dead mans switch?

[cnc mike]

Hello all, I'm new over here but have used this site for lots of info on making my purchase. I bought a house that was rented out for the past few years so the areas leading to the woods is very over grown. ive been removing fence and clearing the vines, sticker bushes, small trees, poison ivy, ect. today i was pushing through brush with the loader bucket teeth in the ground going towards the fence between mine and my neighbors property. i just put it in reverse when i seen all these bugs go flying. well the bugs turned out to be yellow jackets and they lit me up! as soon as i realized i was getting stung bad i jumped off the tractor and went running. i look back to see the tractor creeping backwards still so i ran back to shut it off and got stung several more times. Its an L3650 GST, I had the dash throttle set running around 2000 rpm and was in 1st gear. im glad i was in reverse because it would have went right through the fence, it was about 15 feet from running over a bunch of stuff in reverse. I'm now sitting here thinking how dangerous this is/was and how i need to figure out how to prevent a similar situation...

I'm not sure if this tractor has a dead man switch on the seat or not, it does not work if it indeed does. heres my second part of the question though, its got a backhoe with the separate seat on the back. If it did have a dead man switch or if i installed one, how would you get around the backhoe portion of things aside from adding a toggle switch or something of the sort which could easily be forgotten.
Sorry for the long winded post.
thanks
Mike

mmm....

when you get BACK on your tractor - fire it up and then move forward or backwards....then STAND UP ? will it kill the engine? If so - then the switch that you are looking for is there, maybe the rate of movement was so small that it did not pick it up.
Many of us wish to stand up to see where the bucket edge is located on very delicate work , only to have the engine stall....

most tractors (newer models) have an occupant safety switch - butt in seat and tractor works......hit bump or stand or lean hard left or right and it stalls

on my bx i can start the tractor NOT in the seat , cannot move it, double check your seat and switches and see if the switch is there or not.

as far as the BH.....mmmmm..... that situation would be difficult to work around.

Not sure on the switch and that model. how bad did those things get you? I hate yellow jackets i don't know what bugs they keep under control since a yellow jacket only job is to kill other bugs, steal, and sting repeatedly.

Hopefully you have a safety switch to prevent this again.

Found nest 3 different times this year but luckly only got stung twice. Your story hurts just reading it.OUCH!

Ouch!
I remember whn I was young my brothers and I raced up some trees.
I was in the lead.
I was also the first one down after I hit my head on a nest and was stung 40+ times!

Usually a dead man or safety switch only kills the engine when it is in gear.
So if you were in neutral and using the backhoe it would not be an issue.

Another option is to use a boat kill switch with a Lanyard.

That model does not have a seat switch.
You could add one in if you so desired.
I have a L3450GST and I happen to like the fact that it has no interlocks on the seat.

Thanks for the replies guys. I counted 15 stings, there may have been more but thats what i could see. There were 5 on my back that I didnt even feel because the ones on my neck, lip, ear and forehead hurt more haha. I got some heavy duty steroids and it made the recovery very quick.

I didnt remember seeing any wires under the seat when ive had it flipped up so im going with what wolfman said with there not ever being one on it. I'll have to come up with a series of switches on the shifter and seat maybe hooked up to a relay to cut the ignition. I agree that i normally dont like them like on my garden tractor but something about this just scared the crap out of me. I'm not sure if i could even see the front edge of the bucket standing up, haven't had to do it.

BTW wolfman, I've gotten good info from you helping another member out with the same tractor as mine. It's a good old piece and have been very happy with my purchase.

That series has some very good features, one being the steering, Full hydrostat is the only way to go, makes steering a dream.

I bought mine in sad shape but cheap, rebuild about 80% of it, but now its a real dependable and nice to operate unit.

I have friends that want to buy it from me all the time.

I'll send you a link for a download of the WSM if you don't have it already.

To do a dead man's switch on that model you will either need a seat with the switch build into it (best option) or buy seat tracks with a spring loaded seat lift or make your own with a switch built onto it.

You would just loop into the signal power that feeds the fuel stop solenoid relay timer, so if you break the feed it trips the timer and stops the engine.

If you need more clarity I can give it to you in wire colors and location of the cut, just PM me.

You could opt for what the boaters have on the outboard motor control.
You have a tether which you clip to yourself and the other end is over a simple toggle switch.
Pull on the tether, such as when falling out of the boat, and the toggle switch goes off. Cheap and effective....as long as you hock yourself to the toggle.
Seadoo's and other PWC's have similar tethers but they are tied into the electronics and not practical to retrofit,

Yes, that is what I referred to above.

Simple and if you do not want to use it you can leave it off.
You can stand up and not kill the engine.
Or make a big rip cord to grab as you fly off
