All these safety switches; society assumes we must be protected from ourselves. The people making these decisions likely have never farmed or been on one.
The people making the decisions are protecting their companies from liability lawsuits. They really don’t care about your experience level or confidence or whether you kill yourself with their tractor. They just need to be able to be on the witness stand and say their machine met mandated OPE standards when it was shipped. If their switch malfunctions in a dangerous way, they’re liable. Fail safe operation is always finicky and contrary, no matter what it’s used for. If you disable it, your survivors get jack diddly when the machine kills you.
Personally, having had a rollover that pinned me under a 400 pound running mower such that I couldn’t reach the key taught me a valuable lesson. All it took was slightly wetter soil along the edge of a ditch to make the mower slide off the edge and I was upside down before I could blink. I still remember that sound of blades spinning upside down. I make sure the safeties work on all my machines now. That mower has long since been retired and replaced with a newer model with more safeties. I check all of them annually. Replaced the seat and had to reuse the existing seat switch. New seat is much firmer than the original, so I had to use a bit of ingenuity to make it work. Bottom line, I was not going to run the mower without knowing it would shut down if needed. That experience is not one I wish to repeat. I was somehow uninjured save a few scratches, bruises and strained muscles, despite the mower pinning me underneath. It took some serious strength to get it off me. Fortunately there was no water in the ditch after a heavy rain the previous day. I could easily have drowned. Biggest injury was my ego thinking I didn’t need a seat safety. I don’t think that now. Not advising nor criticizing anyone’s opinion, just relating a very scary experience.
I have a Kubota LX2610SU-HST. If I want the PTO enabled with me on the ground, I park the tractor, select Neutral, set the brake lock, raise the front with the FEL, then shut the engine down to set up the
chipper. Aint no way I’m putting my hands anywhere near that
chipper with the tractor running until I have every safety in place and checked. Then I start the tractor standing next to it on the RH side at arm length so I can get away if it thinks about moving. All I have to do is push the off-tractor bypass button for 5 seconds. When it illuminates, I walk around to the left side and engage the PTO, again at arm length away. Bob’s yer uncle. Set PTO speed and go to work. If there’s any possibility of the tractor moving, the bypass will not come on and the tractor will shut down if the pto is engaged. If I forget and leave the pto engaged when I shut down again, it will not start.
