I bought one of those thinking I was going to mount it on the backside of the ROPS, but that didn't work out. I wound up cutting the mount off, welding a piece of square tubing on the backside, and bolting that tubing to a couple of existing holes on the fender. The chainsaw bar sits inside of the fender and the motor sits on top of the fender. Might not work too good on a BX though.
I like the idea of the Byte Tyte saw scabbards. made of aluminum, a softer metal than your blade so it won't dull it, and holds by clamping on the bar. It also has no holes drilled so you can do you own mounting as your need it. They make them in different bar lengths or the universal one like I have on both sides of my carry-all. Didn't want or need it on the tractor all the time.
