Been running it 23 years to do all manner of things, tilling acres with rototiller, pulling an ancient ground drive sickle mower, runs a square baler, pulled logs off a mountain side, even pulled an old walking plow a few times with someone behind to guide the plow.
Just don't run heavy load consistently on the high PTO speed. I was running the tiller on high and wore out the gear in the transmission that runs it, same gear runs 3rd gear. Running a large sawmill edger was also a bit too much, it did it for awhile but finally popped a tooth off the final PTO gear. Yeah, I've overworked and abused it, and it's put up with most of the excess.
