I have been looking for a good CAT 0 one row cultivator for several months with no luck. I have been looking at a light duty CAT 1 cultivator at Rural King. I am considering modifying it to a CAT 0 3 point hitch to use behind our 430 John Deere garden tractor. Weight shouldn't be a problem at a little over 200 pounds. Can anyone give me a reason I shouldn't do this?
