I have an older Craftsman 22" self propelled push mower that no longer propels it self. If I engage it the front tires lock up and nothing happens. Any ideas what might be keeping it from moving
Strange that the wheels lock up, they usually quit pulling. I'm assuming it's a front-wheel drive as most all brands have used this same system for years. There is a metal gear driving plastic teeth in side the wheel and the plastic teeth strip off pretty regularly. Maybe some debris has gotten in and locking one or both wheels. Otherwise if it's locking up it may be a problem with the gearbox.
Here is a Youtube video showing the gears in the wheels.
