You can get your lawn mower working back. Here all you need to do is inspect the cause and then solve it. Check the following instructions to solve it properly-

Cause 1: Lack of fuel

If your lawnmower has already run out of fuel then it won’t start! To check out the oil level, level your lawn mower on a ground surface. Then, put the dipstick tester into the gas tank for a few seconds. If the fuel mark shows a low-level mark then, of course, your lawn mower lacks fuel.

Solution:

Start filling the gas tank until the fuel mark of dipsticks touches the top hole. Then, start the lawnmower and see if it starts or not.

Tips: Don’t overfill it. Otherwise, it will be pretty hard on the small engine and can cause a lawn mower to smoke

Cause 2: Defective Spark Plug

A dirty spark plug, loose connection or disconnection of the spark plug can create the problem of starting a lawn mower.

First, remove the spark plug wire. Then, use a spark plug wrench to loosen it. After removing the spark plug, check its condition.

Solution:

If the spark plug is dirty or covered with carbon then you need to clean it with a soft wire brush. Or you can also spray-on spark plug cleaner. Check the gap of the spark with the spark plug gapping tool. After cleaning it, you have to reinstall the spark plug. Start the lawnmower to know it works. If it won’t start then replace a spark plug with a new one.

Cause 3: Old or Bad fuel

As many of us have the issue of the yard machine, the lawn mower won’t start after winter. This is because of the remaining fuel in the lawn mower from last year. The old or bad fuel in the carburetor float bowl can clog up the carburetor. It can also clog fuel filters and fuel lines.

Solution

Draining out the old or bad fuel. Then, fill the carburetor bowl with new and fresh fuel. Add a fuel stabilizer to get rid of any dirt, dust or debris inside the fuel system. Now start the lawn mower and see the result.

Cause 4. Dirty carburetor

A carburetor’s main function is to regulate the right amount of gas with the air for combustion in the engine. Hence, the engine can regulate or start. But, when the carburetor gets dirty or clogged, the engine can’t start. Using old fuel that contains ethanol can clog the carburetor.

Solution

Yard machine lawn mower carburetor cleaning is easy by following the given instructions-

  • Remove the air filter and spray carb cleaner in the air intake
  • Remove both throttle cable and choke cable
  • Next, remove the nuts, and screws attaching the carburetor.
  • Twist a carb to remove the spring
  • Unscrew the bowl.
  • Check the stem for clogged holes with a thick wire. Clean the clogged hole with this wire and a carb cleaner.
  • Try to check the gasoline inside the carburetor. If it’s fresh and good, then it’s fine.
  • After cleaning the parts, re-install the carburetor.

Cause 5. Bad battery or loose connection among terminals

Due to the insufficient charge in the battery, your lawn mower’s engine can’t start. Loose connections or corroded cables can also be the reason. That’s why, before starting the lawn mower charge the battery and inspect the connection carefully

Solution

Take a multimeter to check your battery. The reading of the battery should be between 12.4 to 12.8. If the reading is less than 12.8 then your battery needs to charge. After charging the battery, start the lawn mower. If it does not work then replacing the battery is the better option.

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.

Zero-turn mowers and lawn tractors provide the wide decks and speed needed to maintain large yards. However, they have their pros and cons, which could make one a better choice for your yard.

Lawns over half an acre give you plenty of space to play and lounge in the great outdoors. However, when it’s time to mow, you’re looking at a major commitment. Factor in landscaping like flower beds and trees, and you’ll likely add some trimming and spot mowing to your to-do list. The power machines of the landscaping world—zero turn vs. lawn tractor—can keep you from spending the better part of every Saturday behind a lawn mower.

A lot of factors go into determining which type of mower would be best suited for your lawn. Your yard’s size, incline, and landscaping all come into play. Before choosing between the two most common lawn mower types for large yards, get to know the biggest differences between zero-turn mowers and lawn tractors. This guide lays out the pros and cons of each to help you avoid making a mowing mistake with the wrong mower.

Zero-turn mowers are better for lawns with curves.

If your yard spans ½ an acre or more and is dotted with trees, bushes, and flower beds, a zero-turn mower will save you time when it comes to your lawn care routine. Zero-turn mowers have dual-hydrostatic transmissions controlled by two levers, which are key factors in their responsiveness and tight turning radius.

