Need disc harrow to work better
Yesterday i hooked up my 8 blade disc harrow to my craftsman tractor to work on a small piece of land in my back yard for the first time. My ground was still damp from rain the previous day and it has some ground cover on it that had been mowed down a week ago. With the disc harrow by itself it wouldn't even hardly mark the ground. I then put on two buckets of 60lb weights on it and it started to dig in. The problem is it would only cut with the two inner disc's. Is there something wrong here? I have heard there is a mod to do to it to get it to cut better but they were very vague as to how to do it. Any ideas?
