Disabling a seat switch?

I have an 87 RX75 JD lawn mower. I mow on hilly uneven ground and I slide around on the seat. When I slide over to far the mower shuts off. I tried to by pass the switch under the seat but when I do the mower still starts and runs but it won't let me put it into gear or engage the mower blade. Its like it has a safety switch somewhere that checks on the seat switch. What do I have to do to get rid of the seat switch and keep the thing running? Thanks

When your kid or your neighbor or somebody else loses a few toes you'll sing a different tune.

No one uses the mower except myself. I attached a bracket now that holds the switch down. Now if I sell or loan the mower out I can take the bracket off and it will be legal again. The way it was, I couldn't even use it because it was allways shutting off.

They would be looking for a lawsuit and a lawyer.

Randy , let me tell you one way I've seen bypass the seat switch. And it worked very well. Actually , the switch wasn't bypassed. It was fooled! I just bought a nice used Cub Cadet garden tractor , and wanted the seat switch to work when my wife was mowing the lawn. So , I flipped up the seat in order to evaluate the problem. There was no problem. The previous owner had pushed down the metal plate which activated the switch. Then put a pin through the post(one on each side)so that the metal plate could not come back up. In other words , the system always thought someone was on the seat. Very clever , I thought. I pulled the two pins out , allowing the metal plate to spring back up. The switch now works great.

Those mowers have a backwards seat switch. If you carefully inspect the connector, you'll find a little spring loaded piece inside the wire side of the connector. Jumping the switch the way one would on other mowers doesn't work on this model. Just unplugging it won't work either.

Most riding mowers have a seat switch that is normally open when the operator is off, and closed when the operator is on the seat. If you take a continuity tester to the seat switch on yours, you'll find that its open when you are on the seat, and closed when you are off.

I've by-passed this thing on these models several times for diagnostic purposes, or for my own use. Its really simple.

Hi Randy,
Had the same "problem" with a Husky 2148 that was purchased new this past year. The Husky has a switch compression mechanism located under and within the seat pan. I simply tightened the adjustment screws on this until the switch was "made" without any weight in the seat. Like you, I had first tried to jumper the switch but only got the mower to start without other functions.

I assume there are two wires going to the seat switch? If so the switch either makes or breaks the connection of these two wires--it can only do one or the other.

Remove the wires from the switch. Does it now work like your sitting on it when you aren't? If so the switch broke the connection when you are sitting on it and your good to go just leave the switch disconnected.

If not the switch made the connection between the two wires when you are sitting on it (more likely) and you need to somehow splice these wires together all the time. There are many ways you can do this. If you are lucky like me you can make a jumper from a U shaped piece of wire and wedge in the connector instead of the switch. I can pull the jumper out any time and plug it back into the switch to sell the mower with all safety features working.

Add some weight. Wheel weights or load the rear tires. The seat safety is there for a reason.

You may find people giving you clues like if this worked like that then blah blah blah, they are right no one will directly tell you how to bypass a safety issue, I have found that the safety switches are usually active when they are in a closed contact state.

You just need to gain some weight.

By laws of the federal government and the CPSC, the only one that can unhook or bypass the safety switch is yourself, and no one can legally explain to you how to do it.

What are you talking about? Who is the CPSC? Is that CCCP?

Mark

(If I want to talk about the little thin metallic jumper I found embedded in the plastic of my seat connector that didn't belong in there after disconnecting the harness, and having to jumper the wires off my back up beeper that didn't belong in there that's my business.

If I step off my tractor and get my foot tangled up in the blades cause my seat switch is "broken" and won't kill my mower, that's my business too.

What we need is more big brother worrying about the nebulous stuff, keeping our minds occupied, and letting the country (the big stuff) go to HE!!).

We're not talking about EPA pollution and disconnecting your air pump and all that.)

Mark, The CPSC is the consumer products safety commision.
A office of the federal governmant set up to protect you from yourself and to protect manufacturers from lawsuits.

Thank you sir. I like the "protect me from myself" part. Kinda goes hand in hand with a "blameless" society.

If I sound sarcastic, I am. I'm from the old school where you mess up you get your butt busted and are responsible for your own actions.

As I recall, we didn't hear much about lawsuits until the Fed said lawyers could advertise.

Mark,
I am sarcastic about the whole shebang, I think it is the biggest crock when the federal government thinks they have to protect me from myself.
The problem is that people are so careless, we are in a we need to blame someone for out stupidity society, these laws were enacted. The general public did not hear much about lawsuits of this nature, but, I being in this industry for several years have heard about manufacturers being sued because somone put their hand under a running mower, and got their fingers cut off. and WON big settlements. Mark, I am with you on this, I was taught if you get hurt from stupidity, you learn a lesson, pick yourself up, brush off and then go at it again, just a little less careless. But money hungry people, looking for a easy way to get money, along with greedy lawyers has made these kind of laws necessary for the carelss people of the world!!!! Makes me sick, all this does is makes my cost of doing business to skyrocket, then your cost of my product is higher, then everyone says I am overcharging for my product. Where did the decent, friendly, laid back lifestyle go, I sure miss it.
Jim

I'm allready 30 Lbs overweight. I have an old 1973 JD model 56 mower with no seat switch and it hasn't killed anyone yet. Maybe someone can email me with the solution with no name attached.

If the 2 wires that go to the switch are connected together does the mower run. Mine will.
