How Does a Safety Switch Work?

How Does a Safety Switch Work

Well, if we put the safety switch’s work in simple words, it is a mechanism that turns off your engine and kills the main power in case of an electrical issue or threatening situation. Safety switches can detect the tiniest differences in voltage and electrical wiring current.

If your tractor is facing problems like exposed wire, short circuit, or faulty appliance, a safety switch is the one that comes to the rescue. It minimizes the risk of electrical shock, lethal electrocution, and other personal injuries.

Safety switches typically serve two purposes, killing the running engine and disabling the starter engine. If your tractor fails to meet the safety requirements, the switch will automatically disable the starting engine, and this won’t let you start or run your engine.

Eventually, you won’t get any injuries while driving a tractor if the safety switches are on. Multiple safety switches in a tractor interact with different parts of the tractor, making mowing safer.

You will need a multimeter to help you check for continuity, which will be used to check whether there is a connection between two terminals. 

The safety switches should have continuity in one way and then if you depress or release the safety switch, you won’t have continuity. It is like an On/Off thing.

Step 3: Connecting the Meter with the Switch

Now, connect both the leads of your multimeter with the safety switch, and put the points on each side. If you have continuity, you will hear a sound from your multimeter. 

If your multimeter makes any sound, you have a full connection, and the safety switch is working fine. Next, depress the seat button with your hand and turn it off.

How Do You Know If the Seat Safety Switch Is Bad?

How Do You Know If the Seat Safety Switch Is Bad

The seat safety switch shuts off the engine when the driver gets off the seat. But if you see your tractor is still operating and the deck is still engaged even after you get off the seat, switch malfunction is possible.

If you notice your tractor is not automatically killing the main engine off while you get off your seat, it’s safe to assume that you have a faulty seat safety switch.

How to Bypass Seat Safety Switch on a Tractor?

Although we don’t recommend bypassing or disabling your tractor’s seat safety switch. But for those of you who want to do it or need to do it, you are bringing down the safety standards of your tractor. 

So, if you are disabling the safety switch for troubleshooting purposes, then you are good to go. So, let’s take a look at how you bypass a seat safety switch in a tractor.

Step 1: Detaching the Connector

Detaching the Connector

First of all, find your safety switch; you will see it beneath your seat. You will see a connector attached to the safety switch. The next thing you need to do is to disconnect the connector from the safety switch. Just pull it down from the safety switch box, it might take some time.

Step 2: Disconnecting the Switch From the Connector

Disconnecting the Switch From the Connector

You will see a four-pin connector. Some tractors have a three-pin connector attached to the seat safety switch. 

Now, for checking, disconnect the switch and just leave the connector not plugged in and try to run the tractor or mow the grass with the parking brake disengaged. It will turn off the engine as soon as you disconnect the brake, whether you are sitting or not.

Step 3: Pulling Out the Pins

Pulling Out the Pins

So when you are done with the disconnecting, you will see little bars on the connector that come down and touch the pins grounding them out. 

That’s how your tractor knows there is nobody on the seat. People usually use toothpicks or anything and try to lift the pins up, so it doesn’t make any connection, but we got a better idea.

Check the other side of the connector, you will see a notch and through that notch, you will see a metal tab. Now, you have to take a straight pick, put it through the notch, and push out the pins. Grab a pair of needle nose pliers and pull the pin out of the connector. There you go, you just bypassed your seat safety switch.

The pins act like a spring; when you get out of the seat, it comes down and hits all those terminals of the switch. Thus, causing a close circuit, and your tractor shuts off.
