The rake looks to be in pretty good shape, the gears in gear box look good, I turn it and looked with flashlight and none broke however it didn't work at first, the gear on the driveshaft needed to be pushed in about 3/8 of an inch and I put a spacer in there to hold it and seems to be ok. The drive shaft is in good shape and I greased the u joints and other points. Both wheels drive and click good. The speed doesn't seem to stay consistent, not sure why. I put new cables on it and height adjustment works good. Includes original wheel. The drives shaft can be easily removed and can be towed home that way. Video of it working.
