I kinda want a small dozer too.
My current FAVORITE accessory has been the 4 foot brush fork (bolted to my bucket). It's saved SO much time doing my burning. I can make a HUGE pile of brush, logs, sticks on the brush fork, then drive the BX over to the burnpile, and drop the whole thing ontop of the pile. And since they are 4 feet long, they move FAST when you rotate the bucket, I can 'flick' burning logs ontop of the pile. And reach over the far side, pull logs back ontop of the pile. Also I need less burnpiles too, because the travel time is minimal. For anyone doing slash burning I highly recommend a brush fork.
