How to replace a lawn mower wheel

This lawn mower repair guide gives step-by-step instructions for how to replace a lawn mower wheel. Lawn mower wheels can wear out with normal use. Fortunately, replacing a wheel is an easy repair. Before ordering the replacement lawn mower wheel, also check the axle shafts for wear and damage. Replace worn axle shafts at the same time to prevent the new wheels from wearing prematurely. Replace the wheels and axle shaft using the manufacturer-approved replacement parts.

These steps show how to replace the wheel on common Craftsman, MTD, Cub Cadet, Husqvarna, Yard-Man, Troybilt, Toro and Murray walk-behind lawn mowers.

Instructions

1. Elevate the mower

Wear work gloves to protect your hands.

Lift the mower and slide a block of wood under the housing to support the mower with the wheels off the ground.

If the mower is heavy, have a helper lift the mower while you position the block of wood. 

2. Remove the wheel

Use a slot screwdriver to pry off the hub cap.

Remove the nut that secures the wheel to the axle shaft and slide the wheel off the shaft. If the nut has a washer, remember its location.

Tip: If your mower has a cotter pin instead of a nut, use pliers to remove the cotter pin.

3. Clean the axle shaft

Use a clean rag or paper towel to wipe debris off the axle shaft, to prevent the new wheel from binding.

Tip: Don't apply oil or grease to the axle, because dirt sticks to these lubricants.

4. Install the new wheel

Install the new wheel on the axle and secure in place with the nut. Attach the hub cap, if there is one.

5. Lower the mower

Remove the block of wood from under the mower.
