To turn off my JD 4045, I push a red button. Just curious: how that's accomplished, cutting off compression?
Seems more likely/simpler to cut off fuel. Do you hold it down until revs stop?
Nice looking panel, BTW.
I would guess fuel cutoff. What does your manual say?
You could check the wiring diagram at the back of your 1/2" thick manual to confirm whether the switch is wired to a power-on or power-off type solenoid.
The old decompression type pull cables aren't used much on newer engines.
With electrically remote controlled "mechanical" engines, a solenoid puts fuel pump to zero fuel delivery position. Exactly same operation as pulling the stop cable on earlier versions.
With "electronic" engines, stop command does the same thing, ecm uses injector control to achieve it.
Aaahh! I'd rather spend the time doing something more rewarding! The engine starts and stops on my command. That's good enough for me. Was just curious!
Well, Mark, you did ask, and to sum up, you got the correct answer right there, from stone beach...and several others.
