Default Overriding mower safety switches

John Deere G110, has a safety switch under the seat. Does anyone know how to bypass so that I can get off to move a stick or dog toy without having to turn the mower off?

My father in law used to have his wired to where he could switch it "off" if he was mowing and "on" if his kids were riding, but that was 25 years ago and he sold the mower before I could reverse engineer it.

Also, any help bypassing the "reverse while cutting" button would be great too, what a PITA.

PM me if you want, in searching the internet, I have not found the solution I am looking for, just a bunch of "well, if X found out that I told you, I'd have to kill you".

And before it gets brought up, yes, I know that they're there for a reason, but if it's any comfort, no one is allowed outside while I am mowing.

Thanks

I'm not sure on that mower but its probably a contact switch. When the seat has pressure on it, it completes the circuit. If thats the case just splice the wires together from both sides of their switch (somewhere under the seat). Thus the circuit will act as if you are always sitting on the seat.

Using the same principal look for the switch for the reverse kill. (it should be somewhere so the shifter makes contact when put into reverse).

Having worked at a John Deere dealership (several years ago), I can tell you Catfish is right on how you bypass the switch. I've seen it done a few times. I can also tell you of several toes and feet that have been left attached due to the switch being active. It's meant to protect the operator of tractor not someone else in the yard. A customer once fell off his mower while mowing a fairly steep bank and managed to get his foot under the deck. The switch killed the engine and he felt one of the blade pass across the toe of his boot once, then it shut down completely. Sliced his shoe a little, but no other damage. He brought the boot into the dealership to show everyone. He'd been in a couple weeks before looking for instructions on how to bypass the switch. In the end, he was glad he was not given the instructions.

I believe setting the parking brake bypasses the seat switch.

The reverse button only needs pushed momentarily and then you can back up and cut all you want. Or just pulse the reverse pedal to back up the needed distance and then continue forward. I to find it a bit annoying, though.

If you get your feet cut off because of my instructions; don't come running to me.

Seriously, I'm assuming your a competent adult and understand the risks involved. Be careful out there.

I did it on an old Murray that I had. The switch was old and corroded, so worked intermittently, and would sometimes kill the mower while you were riding it. A time or three of that and I just cut it off and went on. It's there for safety, though, unless it's absolutely necessary, you ought to leave it.

My new mower has it, and since it works properly, on it stays. If I ever turn the thing over, I'll be glad I left it, I'm sure.

actually, I'm thinking about putting a toggle in so that I can have it "on" while I'm mowing, and then flip it to "off" when I want to get off. I want the safety AND the convenience. I'm assuming that's possible, but it's been 2 years since I looked at the safety so who knows.

no, I would never come after anyone if I got hurt from doing something like that. People who play the "lawsuit lottery" piss me off.

Thanks guys






edit: tried a paperclip to see how the loop operated, success.



trimmed the clip down real neat and taped it for now.

now to try to figure out how to get my "toggle" idea to work.

So the mower circuit goes through the switch as well. That's because the blades are supposed to stop it you leave the seat.

Try a paperclip in the other two holes.

1. Why not just tie the seat down so when you get up it stays down??
2. A guy overode the reverse shut off near here and a 5 year old boy was run over as the guy was backing up and cutting around a tree, looking left, the child came up from the right. He's still fighting for his life.
I had to tell ya.

I forgot to comment about this earlier. The mower has a 54" deck, so hopping down is a little awkward to begin with, disengaging the deck before getting off is 100% mandatory if you ask me, so that shouldn't be a problem.

I tried that once, not enough force, little missy is touchy. I weigh 200+, and if I shift my weight too much to one side, it kills the switch.

yeah, I really thought about that being that I have two little ones. In reality though, having to push in a button while you're turning around doesn't solve the issue of the child running up from the other side. My daughter knows that she is not to come into the yard while I mow unless mommy is with her, but I know that's not 100% since she is only 3, so the reverse switch is more of an afterthought that I thought I'd get an answer for now and save it for later.

For now, I reattached the seat switch, and just ziptied the button down. I'm going to pop the switch casing open to see how it works and try from there. I tried another clip in various combos in the other holes and got nothing, one combo actually killed the mower, whoops.

Are you saying that mowers now stop the blades when in reverse? I have the kill switch under the seat but do not have any thing for reverse. (Not that I want it). Just curious.

My Ingersoll has a bunch of those little safety switches... zip ties are your friend.

someone on another board mentioned the same thing, I never knew that, I'll try it. Heck, if it works, simplest solution yet!

yes. (On mine) if my mower deck is engaged, I have to push a little button on the dash when I first push the pedal to back up or it kills the mower deck and engine.

I see their point, but like I said earlier, it's really just overkill.

As everyone, including yourself, has said already, it's there for a reason.

It seems like overkill until the time it saves a life or prevents injury. If it were bypassed and someone got hurt, you'd never again think of it as overkill.

A friend of mine is an auto electrician, he does work for a company that runs plant machinery and haulage trucks, as well as a workshop specialising in performance cars. One guy came to him with a 25' 6x4 box truck. (i'm talking 12-litre diesel, this thing is big) and said he wanted the back-up alarm removed.

He was asked why and told my friend that it was so loud that it annoyed him. The reason it was so loud was it had to be audible over the sound of the engine revving up while the truck was reversed. In the end my friend refused, and the guy cut the wires himself.

Some time later, he reversed and killed someone who didn't know the truck was reversing, the driver never saw them, and they never saw the truck as it was behind them.

This is not an attack on you, merely me relaying a story i was told as reason to keep safety precautions.

I'll bet the manual explains the safety switches and what functions with what. Yes the parking brake should bypass the seat kill switch and also the parking brake should kill the blades (if electric clutch operated). Thats how my Great Dane zero turn works, and also how a JD Sabre riding mower a friend has, works. Darn easy if you ask me, stop, set brake, get off, get back on, release brake, continuing mowing...... no safeties bypassed, no one harmed in the making of this post.............
