Leveling a riding mower deck may be what you need to do if you find that your riding mower is not cutting your grass in an even manner. If you find that the mower may be scalping the yard and creating ruts, the best thing to do is get out your tools. Fixing this problem is a very easy task to complete and will not take up much of your time. There are a few tools that you will need, but you should have those around the house.

Using these simple steps will have your yard looking great the next time that you mow.

Step 1: Set the Brake

The first thing that you should do when you get ready to level your deck is to place your riding mower on level ground. This is important because you will be using the ground for your measuring foundation. Once you have the mower on level ground, you should then place the parking brake on. Always make sure that you have the parking brake on before you make any repairs. If you do not have the parking brake on, the mower can roll back and possibly injure those working beneath. After the hand break is set, raise the deck to the highest position possible.

Step 2: Measuring

Once you have the parking brake on and the deck is raised, you will then measure the bottom of the deck to the level ground. Use your tape measure for making this measurement. Make sure that you take the measurement on both sides of the deck, because this will let you know how out-of-level one side may be. The deck sides do not have to be completely level but a good rule of thumb is to make sure they are at least within a quarter of an inch with each other. If you need to adjust, only adjust one side.

Step 3: Adjustments

If you find that your mower is in need of adjustment, you will locate the link adjustment nut. The nut is on the lower part of the deck suspension arm. There are sometimes two nuts. By adjusting one of the two nuts, you will adjust the sides of the mower deck. After you have adjusted the nuts, you are ready to measure once more.

Step 4: Measuring

After you have made your adjustments, you must take another measurement of your mower deck. By this time, the adjustments that you have made should have leveled the deck up. If you are off, you should remember that approximately one full turn will lower or raise the deck an eighth of an inch. By keeping this adjustment in mind, you will be able to only adjust the deck once when the time comes that you need to adjust again. By avoiding bumps and debris that can cause damage to your deck, you will find that you will have to adjust fewer times in the future.
