BX2350 D dies

[Willie G.]

I appreciate all of the help you'all gave me when I had a hydraulic leak. I got that fixed with The Lord's guidance, and wisdom from you,'all. My new-old problem occurred before I had the hydraulic leak. When I engage the pedals (forward or backward) on the HSD the tractor dies. It developed this one day while I was using it and didn't think I'd get it back to the barn. I unplugged the stop solenoid, and I didn't have the problem, just had to manually shut the fuel off. I plugged the stop solenoid in started the tractor, it idled fine. Turned the key off and the solenoid engaged and cut the fuel off and about 5 or so seconds the stop solenoid disengaged, so I don't think it's a relay timer. When I had the tractor apart fixing the hydraulic leak(s) I took all of the safety switches off, including the seat switches, and tested them with an ohm meter and they all read good. I have been using the tractor with the stop solenoid unplugged is there some gremlin hiding somewhere that I didn't think to look for that might be causing the problem? Or an adjustment I can make? Any help would be appreciated. My wife would appreciate being able to turn the key of and it stop, instead of shutting it off manually, or me installing a kill button inline with the stop solenoid?

It sure sounds like a safety switch issue. Since there is a operators presence switch that is suppose to sense someone in the seat, that’s my guess.

 

[Willie G.]

The presence switch is mounted behind the seat, the spring mashes a piece of metal down to activate the switch. It is working correctly. There is also a presence switch on the front left of the seat that activates when the seat is down an someone sets in it. When the seat is folded forward the switch is deactivated and the tractor won't run. What has me confused is that it only does it when I'm sitting in the seat or when I'm out of the seat (with the rear presence switch activated by hand when I'm out of the seat) and press the HSD pedals. All the switches have been tested with an ohm meter. That's why I wonder if there is an adjustment on any switch that could be made to stop this from happening. Any help would be appreciated.

The second switch for the seat allows the rear pto to run with the seat flipped up, like when running a rear pto generator.

I still think it has something to do with the seat kill switch. There is a switch on the pedals also that won’t allow the tractor to start if a HST pedal is engaged but it sounds like it starts fine.

The seat switch may be fine and something else in that system may be the problem. I’m betting and you probably already know this the second you engage one of the forward pedals the stop solenoid kicks the tractor off. I wish I could point to something to look for. Maybe try to bypass the seat switch and see what happens? I don’t know what wiring, relays etc are in that circuit.

 

[Willie G.]

Thanks! I've bypassed the presence switch on the back of the seat and the tractor starts fine. It still dies when I press the HST pedals. I've adjusted the HST tension spring to keep the tractor from moving forward when your foot is off of the HST pedals (suppose to do this every 100 hours, as the spring gets weak from stretching, this has probably never been done by the previous owner). The tractor has a timer relay to accuate/deaccuate the stop solenoid and that one works correctly. I checked for shorts in the wiring when I had the tractor apart, an didn't find any. I've looked at the mechanics of the foot pedals and all is well. The only switch it has that's concerns the HST is one in the starting circuit that is linked to the PTO switch and both work properly. All help would be appreciated. Thanks!

My M62 safety switch only cared about pressing the HST pedal if my butt was out of the seat. I think you still have a safety seat issue. Can you bypass them to confirm?

 

[Jchonline]

Just checked the WSM on the L60, I have a safety seat switch and a seat tilt switch. Do you have both?

I believe there is a sensor or switch at the foot pedal, which you didn't mention. For the symptoms you describe, that would be the first thing to check. If it is busted, misaligned, has bad connections, whatever, it would do just what you describe. The other thing is if the wiring to the other safety switches is correct and undamaged.

Yes the HST neutral pedal sensor. It goes to the ECU and senses when the pedal is at neutral, or engaged.

I think the switch for the hast pedal would keep it from starting if it thinks the pedal is pressed. It seems like what the op describes is the tractor is running, he presses the pedal, it dies.

Id have to see some kind of wiring diagram to understand what could be wrong. I assume you checked fuses. I still say it’s the seat safety switch, the pto or HST pedal switches would keep the tractor from starting.

Edit, I say the seat safety switch, but it could be somewhere down stream from the actual switch.

That makes sense. Here is the table for a BX 60series. Not sure if it is the same. If the HST switch were stuck all the time in the OFF position, the tractor would not start.

The presence switch is behind the seat and works. It doesn't have a seat angled switch. The other switch sits to the front bottom left of the seat and is engaged/disengaged when the seat is up or down. The only HST switch I found and tested was under the tractor by the neutral adjustment is used to start the tractor and is normally open until pushed by a piece of metal from the HST to start it. That works correctly. I didn't see a safety switch near the pivot point of the HST Pedals, but will look again. I will try to wire around the other seat switch. Thanks again for the help. One thing I haven't tried is put the tractor in neutral and press on the HST Pedals. I'll have to try that and let y'all know what happens. Hopefully nothing serious, but it's aggravating.

 

[Willie G.]

First I would like to thank everyone for their help. The seat switch was the problem all along with a little help from a gremlin named Billy Goat. I checked the switch and it measured that it was ok, but neglected looking closer at the the other parts around the switch and wiring. Billy Goat had got ahold of the light wiring and chewed and pulled on it, so I fixed that, but at the same time In his search for something to scratch his gums he had pulled things connected to the switch off and apart in the hidden places that are hard to see and caused me to try and find the problem with my bad eyesight. It's fixed now. Thanks for all the help from everyone.

PS: I learned a valuable lesson on looking closer at wiring and things.. And perhaps the most valuable is don't park the tractor overnight in a place a goat can get to it, and look so innocent in the morning. If Emily our Longhorn was still around I would have blamed her, she would eat anything including paper feed sacks, cardboard, oakleaves, prickley pear cactus and pine needles.....and yes! we let her graze, but something's were gourmet to her. God bless!
