Husqvarna mower deck leveling. 12 Reasons a Husqvarna Mower Has a Bad or Uneven Cut

Reasons a Husqvarna Mower Has a Bad or Uneven Cut

You noticed your Husqvarna mower is giving you a poor cut lately. Your mower might be scalping your yard, leaving uncut strips of grass, cutting uneven, or leaving your grass with brown tips.

Any of these problems can be frustrating to see after you’ve invested a significant amount of money into your lawn mower, but there is a fix to your problem.

A Husqvarna lawn mower may give a bad or uneven cut when the mower blades are worn, damaged, or installed incorrectly; the tire pressures are uneven; the deck is not level or clogged; the deck components are damaged; the engine speed is too low, or the ground speed is too fast.

I’ll share will you what to look for when identifying the cause of your uneven cut so you can get back to having a nice-looking lawn.

Reasons Your Husqvarna Lawn Mower Has a Bad or Uneven Cut

Husqvarna Mower Blade is Worn or Dull

Worn mower blades can cause your mower to leave strips of uncut grass. Extremely worn blades become thin on the sails of the blade and need to be replaced with new Husqvarna blades once they reach this point. Honestly, they actually should have been replaced well before reaching this point.

Unless you are checking your mower blades’ condition frequently, you may not have seen your blades getting pretty worn down. A good indication of dull mower blades is the cut you get.

Your grass may turn brown a day or two after you mow the lawn and look pretty unhealthy. This could be a sign your mower blades are bad.

Take a look at the tips of your grass blades. If they turned brown because your dull mower blades beat them up, you will see brown tips with little cuts or tears in them. This is what happens when your grass blades don’t receive a precise cut with a sharp blade.

Remove and replace your Husqvarna blades. If your blades are still in good condition, you can just save a little money and sharpen your mower blades. I write about different methods to sharpen your mower blades yourself in “Inspect, Sharpen, and Change Your Mower Blades”.

I also recommend having your blade professionally sharpened if you don’t want to attempt it yourself. That’s what I do because I receive a much better edge from the professional than I am able to achieve.

Low Pressure in Your Husqvarna Tire

The cause for your mower deck not sitting level is not always a problem found in your mower deck. When one of your tire pressures is lower than the other, the deck sits unevenly. Check your tire pressures and make sure they are set to the manufacturer’s specifications.

The left and right-hand tires on your Husqvarna mower must have the same tire pressures. Check the tire pressures before assessing whether your blades are bent or your deck is not sitting level.

If you don’t check your tires first, you could end up replacing blades or making adjustments to your deck that you didn’t need.

Husqvarna Mower Blade is Bent

A mower blade that has impacted a hard object can become bent causing an uneven cut. Sometimes it’s pretty noticeable you have a bent blade. I’ve seen them bent at a 90-degree angle before.

Other times your mower blade may be so slightly bent it can be hard to visibly notice the bend. Even the slightest bends in your mower blades can cause a bad cut and send a vibration through your lawn mower.

You can check for a bend in your mower blade using one of the following methods:

Method 1: Remove each mower blade and lay it on top of a new mower blade to check for a bend. This will require you to have a new mower blade on hand which you may not have.

If you don’t have a blade to match your mower blades to or you simply don’t want to take the time to remove your mower blades at this time, use the next method.

Method 2: Find a flat-level spot to park your Husqvarna mower. Again, make sure your spark plug boots are unplugged before you work on your mower deck.

Once you are sure there is no chance your mower can start, grab a blade end and measure from the ground to the end of the blade. Record the measurement.

Next, spin the blade 180 degrees and measure the opposite side of the blade from the ground to the end of the blade. Compare the two measurements. If you find the measurements are greater than a 1/8” difference, you must replace the mower blade.

Continue using the same method to measure any additional blades your Husqvarna may have on the mower deck.

Do not attempt to straighten a bent blade. Straightening the blade will compromise the integrity of the metal making it weak.

Using a compromised mower blade on your Husqvarna while it is rotating at very high speeds can put other people or items at risk of being hit by a flying piece of metal if it breaks off.

Husqvarna Mower Blades are Installed Incorrectly

The sail of the mower must be pointed upward toward the deck when installed correctly. Check your mower blade as many of them are stamped to indicate which side of the mower blade faces up and which side faces down.

If you can’t find anything stamped on your blade, just remember, “Sail Up”. Making the mistake and placing your mower blades upside down will not only damage your yard, but it can cause damage to your spindles and spindle housings.

