I've had my tractor and Bushhog for about 3 years now. I use the BH to cut back some trails at hunting camp about once a year, so my experience in hooking up to the tractor is limited. It always seems to be a challenge to get the cutter's shaft collar on the PTO shaft of the tractor. Usually wish that I had 3 hands if I'm doing it alone. Any secrets you guys use would be appreciated.
