Replace the wheels and axle shaft using the manufacturer-approved replacement parts.

Instructions

 Warning: Undertaking repairs to lower lawn-care equipment can be hazardous. Use the proper tools and safety equipment noted in the guide and follow all instructions. Do not proceed until you are confident that you understand all of the steps and are capable of completing the repair. Some repairs should only be performed by a qualified technician.

Step 1: Elevate the mower

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. 

Use a block of wood to lift the wheels off the ground.

Step 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.

Step 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.

Clean the axle.

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

Step 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.

Step 5: Lower the mower

Remove the block of wood from under the mower.
