I was getting gas at a local station this morning and noticed a massey ferguson 1020 on a trailer at the next pump over. The tractor had what appeared to be a mid mount mower but everything attached to the rear 3 point hitch and was powered by a drive shaft connected to the rear pto that changed over to a belt to send power to the blades. I was distracted by a phone call before I could take any pictures or catch the owner before he drove off. I haven't seen one of these before. Does anybody know more about them?
