I have aquired the schematics , my local John deere also does Kuhn, they don't have or are available any more, the parts that make my tiller completly a piece of junk.

I need the steel cage that surrounds the shifting forks in the transmission,pt. no. 522-312-00 and the shifting guide to keep the shifter in position, pt. no. 522-920-00

The ser. no is 740420

If any one out here has knowledge of a tiller grave yard or somthing , every ones help is greatly appreciated.

Yes it has a 3 speed trany, It would work great for our soil conditions, low range to break it up realy well and high range for completly tilling it up for gardening and not have to break up all the large dirt clods usaly left from a single speed tiller.