When the blades are attached with the sails facing toward the ground, the sails can hit the ground and beat up the grass. The impact of the sails hitting the ground is what can cause damage to your spindle housings.

Easily Fix Your Bent Mower Deck (Cutting Uneven)

Balance Your Husqvarna Blades

Husqvarna mower blades must be balanced so you receive a level cut, reduce vibration in your mower, and prevent spindle housing damage.

Your blades are balanced when they have equal weight on each side of your mower blade. When the blade is heavier on one side, you must shave some metal off of the blade until each side is of equal weight.

The best way to check for equal weight is by using a blade balancer.

Some people choose to use a method where you place a nail on the wall and hang the blade from it. While this method can work, it is not always the most accurate.

Husqvarna Mower Deck is Plugged with Grass

It’s hard to avoid grass and debris collecting under your mower deck. There are a couple of things you can do to minimize the buildup. Don’t cut your lawn in wet conditions as wet grass sticks to the deck and leaves clumping of grass in the yard.

Some Husqvarna owners choose to use a deck spray designed for mower decks to keep grass from sticking. Although this product does help, it doesn’t keep everything from sticking so you’ll still have to scrape your deck periodically.

Grass that plugs up under your deck doesn’t allow air movement and a good suction to form under the deck. The blades can also be hitting debris in the deck which each passing.

Your Husqvarna’s good cut relies on the speed of your blades creating air movement. This air movement in the deck creates a suction that pulls your grass tall so the blades can pass by and create a nice-looking cut.

Keep your mower deck clean by performing regular cleanings. Scrape the deck using a deck scraper or wire brush to remove all grass and dirt stuck to the bottom of the deck.

Husqvarna Mower Deck is Not Level

When your mower deck doesn’t sit level, you will definitely have an uneven cut. Now, you should have already checked your tire pressures to make sure you don’t have a low tire that is throwing off your deck level.

If you didn’t, check your tire pressure before checking the deck level.

To check the level of your deck, you will need to park your Husqvarna on a flat-level surface. Measure from the ground to the deck on each corner of the mower deck. Record the measurements. Compare measurements from side-to-side and front-to-back.

You will want to make sure the deck has the correct pitch where the front of the deck sits slightly lower than the back of the deck.

Because mower deck level specifications and adjustment procedures can vary by deck type, refer to your owner’s manual for further instructions.

Husqvarna Blade Spindle is Bent

A bad spindle or bearing in the spindle housing can be the cause of your bad mower cut. In order to check for problems in your spindle housing, you’ll need to put on a good pair of work gloves and grab a hold of each side of the mower blade.

Firmly gripping each side, rock the blade up and down. What you’re looking for is any movement or a knocking sound. If you find either of these conditions present, you will need to take apart your spindle housing as it is most likely an indication of a bearing failure.

Bad Mower Deck Belt or Pulleys on Your Husqvarna

The next items to check on your mower deck are the pulleys and belt. Turn each pulley on the deck to make sure it moves smoothly and you don’t encounter any resistance.

Also, listen to the bearing noise when you are turning the pulleys. If you hear noise or encounter resistance, you need to replace the pulleys because the bearings are failing.

You will need to check the deck belt for signs of wearing including a glazed appearance, cracking or fraying. A belt that shows signs of wearing can fail to turn your mower blades at their top speeds. Replace your worn belt.

Your Husqvarna Engine Speed is Too Low or Ground Speed is Too Fast

Your mower deck needs engine speed in order to cut at its best. Run your mower at full throttle to keep your blades spinning fast. In addition to running your mower at full throttle, you must also gauge your mower’s ground speed.

Adjust your ground speed to your conditions. For example, if you are mowing thick, tall, or wet grass, you will need to slow down your ground speed so you don’t put too much of a load on your engine.

Moving too fast across your lawn can also cause you not to get a good cut as your mower may be pushing over some of the grass instead of standing it tall.

Incorrect Overlapping Path with Your Husqvarna

You may be the type of person that tries to get their mowing done in less time by making your mowing paths the widest you can. Not everyone enjoys spending as much time with their mower as they can.

If you are noticing small strips of grass once you get done mowing, make sure you are properly overlapping your cuts so you don’t miss cutting any parts of your lawn.

Husqvarna Mower Deck Shell is Damaged

A deck shell can get tweaked by running your mower into objects like trees, rocks, and other hard surfaces. The deck shell is formed to create a suction to give you a good cut. If the deck has been damaged, your cut could also be compromised.

