This happened to me yrs ago, back when I had my 85 Nissan King Cab and my Massey MF7hydro.
One day in early June I was loading the MF7 on to the truck, driving it up a set of wooden ramps, started going up no problem, got the front wheels in the box, then the mower deck starts to drag, gave it a little more power, the ramps moved back off the truck onto the ground, the rear end of the tractor fell down to the ground with the front end up in the air, I thought it was going to come right over and land on top of me but instead it fell over to the left side. When it hit the ground my foot was between the mower deck and the ground.
Broken left foot and my grass cutting jobs ended, can't cut grass it you can't walk properly. Lost all the contracts I had at the time.
Always lock the ramps to the truck, it's not worth it to get hurt for not being careful enough.
Doug, at this point, you have the top ranking for personal injury pain!
