After using both a standalone trencher, and the backhoe on my bx-22, I will never use a trencher again. The soil here is moist clay after you go down about 12", and the trencher kept clogging up with clay. It was awful. I told myself the next time I would use a backhoe. Now I have my own, and it's wonderful! No more clogged trenchers. Backhoe's rule!