You’ll need to try to repair your Husqvarna deck or you may need to replace it altogether. If you do replace the shell, you will have to move the components from your old deck onto the new deck shell.

Your Lawn is Uneven

When your lawn is uneven and bumpy, your mower deck can scalp your lawn leaving you an uneven cut. You will either have to deal with this or you can get a lawn roller and try to even it out.

Mowing ditches with a wide format mowing deck can also provide a bad cut or a stair step type cut because it isn’t able to follow uneven curves. It’s best to use a push mower with a smaller format deck in these areas.

Still Having Problems with Your Husqvarna Lawn Mower?

If you are still having problems with your mower, check out my guide on common problems owners encounter with their lawn mowers.

I put together a chart to identify causes and solutions to problems including starting, smoking, cutting, vibrating, dying, and more.

If you don’t feel comfortable troubleshooting and performing repairs on your lawn mower, it’s best to contact your local Husqvarna dealership or lawn mower repair shop for assistance.

You must remain safe and only perform repairs you are mechanically able to perform to avoid injury or further damage to the mower.

Follow these Steps to Adjust Mower Deck on Husqvarna Zero Turn Mower

So, it is finally the time to say goodbye to old hard days where you could not cut the grass evenly. It is time that you make some small adjustments responsibly and get your mower back to effective cutting.

Below given are the steps involved in Adjusting the Mower Deck on Husqvarna Zero Turn Mower: –

  • The first and the most basic step of adjusting a mower deck is to park it to a flat surface.
  • Once you get it parked using the foot brake lever, then turn the clutch switch towards the left-hand side of the dash upwards to loosen the cutting blade.
  • Now push the attachment lift lever to the maximum height that it can reach and turn off the ignition and remove its key.
  • Once you remove the key, open the hood where the engine is placed and unplug the black-colored rubber spark plug.
  • Now, before moving further, allow the engine to cool completely.
  • Now that your engines are cool, take out the valves from each tire and measure its pressure using any pressure measuring device.
  • If the result of the pressure comes to be less than 15 PSI, then it means that the tires are not inflated properly. The required pressure for a Husqvarna mower is at least 15 PSI. So, try to inflate the tires at least till they reach the alignment stage.
  • The tires are pretty much sorted. So now we need to work on the blade section of the mower. Before beginning your practice, ensure to have worn your gloves to avoid unnecessary actions.
  • Now, make a note of the distance between the left side of the blade to the ground and the right side of the blade to the ground.
  • The next step involves finding the lift adjustment nuts usually placed, one on the left side while the other on the right side.
  • Now turn the lift link adjustment nuts clockwise and anticlockwise as per your need to bring your deck in alignment.
  • Using these lift link adjustment nuts and an adjusting wrench, try to level or position the right and the left side of the deck at an equal distance from the ground/bottom.
  • Once you are done with the adjustments. Now you must rotate the blade in a 90° direction to make the tips pointed towards the front back of the deck.
  • After positioning them correctly, you need to record the distance of both the front the back tips of the blade to the ground.
  • Now compare your measurement. It should be ⅛” to ½” lower than the back measurement. If you do not find the same, then adjust again to a proper height.
  • There is a jam nut placed on the front of the mower that is entirely responsible for the positioning of the blades correctly. Loosen the jam nut and reach the Adjusting nut by moving it anticlockwise.
  • Now that you have reached the adjustment nut, rotate it clockwise if you wish to raise the height of the blade or rotate it anticlockwise if you need to lower the blade.
  • Keep doing till you acquire the desired ratio.
  • Once you acquire the desired ratio, adjust everything back to normal.
  • Lastly, replug the black color rubber plug that we removed in the beginning.

And thus, you successfully finished adjusting your Lawn Mower.

It would also be great if you could have some other person around while practicing your adjustment.


If your mower is not giving you the expected cut of grasses, then it means that it somewhere needs fixing. And as an owner, you need to analyze and understand it responsibly. Uneven cutting of grasses is a common problem but needs your attention to avoid any further major damage.

Henceforth, adjusting your mower is significant. The above-discussed steps can efficiently help you do that. All you need to do is follow it religiously responsibly.