To move forward in a straight line, you press both levers forward, making sure to keep them even. To turn the mower, you either slow or stop power to one side by pulling the lever back, while the other side continues to move forward, giving the mower the ability to do a zero (or near zero) radius turn. This gives zero-turn mowers a mowing pattern that leaves far fewer missed patches of grass at the end of the swath or around curves and corners.

In comparison, lawn tractors have a wide turn radius, which leaves a patch of grass at the end of every swath. You can either come back around on a second pass to get those missed patches or stop and reverse to cut every blade of grass.

Lawn tractors power over slopes and hills.

Lawn tractors have a front-wheel drive that allows them to inch up slopes and hills with relative ease. In contrast, a zero-turn mower’s rear-wheel drive may be difficult to control or lose traction on uneven ground.

However, a word of caution: Both types of mowers can tip over on extreme slopes, which is anything over 15 degrees. Some lawn tractors and zero-turn mowers have roll bars and seat belts, but you’re better off using a push mower or a trimmer on extreme slopes.

A lawn tractor’s steering wheel provides intuitive control.

For those who want to jump on the lawn mower and go, a lawn tractor’s familiar steering wheel and gas pedal will take little if any time to get used to. Basically, you push the gas pedal and go, just like you would in a car. When you want to slow down, you release the gas and press the brake.

The differential speed control offered by a zero-turn machine’s dual-hydrostatic transmission, on the other hand, can take some practice. On these models, you control the speed by pressing the control levers forward rather than using a foot pedal. Hydrostatic transmissions can be touchy, so there may be some lurching and sudden stops until you get a feel for the speed control.

You also have to learn how to time the manipulation of the levers (one pressing forward, the other pulling back) when making turns. Considering that zero-turn mowers can go faster than lawn tractors as well means you’ll be trying to learn how to control the machine at higher speeds.

If you’re nervous about controlling a zero-turn model, a few newer machines have joystick control, which is much easier to use but still requires practice to master.

Deck size makes a difference, but the winner will depend on your yard.

The wider the deck, the fewer swaths it will take to cover the lawn, and the faster you can mow your full property. Lawn tractors have decks that range from 42 to 54 inches, while zero-turn mowers have decks from 42 to over 60 inches.

Choosing the appropriate deck size (and the mower or tractor that provides it) not only involves considering the size of your yard but also the width of the narrowest spaces you’ll need to mow in between or around. To maintain tight spaces between trees or flower beds, you’ll need a narrower deck. However, if you have a flat yard that’s 2 or 3 acres without obstacles, choose the machine with the widest deck you can afford.

Zero-turn mowers go faster, but slower speeds leave a cleaner cut.

Zero-turn mowers offer clean cuts at 5 miles per hour (mph) and can reach speeds of more than 10 mph. In comparison, lawn tractors mow at about 4 mph with a top speed of around 7 mph. However, in some circumstances, such as on sloped or hilly terrain, lawn tractors may be able to maintain their traction and speed better and, therefore, may occasionally mow faster under certain circumstances.

Know that cut quality goes down the faster you mow, whether you’re on a zero-turn or lawn tractor. Even if you have a zero-turn mower, the top speeds are generally used for traveling to another part of the yard rather than actually mow the lawn.

Both types of mowers are pricey, but zero-turn models rise to the top.

When it comes to price—zero turn vs. lawn tractors—both top the price charts. However, lawn tractors are the more affordable of the two, and they’ll earn their keep. They may also be used to pull carts, sprayers, spreaders, and other yard equipment. For the right buyer, a lawn tractor may be a Smart investment. A base model starts around 1,200, but any extra accessories like a bagging kit, trailer, or sprayers must be purchased separately.

Zero-turn mowers start around 2,500 and go well above 5,000, and you may have to buy a bagging kit separately. If your yard spans several acres and/or has a wide range of trees and flowers you need to mow around, a zero-turn model may be well worth it for the time it saves.

Had my 148z since 2006. Been waiting on it to tear up so I can trade up. No such luck. 3rd Gravely in my family. Dad bought his last in 1965. Cut grass into the 90’s. Just a review for the lasting.

Lots of power, heavy duty construction, and great service from the folks at Triple C here in conway Ar. Twenty hours on it so far, and love it.

This mower makes a clean cut, is very easy to drive and is sturdy. The transaxles are heavy duty which is important when pulling a large leaf vacuum machine. The owner’s manual is not complete in that.
