown @THEMOWERMEDIC1

Recoil Vs Electric Starter System:

Gravely engines feature an advanced recoil starter system. But Kawasaki features a typical electric starter system, whereas some models also feature an easy start feature.

all-in-one, guide, kohler, kawasaki, engine, which

Recoil Starter with IntelliStart technology:

Gravely engines use a recoil starter system, which uses a spring-loaded pulley to turn the engine over. They also use exclusively patented IntelliStart technology. This system allows the engine to start quickly and easily.

The only issue is recoil starter system often becomes difficult to pull if you have a cold engine or the grass in your yard is too tall.

Electric Starter with typical easy-start feature:

Kawasaki engines use an electric starter system, which uses a battery to turn the engine over. This starter system is more powerful than a recoil starter and easier to use in challenging cold weather.

Some of the Kawasaki engine models also have an easy start feature like the Gravely engines. But that does not match Gravely’s IntelliStart system. Also, this type of starter system is more expensive to maintain.

Gravely engine features a super easy and quick starter system. But if you need something more powerful for the extreme cold climate, choose the Kawasaki engine.

Gravely Two-cylinder Vs Kawasaki Three-cylinder Power System:

Gravely Engines have two cylinders. However, Kawasaki engines feature a three-cylinder design.

Things that state which power system is more powerful than another_

Pistons Piston rings:

Gravely engines feature lightweight pistons piston rings. Due to decreased inertia, it improves performance by reducing crankshaft bearing loading. Also, it reduces power-robbing friction and hydrocarbon emissions.

Kawasaki engine’s Forged pistons can endure higher temperatures and pressures than cast pistons. They can handle more power and last longer.

Improved Efficiency Performance:

Gravely designs the engines with an overhead valve and electronic fuel injection. Its new Air Inlet and Outlet Channel design improves the airflow and increases efficiency.

Kawasaki engines use high-performance camshafts that provide more lift and duration than competitors. It allows the engine to produce more power while still consuming less fuel.

Decreased Emissions:

Gravely engines feature catalytic converters. They reduce pressure loss at the intake and exhaust valves for lowered emissions.

However, Kawasaki engines feature an exhaust system for reduced emissions.

So, both ensure required reduced emissions.

Optimized Ignition System:

Gravely engine’s optimized ignition system boosts spark energy and lets the fuel/air mixture burn entirely. Also, it provides higher power output, shortens flame propagation, and improves combustion.

But Kawasaki engines use more advanced ignition that creates a hotter spark. It enhances combustion and ensures more power and fuel economy.

Run Time:

Gravely engines have a longer runtime since they have a durable built-in design.

On the other hand, Kawasaki engines are designed for speed and power. So, they have slightly less run time than the Gravely engines.

Both Gravely and Kawasaki engines are powerful. But the Kawasaki engine has more torque than the Gravely engine.

Gravely Vs Kawasaki Engine’s Fuel Efficiency:

Understanding the actual difference between these two engine types will help you pick the right one_

Gravely engines are designed with a higher optimized compression ratio.

They need less fuel than other branded engines to produce the same amount of power.

Their higher displacement also contributes to increased efficiency. This compression ratio decreases combustion temperature to provide more power.

However, Kawasaki engines have a lower displacement and compression ratio than Gravely engines.

That means Kawasaki engines consume more fuel to generate sufficient power.

Gravely engines have a 500cc displacement, while the Kawasaki engines feature only a 400cc displacement.

Similarly, Gravely has an 8.5:1 compression ratio, while Kawasaki has a 7.5:1 compression ratio.

The bottom line is that the Kawasaki engines consume more fuel than the Gravely engines.

Gravely Engine vs Kawasaki Engine Maintenance:

There are three key factors to consider when comparing the maintenance requirements of Gravely and Kawasaki engines:

Type of Engine:

Gravely engines are typically air-cooled, while Kawasaki engines are liquid-cooled.

Since air-cooled engines tend to run hotter and are more susceptible to overheating, they require more frequent maintenance than liquid-cooled engines.

Kawasaki Liquid-cooled engines need less frequent maintenance. But Kawasaki engines are more expensive to repair.

The Environment or Condition:

Generally, those engines used in industrial jobs typically require more frequent maintenance than residential or commercial used engines.

Gravely engines are designed for residential and commercial applications. But Kawasaki engines are designed for various industrial and off-road applications.

Since industrial environments tend to be more harsh, rough, and demanding on engines, Kawasaki engines will need more frequent check-ups maintenance.

If you need an engine for residential or typical commercial use, go for Gravely Engines. But for industrial use, you should select Kawasaki engines.

Gravely Engine Vs Kawasaki Lifespan, Warranty Service, Customer Support:

Gravely Kawasaki engines are built to last for longer than other competitors. They can easily last for hundreds of hours when properly maintained.

However, some Kawasaki engines have a life expectancy of 25 up to 40 years.

Service Warranty:

Kawasaki engines have a limited warranty of 2 to 3 years and cover service for the original purchasers.

Gravely offers a three-year limited warranty for most engines, which covers parts, labor, and certain other components.

Both brands offer extended warranties for some of their engine models.

Customer Support:

According to most consumer reports, Gravely has a more actively responsive and helpful customer support system. But Kawasaki often takes longer to get back to them.

If you want better customer support afterward, Gravely Engine will be a better choice than Kawasaki.

Which One to Choose Between Gravely Engine and Kawasaki Engine?

Gravely Engine and Kawasaki Engine both have their advantages and disadvantages.

Gravely engines are powerful, quicker to start, have better fuel economy, and are easier to maintain.

They are ideal for typical residential and commercial use.

But when you consider running your machine in harsh conditions where the machine will go through lots of abuse, the Kawasaki engines are more suitable.

However, Kawasaki engines are more fuel-consuming. Even their repair or maintenance is more expensive than Gravely engines.

So, you should choose and take the final decision based on your preferences and needs.

Maintaining a beautiful lawn can be a daunting task, especially if you lack the appropriate know-how and tools to handle the challenges that may crop up. Fortunately, LawnAsk is here to offer you an all-encompassing resource that covers everything you need to know about lawn care.