How to Level a Mower Deck (4 Easy Steps)

Leveling your lawn mower deck is a crucial part of lawn mower servicing. An out-of-level deck will result in an uneven cut with what look like “steps” in your lawn. Modern lawn tractors and zero-turn mowers allow you to adjust the deck relatively easily so that you can achieve a perfectly even cut lawn. Follow my step-by-step guide below to level your riding mower deck.

Signs that You Need to Level Your Mower Deck

Here are common signs you can look out for to identify if your lawn mower deck is not level. You’ll be able to notice potential issues with the deck by simply inspecting the cut your lawn mower is making.

  • One side of the lawn mower is cutting lower than the other
  • Steps in the lawn between cutting strips
  • The grass isn’t being cut well, even with sharp blades

The Equipment You’ll Need On Hand to Level Your Riding Mower Deck

You’ll need a level surface to work on to level your mower deck accurately. The adjustments are fractions of an inch, so use the most level work area you can find. Then you’ll want to collect the following tools:

How to Level a Mower Deck (Step by Step)

The principles and preparations are the same when leveling zero-turn decks or lawn tractor decks. To achieve accurate leveling, you’ll need to follow these steps.

Preparing the Lawn Mower

To start leveling, you’ll need to have a safe and level lawn mower. Begin by positioning your lawn mower on your level surface. Next, apply the brake and raise the cutting deck to full height. Next, remove the spark plug, so the lawn mower cannot start.

With the lawn mower on level ground, you’ll next want to equal the tire pressure. Take your pressure gauge and measure the front tires. Inflate the front tires so they are of equal pressure, matching the tire inflation recommendations stated on the tire. Once done, you can repeat this for the rear tires. Additionally, your tire sizes must match. If you have odd tires, you’ll never be able to level your mower deck.

Inspecting the Blades

The next step in the leveling process is checking that the blades are straight. First, position the blade so that the tips point toward the sides of the mower instead of toward the front and back.

Then measure the outer tip from the ground up to the blade. Next, rotate the blade 180 degrees and measure the opposite blade tip. Both measurement results should match. If they don’t match, your blade is bent and needs replacement. Repeat this process for each blade on your deck.

Adjusting the Lawn Mower Deck Side-to-Side

We will adjust the deck in two stages. The first step is the side-to-side adjustment. Position the blades so the tips point towards the sides of the mower. Next, measure the outer tips from the ground up to the blade for both the left and right blades using your measuring device and write down the results.

Your end goal is to have both sides of the deck measuring within ⅛ inch of each other. You’ll only need to adjust one side of the deck to achieve this. Using your wrench, adjust the lift link adjustment nut on one side of the lawn mower. Usually, clockwise is up, and anti-clockwise is down. You’ll raise or lower the deck by making minor adjustments to the adjustment nut.

Alternate between adjustments and measuring the blade tip height. Once you have achieved the desired height, confirm by remeasuring both sides of the deck.

Adjusting the Lawn Mower Deck Front-to-Back

The second step is leveling the mower deck front-to-back. The front of the deck should be ⅛ – ½ inch lower than the back.

Start by positioning one of the blades, so the tips point towards the front and back of the mower. Then measure the height from the ground up to the blade of the tip facing towards the front. Next, measure the height from the ground up to the blade of the tip facing towards the back. Note the results of both measurements.

Grab your wrench and locate the front lift link adjustment nut. Your adjustment will alter the height of the front of the deck. Your goal is to get the front to be ⅛ – ½ inch lower than the back.

Adjust the nut clockwise if you need to raise the front of the deck. If you need to lower it, make anti-clockwise adjustments. Once done, remeasure the blade tips pointing front-to-back and confirm the mower deck is level within the desired range.

What if You Don’t Need to Make an Adjustment?

When you measure the blade tips, you may find that you don’t need to make any adjustments. You probably fixed the leveling problem by simply inflating the tires to equal pressure and ensuring the blade is straight. This shows you that proper tire pressure and good-quality blades are essential to achieving a perfectly cut lawn.

Lawn Mower Height Settings (adjusting your mower deck)

Understanding your lawn mower height settings and how to adjust your mower deck properly will help you get the most from your lawn. Mowing your lawn at the correct height improves your lawn’s health and appearance. Proper mowing can also helps prevent weeds from germinating.

In this article, I’ll explore how you can find the right mower height for your mower (and grass type), and provide some basic instructions on how to change your mower deck height for different kinds of mowers. I’ll also explain why different height settings exist on mowers (and when you might need them). Finally, I’ll tell you exactly how to use your mower deck settings effectively to get the best results when using your lawn mower.

