Don't.
It's there for a reason.
You should never by pass any safety sensors on your lawn mower. BUT :for testing your brake sensor you can try taking the wires off the switch that is hooked ether at the back of the peddle or on the linkage and join them together .That should bypass it until you get a new switch.
Check your seat safety switch. Just a guess..
Yes pull pto up when pressing reverse pedal pto remains engaged. release when moving forward.
I believe it is threaded into the transaxle at the rear of the mower
The time delay module in this particular model can only be bypassed by an authorised dealer for safety reasons. The part exists to prevent electrocution, so it is prudent to adhere to safety regulations.
I had a problem with the break switch this spring. Took both plugs off the back of the switch. Hit them with contact cleaner, now it is fine. Brian Butts
It has 16 forward and 8 reverse.
on the brake
There is no light switch. The lights come on when the tractor starts up.
I have a model 950 tractor that also uses the same heat sensor switch - ch15516. As far as I know, you cannot use anything but this john deere part. It is about $35 a your nearest Deere dealer.
See if you're getting power to the small wire at the starter in the start position. If not you have an issue in the safety switch circuit. it comes from the key generally. How are the battery cables?
Operators safety switch, busted belt, or something stuck in deck NB Don't try any maintenance unless you KNOW that ignition is impossible - you need to retain all your fingers!
