b3200 how to bypass all the safety switches to get started when in woods

arkydog · Mar 6, 2016

i know that you are not suppose to bypass the safety switches on a tractor and i am glad they are all there. a couple of days age i was about two miles from the house at the end of county road at a neighbors shed (which i was supposed to be. since i have had a stroke, i always shut the tractor down to get off and on the tractor so i won't bump any levers and cause any injury to myself, kind of a safety thing. any way, when i shut the b3200 down to get off to do something and got back on, it wouldn't start. i can't walk more than a couple of hundred yards, i tried every lever, switch i could think of. after about an hour of trying every lever and switch i could think of, i finally found the one that let it start. I'm also diabetic on insulin and had forgotten glucose tablets to keep from having a reaction.

one time at the house tractor wouldn't start after trying everything i couldn't start it. whent back to house and got on this form and finally found where someone had same problem. it was the hydrostatic go pedal safety switch which need to be lubed so it can easily slide forward and back. no slide and got stuck slightly forward and wouldn't start. no amount of moving safety switches would have gotten it started.

what I'm asking, is there some kind of jumper wire or something that will bypass everything and let me get it started and running in case it won't start away from home and no cell service so i can get it home to fix out why it won't start?
i used to cuss safety devices but now i think they are the for a good reason. i would like to be able to get home so i can fix problem.

i would appreciate any help. you can private message me if you don't want to post where everyone can see. i understand. i haven't got much help from dealer where i bought tractor from. i guess kind of a liability thing.

thanks ahead of time to every reading this an to those to help. i have been along time member also. thanks rob

If it was me I would go to the auto parts and buy a remote starter switch, then keep it in the tool box. Then you can iump the solenoid to start it, must have the key on. If you don't know how,its the small wire feeding the solenoid and bigger wire from battery.

PS Be in the seat when you do this, the leads should be long enough.

The remote starter switch is a great idea to crank the engine.
What if a safety switch is trying to activate the fuel shutoff?
Perhaps pull the connector off the shutdown solenoid to let the engine start?

thanks. first time it wouldn't start, when hydrostatic pedal safety wouldn't return to center, t tried to jump the start starter which got engine to crank but i guess injection pump wouldn't deliver and couldn't figure out how to jump around. three wires going to it. that when TBN guys told the hydro switch sticks. i wonder if a wire diagram would help to figure a simple 1 or 2 jumper wire get me home emergency fix??

it happened again. started tractor this morning and drove about .5 miles to the dumpster to pack it down with backhoe. luckily i forgot the key to dumpster and had to go back home to get it. when i got back home and shut off tractor to get key, getting back on it wouldn't start again.

luckily i was at home and not away from house. spent several hours trying to figure out what was causing no start. went inside, came back out and it started. i tried jumped starter solenoid and it would crank but i guess no fuel.

how can i bypass the fuel shut off? it has 2 wires going to it. one larger white wire about 12 ga and one white/blue tracer about 16-18 gauge.

if anyone can tell me how to by-pass the fuel shutoff on the injection pump, then i can carry like a jumper wire andscrewdriverto get running in an emergency, that would be assume!!

You can defeat each switch by itself. The one giving you the issue is probably the hyrdo pedal. I have the same issue on my tractor and ended up just bypassing it. You can unplug it and then just out a wire across the lead to jumper it. I just make sure to have the brake on when I start now. I think its the switches themselves or maybe an adjustment, but even well lubed and visually marking my hydro pedal at center mine still gave me issues.

You shouldn't have to jump fuel shut off if key is on, now if key switch or a timer relay is bad then you would have to. Still work on getting the safety switchs working right.

i understand to get the safety switches correct. after having a stroke and having tractor off my property helping others that helped me and my wife when in hospital and nursing home, we live at the end of an 8 mile road. one way in, one way out.

i AWALAYS shut off tractor getting off and on. three times now because of safety switches, one switch mallfunction, i was stranded for hours and being insulin diabetic doesn't help matters. and i can't walk more than a 100 yards or so.

what in down to with others help, is how to bypass fuel shut off in an emergency situation. thanks rob

Correct me if I'm wrong, but I believe the fuel shutoff solenoid turns the fuel on when activated, otherwise it would require power all the time that it wasn't running, draining the battery. Before they started using solenoids, Bobcat 743s had a choke cable that you pulled to kill the engine. It could be tied off to something with a piece of wire to hold it open. That would probably be a good alternate plan in the event that the solenoid got weak and wouldn't hold, at least you could keep it running. A functioning solenoid should have a pull and a hold coil; for an emergency bypass you only need to supply power to the hold coil, it can be racked into position by hand. Then a remote starter button hooked to the starter should get it running, regardless of what safety-**** garbage is upstream. Whether it will move, is another matter, depending on what types of interlocks are involved.

thanks flyerdan. the safety switches i think is to keep the starter solenoid from energizing when key is put in start position and the fuel shutoff solenoid is activated to let fuel flow to pump. safety switches complete the circuit and let it run and start.

the last time i checked the plug to the fuel cutoff switch had power on the wire harness side at both sides, small wire and big wire. that was with the key on but i don't remember if that was before or after the no start situation. i will try to check tomorrow since we have 6 inches of rain predicted and we have already had a 1.25 inches.

i hate to power one side or the other cause i would hate to burn it up. i'm assuming in an emergency situation that to get the tractor to home all you would need to do is get the fuel shutoff so its flowing and to crank the engine over since its a diesel. thanks again rob