Let’s start with the absolute basics.

Inches or Taller is (Usually) the Best Setting

When choosing the right height for your mower, the time of year is one of the biggest factors that will determine the mower height setting you should use.

I recommend that most people increase the mower height to a minimum of 3-inches from the middle of April through September. Depending on your mower, this might be its highest setting.

Why would you keep your mower setting at 3-inches, which is often the tallest setting?

Keeping your mower set this high will:

  • Help the lawn conserve water
  • Promote the development of deep digging roots
  • Boost turf density
  • Improve turf color

The only times when you shouldn’t use this high setting is when you are doing the first and the final mow of the season. At these times, a 2.5-inch mowing height is best for most cool-season lawns (though at the end of the year I’ll sometimes go lower because of how I clean up my leaves).

Many homeowners imagine that the middle setting is best for their lawn, but this isn’t the case. In most cases, it’s too short. You should almost always go with the highest setting.

Some exceptions exist, however, based on your grass type. Some types of turfgrass look and grow best when mowed shorter than the recommendations I’ve detailed above. Bermuda is just one example. Often used for golf courses, Bermudagrass can thrive when mowed frequently at a low height.

There are several other warm season grass types grown in the southern US which will perform well when mowed at a shorter height. For many cool season lawns, mowing high will benefit the health and appearance of your lawn.

You can learn more about the different turfgrass growth habits and conditions unique to the three primary grass growing zones in the US right here.

Tall Grass Promotes Deep Roots

When your grass is allowed to grow taller, the plant will develop deeper roots. The roots of your grass will usually grow approximately three times as deep as how tall it is.

When grass is mown to one inch high, the roots will usually only extend to about 3-inches deep. At two inches high, the roots dig to about 6-inches deep. At three inches high, the grass roots can dig as deep as 9-inches.

Deep roots are the key to a dense and healthy lawn. Your grass will be able to access water deep in the soil between rainstorms, will retain its green color longer during the dog days of summer, and generally be more healthy and resilient.

Mowing Schedule for a Lawn Kept Tall

It’s best to mow your lawn once weekly and never take off more than 33% (or one-third) the height of the grass blade.

husqvarna, mower, deck, leveling, reasons, uneven

If you mow less frequently, you might find yourself taking off more and this, which is bad for the lawn.

Also, taking off only a little a time is good if you want to leave the clippings on your lawn for extra nutrition. If you leave too thick a layer of clippings on your lawn you can end up with thatch buildup, or even smother and suffocate your lawn.

Why Have You Seen So Many Short Lawns?

Given how important it is to keep your lawn relatively long, you may wonder why so many people go the opposite route and cut their lawns short. There are a few different reasons:


Some people think a lawn that is cut on a short setting has better aesthetics than a taller lawn. Of course that’s subjective, and what’s attractive to one homeowner isn’t to the next.

But what’s universally true is that the preference for a short lawn will often negatively affect the health of that lawn.

When a lawn is cut short, it is thinner, needs more water, is more prone to weeds, and will have shorter roots. It will also probably not have that ideal green color we all want.

Confusion Over Lawn Mower Height Settings

As mentioned earlier, many homeowners assume that the middle height setting on their lawn mower must be best. If you don’t know the proper height setting, go with something average, right?

Wrong. The highest setting is often the best one for your grass. And remember that the numbers you see on the settings (if your mower has numbers) don’t link with the lawn cutting height.

Always remember to put your mower on the highest setting or to cut your grass at a minimum of 3″ to ensure your lawn stays healthy.

Golf Courses

Many people admire the look of green golf course grass and assume that if they cut their lawns the same way, they will have the same wonderful green color.

This is a mistake, as golf courses actually use special kinds of grass that allow them to keep their courses cut so short.

Most homes have lawns with grass that cannot thrive when mowed so close to the ground.

How to Change the Height Settings on Your Mower

The first step when you want to change your mower’s height settings is to consult with the manual.

The manufacturer’s manual will have information on how to increase and lower the setting of your mower. The way to adjust the mower and what the different adjustments mean vary from brand to brand of lawn mower.

A common mistake is to just assume that you understand all the ins and outs of your mower. You’d be surprised at the features and nuances you can learn when you take a few minutes to read the manual.

Once you understand the instructions in the manual about how to change the settings, do the adjustments on a flat surface. You will need to put the mower on a flat surface to see how low or high the mower is. A flat pavement surface (driveway) or a garage is a great place to do this.

