Same... 99.9% of the time. Then there's that 0.1% who forget to put their shifter into neutral and run themselves over starting the tractor from the ground.
Two personal experiences:
1. I used to build hotrods, street/strip cars, and off-road trucks. We had a party at my house one night, and some random guy was sitting in my street/strip car playing with the Pro Stick, as he'd never seen a manual valve body transmission or a pro stick. I'd never gotten around to hooking up the neutral safety switch on the pro stick, and hadn't noticed that he'd left it in first gear when I went to start the car the next morning.
Unfortunately the front end was up on jack stands, I'd been in the middle of some exhaust work, and this launched the car off the stands. One punched up thru the passenger side floor board, the other went right thru the transmission pan. Thankfully, nothing critical in the transmission valve body was hit, but the car almost crushed a buddy of mine up against the wall of the garage, as it teetered toward where he was standing next to the car. And of course, I'd just bought myself an extra week of floor pan and transmission pan repair, and a concrete floor that never smelled right again.
2. A friend of mine was mowing on his ZTR, when he stopped to take a drink or adjust his hat, right atop a yellow jacket nest in the ground. He started getting stung by the swarm pouring out from under the mower, and went to jump and run. Unfortunately, his boot lace caught on the mower deck lift pedal, causing him to trip and accidentally throw one of the ZTR levers into reverse as he tried to catch himself.
Because he'd disabled his seat safety switch, the mower just kept running, going in circles in reverse with the blades still spinning, dragging him along behind it by the heavy-duty shoelaces on his boot. He got dragged over that yellow jacket nest, probably a few dozen times, before a neighbor saw what was happening and ran over to jump onto the running mower swarming with hornets and shut the rig down. Both ended up in the hospital, my buddy having literally hundreds of stings and in shock from the venom load.
So, think long and hard of the stupid and ridiculous things that can happen, when safety switches are left disconnected or intentionally defeated!
