I have a 430 with a model 30 hydraulic tiller mounted on back. The whole machine is new to me, so I have some questions. I tried breaking sod in my yard with it, and when I even touch it to the ground it tries shaking the tractor (430) to pieces!! Actully it doesnt shake the tractor so much, but the tiller itself bounces around and does all kinds of shaking. I havent had a chance to try it on an existing garden. I have it set up so the tines rotate backwards compared to the direction of the tractor. What tips can you give me for tilling and what to expect. Can I tear up my tiller or tractor trying to break ground with a tiller??
