I was just about to start a new thread about how well the BX2370 dug today. There is another thread I started about my sub-soiler and it's WAY overkill, made for a full size tractor. 6"x1" main shank. Anyhow after a little trial and error I have it working excellent. I have hard dry clay with lots of rocks, quite a few a foot or so in length. 5 passes next to each other with the sub-soiler to get the width then the bucket with a tooth bar. I couldn't believe how much and how easy I was moving dirt with this little tractor. The sub soiler is the cat's meow. I still have to try smaller shear bolts in it until I get one to break. For now I just go slow as to not hurt anything. The dealer threw the sub soiler and the tooth bar in the deal, but from what I keep reading, I'm really thinking of getting a Pirahna, especially for tearing out small trees and brush. Still again I'll say the sub-soiler kicks butt! Oh, also for the sub soiler, out of some angle iron, sharpening one edge then bolting it in place of the normal cutting tooth, it cuts through roots that I couldn't budge before. A happy tractor day for me.