And don’t make the mistake of thinking that the bottom of your mowing deck is the height at which your grass will be cut … your mower’s blade is usually higher.

Pick Settings Based On Your Grass

As we’ve already mentioned, most types of grass grow best with the highest setting on most mowers.

If you aren’t sure, or are unhappy with the results at this setting, I recommend starting high and then adjusting the deck lower one setting at a time until you get to a mowing deck height you’re happy with.

Before you start making your adjustments, ensure the mower is completely turned off and will not turn back on. That is an essential safety precaution and crucial for preventing injury.

If you have a gas mower, you will find a safety catch to hold down for the mower to run. Ensure that this is not being pressed by any kind of object. It’s best to remove the spark plug from the mower so that there’s absolutely no possibility it can start.

Many modern push mowers (and even some reel mowers) can make height adjustments just by moving a lever. Some types of mower may require adjustment of each wheel one at a time. If you have this kind of mower, ensure that you don’t inadvertently adjust each to a different height. If you do you’ll get an uneven mow job (or just go in circles).

You may need a wrench, screwdriver, and perhaps other tools to adjust wheel height.

Adjusting Height Settings on a Rotary Mower

As we mentioned earlier, the exact procedure for changing the setting on your mower will vary from manufacturer to manufacturer and model to model.

However, there are certain things you can keep in mind if you have a rotary mower, be it a push mower or self propelled.

If you have a very inexpensive or entry-level mower, it will probably have a very basic procedure for height adjustment. If you have an expensive model, it will be easier and faster to adjust.

Axel Adjustment

One of the most basic kinds of height adjustment is axle adjustment. Using this method, you will physically take off the wheels and put them at a higher setting. This will usually involve a snap-in system. If you have a very inexpensive or entry-level mower, this is probably the system you will use for adjusting height.

Individual Wheel Levers

Another type of method some rotary mowers use involves individual levers.

Using this method, each of the mower’s wheels has an individual lever. You’ll use these to raise or lower the height. In order to level the mower, you will have to adjust each individual wheel to a uniform setting.

This is the type of mower deck adjustment my Honda self propelled mower has, and I find it very easy to use.

Single Lever System

If you have a high-end model or a riding mower, you might find it uses a single lever system.

This is easy to use and involves using one lever to raise the deck. You’ll find the lever to one side of the machine, frequently close to the axle.

The name of this system is often the “central single lever height adjustment system.”

Riding Mowers are Usually Complicated

Adjusting the height settings on a riding lawn mower is usually more complex and can vary considerably from model to model. My best advice is to thoroughly read the owner’s manual that came with the riding mower to make sure you know what you are doing.

If you can’t find your manual but have the manufacturer and model number of your mower you can find and download the manual with a quick Google search.

When in Doubt, Set Your Blade High for a Healthy Lawn

Many experts explain that keeping your lawn taller (three inches or higher) is best for grass health, and I agree with them.

Mowing high will put your grass in a better position for dealing with conditions such as drought or hot weather. It is also helpful if your lawn has to deal with shady conditions.

When the weather gets a little cooler, you can usually cut the grass a little bit shorter if you want to. If you don’t know what kind of grass you have, a good rule of thumb is to cut it at three inches or down to a minimum of 2 ½”, never removing more than one third of the grass blade at a time.

Understanding your model of lawn mower and how your lawn mower height settings work is important if you want to use it properly. Read the manual that came with your mower to understand how its height settings work and how to adjust them.

Once you understand what to do and how to do it, you will know how to customize your mower for the healthiest lawn.

Should a Mower Deck Be Level Front to Back?

It is critical to have a properly leveled mower deck when it comes to maintaining a healthy lawn.

A level mower deck from front to back helps to ensure an even cut. It prevents scalping or uneven patches of grass. It also aids in the prevention of excessive wear on the mower’s blades and other components.

In this article, we’ll look at should a mower deck be level front to back, as well as some tips for keeping your mower deck level.

What Are the Effects of an Unlevel Mower Deck?

An unlevel mower deck can result in uneven cuts on your lawn. Because the blades may scalp the high spots while leaving the low spots uncut. your lawn will look uneven and unsightly.

It may reduce mower efficiency as it will take multiple passes to get a consistent cut. This lengthens the mowing process and increases fuel consumption.

Uneven wear and tear on the blades, bearings, and other components can result from an uneven mower deck. This brings you to costly repairs and a shorter mower lifespan.
