One Drive Wheel Stopped Turning on My Self-Propelled Lawn Mower

 

Today’s self-propelled lawn mowers either have steel or plastic drive gears. The steel gears never seem to wear out but their spring loaded woodruf keys that are on the axle can rest and stick in place. When this happens, one side or both can stop working.

If you have a plastic drive gear on the wheel, it can wear out and stop pulling the drive wheel.

In either case the drive wheels will need to be removed and the drive system inspected. While you are at it, inspect the drive belt for wear. If it is loose or rides deep in the groove, it is time for a replacement.

Carefully inspect the drive gears to make sure they are not missing any teeth or are worn out. Grass clippings can also get into them and fill the grooves between the teeth. Clean them out good and replace any worn parts. Also check the drive shaft on models that use the spring and woodruf key. Clean out the slots and ensure everything is dry and free of grease and dirt.

Self-Propelled Lawn Mower Will Not Move Backwards

This is a common problem with self-propelled lawn mowers. Over time the mower does not want to go in reverse and the wheels lock up and you must drag it in reverse.

Let’s think about the environment that a mower operates in for a minute. It is a dirty and dusty one and this dirt and dust permeates everything. The dust will enter into the rear drive axle of a lawn mower and begin to build up inside it. This dirt becomes a grinding paste that wears on the plastic inserts in the wheels. It will also build up inside the spring loaded key that is located on the axle and prevent it from moving.

So as the dirt and dust build up, it freezes the mechanisms that allow the wheels to move in reverse and that is often the issue.

You can pull the wheels off the mower and see if you can clean the axle and drive mechanism to see if it helps, but most of the time you have to remove the axle assembly and replace parts.
