Kill Switch

[thecoopers]

We are considering purchasing a 3 point hitch implement that recommends hooking up a kill switch on a string that can be pulled if there is a problem.

Does anyone have an idea how that could be done on a B2920?

What are you looking to purchase that requires a kill switch?

Hello Coopers. I am afraid that like Eric I am a bit confused. It would help if we knew what equipment this was to be used on. Dusty

A kill switch would have to be for something electronic and I cant think of a thing that hooks up to a 3pt hitch thats electronic other then a generator, but that makes electricity, not uses it.

Might be a wood chipper. I can see having a dead man on that, but it would be pricey. If it was pto driven ithe dead man switch would also have to activate some kind of braking system. Dusty

Agree with above. More information needed.

It would have to be an implement or device that is being used while one is off of the tractor. There are not many of those. A water pump, wood splitter, or chipper (as mentioned) come immediately to mind.

An electronic kill switch doesn't work very well on a diesel tractor. It would have to be wired into the ignition to activate the fuel cut-off solinoid or somehow activate the solinoid independently.

With Kubota's overrunning PTO system the implement would keep rotating for quite some time especially if a flywheel was involved. The safety in that circumstance is not so much.

Well not we just sit and wait until we get more info, cause we havent heard a peep out of that guy who posted it!

I was thinking the same thing

Well, here I am finally. Actually life has been busy and I forgot about the post to the forum. Sorry.

I am considering the purchase of a wood splitter like the one listed on Hycrack.com.

I would be off the tractor working in the back and thought that it would be a good thing to have.

Wouldn't there be a way to just kill the engine?

Well, I don't know anything about B2920. but my B7510DT has ignition switch to "OFF" position to kill the engine. It has engine shut off solenoid built in.

So in my case, I could connect kill switch to ignition switch and I could shut off the engine that way.

I hope you have that too.
Any how, how do you shut off the engine nomally? As turn ignition switch to turn to "OFF" position? or have to pull the lever to shut the engine off?
In any situation, you might have to build one of those kill switch yourself though.

Good luck on that.
Safety is first over anything. Good thinking.

Joe.

I watched the vid from Hycrack. The rope is made for a pull type fuel shut off. Your tractor probably shuts off with the key. I would be surprised if they did not have a setup to be used with a key type set up. Maybe some thing like what is used on a snowmobile. But neither of these is a true dead man switch. A dead man switch ussually involves a braking system that stops the machine the instant you hit the switch. I myself would not bother with a true deadman switch. The machine seems pretty simple and safe to use. Good luck and keep us posted. Dusty

Although my woodsplitter is a stand-alone gasoline driven type it does not have a kill switch. On the split stroke the lever has to be held down so releasing the lever kills the movement of the cylinder. On the return stoke it is held by a detent but I can't think of a time when you would want to kill the engine.

What circumstance is there that the engine needs to instantly stop?

 

[thecoopers]

Yes, the tractor turns off with a switch and key. So maybe there would be a way to wire another switch that could be activated with a pull cord that would shut down the tractor if there was any type of a problem. I really wouldn't want to drill any holes. I will have to take a look.

You said:
"So in my case, I could connect kill switch to ignition switch and I could shut off the engine that way." Maybe I can too!

Thank you.

I believe that is the case.

You mentioned that a snowmobile has a kill switch. Maybe I could check with someone that sells snowmobile parts. It will have to be have to be online; as we live in Tennessee!

Thank you.

The woodsplitter that we are looking at is not a hydraulic one, but an screw type splitter. I just thought, even though I don't really see a safety problem with it, it would be good to have a kill switch.

Ah, yes. I have used those screw-type splitters. Very dangerous indeed so a kill switch is a good idea.

Mine was bolted to the rear axle of a truck. It actually worked fairly well. However, there was a kill switch that attached to the coil. It had to be used more than once. My advice is to definitely install a kill switch somehow.

The fuel cut-off solenoid would be a good spot to attach an electronic kill switch.

If you have a lever to manually cut off the fuel in case the solenoid somehow fails then a strong string to that would work. That idea may have already been mentioned.

A kill switch is a good idea. I would place it between the fuel cut off solenoid fuse and the solenoid. wwwBoatSportAndTackle.com has a kill switch and lanyard for 'bout 13 bucks that may work for you.. Safty first, as they say.
