bluetooth deadman ignition switch

[relaqbr]

Okay why is this harder than it looks. I want it to be optional. So that I can turn on the system only when I'm doing specific things on the tractor. I definitely do not want it tied to the seat in anyway. I have googled and googled and googled and can not find anything that seems reasonable. I was thinking I could do it with a long wire but bluetooth would be so much better and not have a wire trailing me around. Has anyone done something, seen something, built something?

I don't understand. What would this be used for? In case the tractor threw you off and kept going?

Not a Bluetooth solution, but how about a simple on/off switch next to the seat? Just tie it to the existing wiring.

blue tooth? so you can fall off and the tractor continue going ? 25-50' befor ethe signal is lost?

or when you drive under a power line and the signal drops and you stall?

RFID might be a lil more forgiving as an op presence switch.. and a magnetic switch with a tethered dongle even better..

Do you want a deadman switch (hold down to keep the tractor on), or just remote shutoff switch? If just a remote shutoff switch, take a look at something like: 4 Channel RF Wireless Remote Control 433MHz Latch New | eBay I have 2 of them in our cars to lock/unlock both cars with 1 remote. It could also act as a deadman, but it would be a pain to use.

Thank you for all the replies. But no, really, like I said, I don't want it tied to this seat. And no I have not fallen out of the seat lately knock on wood. I guess none of us are ever off the seat working on external equipment. To be specific I have a concrete mixer off the front quick attach. It is rotating and there are places to get hung up on. I thought it would be smart from a safety perspective to have a dead man's switch when I'm off the seat working with the concrete mixer. I also have put a small hydraulic motor on a shredder and run it at various times with the tractor hydraulics. Both of these pieces of equipment would be better safety wise with a deadman switch to the tractor. And if the switch is too hard to activate -- It would be it would be too hard to activate as I am being mangled.

Thanks for all the replies!

So you want something that you have to keep pressed in order for the tractor to continue running? That's going to be tricky. With wireless, a quick loss of signal, and the tractor cuts off in the middle of you doing something. With wired, it'd be a *lot* easier to do, but you're on a leash and can't easily walk around.

If this almost always involves standing by the 3PH, I'd suggest looking at... find a wire that keeps the tractor running. either the ignition switch or a safety. Find a jack that remains closed when nothing is plugged into it. Mount the jack on the rear of the tractor and splice it into the wire you found earlier, so that it is in series with whatever else is there (ignition switch, safety, etc). Make you a harness with a connector that fits into that jack and has a momentary, normally open, switch on the end of a 5/10/etc foot wire harness with a nice comfortable handle. You release the switch, the circuit opens, the tractor dies. Need to go grab that branch out of your reach, unplug the jack and everything works like normal until you get back and plug it back in. I think something similar to this may be available for boating, but it would be for you being a certain distance away (i.e., overboard).

This is somewhere that you probably want to stick with the KISS principle. Bluetooth is just a way to communicate. You'd need to build smarts on each end so that something exists to communicate over the bluetooth.

You may also consider adding a siren so that it will let someone know you're in trouble.

On the shredder, I would do like the commercial chippers have, a U shaped arch around the hopper that controls the hydraulics for the feed rolls. If you push on it as you get dragged in, it reverses the feed rollers and things back out.
On the mixer, I would have a loop of rope that comes out on standoffs like a "fence" around the mixer (to there you can reach it) and pulls on the lever of a hydraulic valve (like a woodsplitter valve) to shut off the mixer.

Thanks again for the replies. I did notice the boating reference and have googled all sorts of boating switches but still can't find anything like what I am looking 4. okay I said bluetooth but I really do mean just wireless. Bluetooth is a very effective computer chip to computer chip wireless transmission system. And everything these days is computer chip.

I am thinking of adding additional hydraulic systems and I do not want a separate shut off system for each one. -- KISS!!!

have not looked in years but possible some type of RC model control and a servo to operate what ever you want, when my son was at home we bought a lot of stuff throught a company called tower hobbies, Tower Hobbies - Best Source for Radio Control ( R/C or RC ) Cars, Trucks, Airplanes, Boats and Helicopters

they have some 2 channel radios, TowerHobbies.com | Shop by Category: 2-Channel Radios - AM Pistol that way one could run two items via a reciever and servos,
the have transmiters with many more channels as well,


some info on the systems, EasyRC.com

Therein lies the rub... if a safety switch can be enabled or disabled at will, then it will most likely be forgotten when it is most needed. If you have to remember to enable the deadman switch, then you can remember to turn off the tractor before getting off to work around an implement. It doesn't get any easier than that.

one simple idea is a some type of pull out key, that when the key or switch is pulled the tractor shuts down, now with a set of rings/hooks one could set up the switch so you could pull it by a string and by running the string thought a ring or a smooth hooks, one could pull it from any angle on the tractor,

my thought is more like a trailer break away switch but instead of making the circuit break the circuit,

Thanks for all the replies. I have followed all the links and looked at more stuff from the suggestions. Seems as though the link above would work the best. It has an option that could mean that you would have to hold the button down for the function set up. Which of course would work perfectly for a true dead man's switch which is what I want. Just worried a little about the month for shipping. I am just not going to do all the ideas or suggestions that rely on long strings and such. But thanks anyway. other equipment that I am thinking of attaching it to the tractor hydraulics might be an olive press and a grinder. So thanks again for everyone's help.

use a latching system that auto resets at power cycle. an EM switch could be used here. IE.. once you start her up, you have to manually re-enable a DMS.. later when you shut her off, the DMS auto unlatches, and then when you start up again if you want to re-enable, you have to do so. it would be better than a manual on / off switch that can be disabled and left that way untill you remember it.

many shop and industrial power tools have this setup.. that way if power goes out while working, all tools shutt off and non auto restart when power comes back on, as all the EM cutouts reset and unlatch.
