The mower has a number of issues:
The cables for drive and start are both broken. The drive belt is flabby. The transmission pulley will turn in one direction. In the
other direction it turns about 3/4 of the way then will not turn after that.
I took the transmission bottom cover off and saw that the when the worm turns one way two other gears do not engage.
When it is turns the other way 3/4 it engages two gears. On gear gets pushed into the other as the worm turns. When they lock
together the turning stops. Something is frozen. I think it is the axle to something else that is frozen.
At that point I was stuck so started taking the wheels off. After I took the wheel nuts of neither wheel would pull off.
I spread the back wheel cover to look inside. There was water and dirt in there. The water has drained and I got most of
the dirt off. I thought the dire may be between the wheel gears and drive gear and locked. I hit the drive gear a few time
with a screwdriver and hammer but it would not budge. I did that on both sides.
From the drawing it looks like there is nothing holding the wheel on other than a single bolt on each wheel. The way the
wheel acts is like the hub is rust frozen to the axle. But I think the hub is plastic. I can't see a metal sleeve in there and
don't see one on the drawing. So I don't know why the wheel just does not pop off. Being frozen is a puzzle.
Both are frozen solidly. Give that they should come off easily I think I have missed something. Any help would be
appreciated.
