My uncle (in his 70s now) started working at an agricultural contractor when he married my aunt and moved into our area. They loaded the muckspreader with a PTO driven, pull type excavator/backhoe driven by an MF TEF.
Once he stepped over the PTO shaft to the other side, his coveralls got entangled and he had to fight the PTO: He could keep his thingies away from the shaft by putting his hands on his knees and holding on: His boots were pushed 6 inches into the muck, he bit his fake teeth in two, and luckily, the little Fergie stalled after a minute or so....
The little fergie did the job because the slightly more powerfull McCormick that was otherwise used to drive the digger, was that day on another job.... Speaking of luck !
