Spoken like a true OSHA fan. Most interlocks of this nature are lawyer-driven - by the Nanny state and/or corporate lawyers - looking to stay one step ahead of litigious owners. FWIW, there's another "old saw" that says interlocks eventually defeat common sense. Do you not find it ironic that one of the initial steps in competently isolating an electro-mechanical problem is to bypass the associated interlock(s)?

My understanding of the English language is sufficient to know what irony is.
Bypassing of interlocks as a TROUBLESHOOTING technique is quite independent of disabling them for *** scratching convenience.
Read the stats, we DO need protection from our own foolishness and we need to NOT disable such protection.
Duhh, but that stuff is for fools and we ain't them, right ?
(foolishness, moments of inattention, carelessness, unexpected factors, call 'em what Ya will, factors combine and people get hurt.)
WRT operating a
chipper or other PTO implements when stationary and off the tractor; On INTELLIGENTLY designed and implemented tractors the seat interlock is logically OR'd with neutral AND'd with brake.
IOW if you are in neutral and the brake is applied you CAN get off the seat (to operate the
chipper, scratch, whatever else)
Ooops, Sorry - my bad.
This is a JD sub forum - "intelligently designed and implemented" are my working assumptions from elsewhere.
Regardless, the O/P may want to think this through to implement something OTHER than just a simple short circuit.
It takes THOUGHT and maybe a bit more time, but the neutral and brake switches are there and COULD be used.
