Another thing, I had just stopped operating my tractor for a moment to talk to friends that just pulled up with their 2 boys; turned it off but left the FEL still about 2' off the ground; was only stopping for a moment I figured, didn't really think consciously much about it. Their little kid, about 2 years old wanted to get on it, so I helped him up onto the seat thinking it would be fine, heck it's turned off after all. The first thing he did was yank every single lever, steer, shift, horn, the works. Had he pushed the FEL lever, of course it would've gone quickly onto the ground; push hard enough & it goes into float, aka free-fall onto the ground ... & his brother could easily have wandered under there. Then I'd have had to actually re-start the tractor to lift it off him, & hope that it hadn't completely crushed him - I had my grapple-bottom bucket on, which seller said weighs about 500 lbs, & that doesn't even include the loader arms, or any possibly head of steam. Even for that moment, I now wish I had set the FEL on the ground.
Fortunately this was a learning experience not the hard way, but certainly could have been.
