How to Change a Self-Propelled Lawn Mower Wheel

In this article, we are going to instruct on how to change the self-propelled lawn mower wheel. Over time the wheel can become damaged or worn out, reducing traction and possibly the alignment of the mower. Depending on your mower model, the instructions for lawn mower wheel repair listed below may vary slightly. Always be sure to check your operator’s manual for detailed instructions.


Step 1 - Prepare the mower for maintenance.

Before you change a mower wheel, make sure the engine is cool. Then disconnect the spark plug ignition wire.

Place your self-propelled lawn mower on an even surface. Put the height adjuster at the highest level. Lift up the front side of the mower and place two pieces of wood under the mower deck frame between the two front wheels. Put down the mower so that the front of the deck rests on the wood.

 If your mower is front-drive, the motor is between the front wheels on the deck. If it’s a rear-drive, the motor is between the rear two wheels. Pop the casing off with a smooth screwdriver. Inside the casing, check carefully the gears for any clogs. If you notice any clogs, remove them with a screwdriver. If any of the gears needs replacing due to cracks, unscrew the gears with a screwdriver. Then replace the old gear with a new one, and tighten it into place with a screwdriver.

Step 2 - Remove the lawn mower wheel.

Adjust your mower height. If your lawnmower has a height adjuster, place it in a position that allows easy access to the wheel bolts. Using a socket wrench, unbolt the wheel and take off it from the unit.

Step 3 - Apply Lubrication.

To enhance the lifespan of your mower wheels, lubricate the wheels bushings with a dry lubricant such as graphite.

Step 4 - Replace the lawn mower wheel.

Secure the lawn mower wheel and adjust its height of the wheel to match the others. Spin each wheel. Check for any cracks. If a wheel seems arched, try tightening it by tightening the bolt in the middle of the wheel with a 3/8-inch wrench. If the wheel still looks arched after tightening the bolt, unscrew the bolt, and slide the wheel off. Replace the wheel with a new one, and simply tighten the bolt with the wrench.

Step 5 - Remove wood.

Remove the pieces of wood from under the mower deck frame between the two front wheels.

Step 6 - Ready the mower for operation.

After you replace the mower wheel, reconnect the spark plug ignition wire. While running your mower for the first time on the new wheel, keep an eye out for vibrations or shake, which could indicate the lawn mower wheel assembly was not properly replaced.
