I received this tiller for free with a snow plow and snow blower. I took the tiller apart because the bottom tiller shaft had a good wobble in it so I thought bearings? After all that the nuts had loosened up and were causing the wobble. I replaced all 6 bearings, they were expensive and difficult to get off. If you attempt this, the most difficult parts were getting the tine tubes off the shaft and those lower bearings. My tiller was in decent shape otherwise to begin with.

This is the method I used to get the tine tubes off the shaft, I bolted a gear puller up and a piece of round stock to push on the shaft(inside the tube). I heated it cherry red and used an impact gun and it fought the WHOLE way. Be careful with the heat, I stretched that thick wall tubing so only put heat where you need it. I used a press to get the tube semi straight after. I guess I will not be adding the extensions on this one...
