I have a model 10864 with rear drive. It is about 6 years old. The rear drive wheel seems not to disengage. In addition, the other rear wheel has been locking up while in use and engaged. Any thoughts on the problem and how to fix? Thanks!
I would say you either have worn wheel drive gears or the teeth in the wheels themselves are worn. Also may be that the drive gears are frozen on the shaft. If the wheels wobble it could be the wheel bushings are worn. Could be a combination of all of these. Is your model 10684 not 10864?
Have you pulled the drive wheels off and checked the teeth on the wheels and drive gears. Drive gears should spin freely.
Not yet but will do. Many thanks.
