Well, my experience with both the BX, and B have been positive. The B is a more laid back tractor, and does a lot of work at lower RPM for every day chores like loader work, etc. I found the BX to be extremely tough, but running it at higher RPM for everything made it sound, and act "busy" to me. Evern my Simplicity Legacy with the gas engine seems milder, quieter, and less so. Still, the BX is the Swiss Army knife of homestead tractors, especially if you need something that you can mow with as well as do the tractor work. I miss mine sometimes, and wish that I had gotten a mmm for it when I had it.
