Rototiller jams the whole tractor shut done?

Is your tiller a Reverse Rotation? Locking up on 5"+ rocks is a common thing to happen on this type of tiller. Setting slip-clutch properly to allow time to shut off PTO is very important. It may require setting slip-clutch with a little more slip than normal to give time for hydraulic drive clutch on a B3030 to be disengaged.

I did forget to mention, on the outside flanges I also removed the tines facing outward to prevent rocks from jamming there.

Till for thirty feet, stop, pick rocks, place in bucket and till for another thirty feet.
