Darn Seat safety Switch

[Ron D.]

The absolute over-kill on safety switches is due to defense engineering. All because of the unbelievable number of law suits that would be filed if people got hurt and all the "safety" features weren't built into the operational functions of the tractor along with all the "safety" stickers. Nothing ever shut off when you got off of older tractors, and I'm not sure things are any safer today.

I'm not against safety, but it just seems things have gotten way too complicated on something that you should be able to operate and conduct your business without such things shuting you down, costing you money in lost time and repair.

Just my 2 cents.

I have a BX2660. I never had problems with the safety switches until a couple of weeks ago when I first used my rear PTO. It wouldn't start until I made sure the PTO lever was selecting the mid PTO, and of course the PTO power was off.
I've always been able to get off the tractor with the engine running and no parking brake set, as long as HST pedal was in the middle. It could be in slow or fast speed, that never mattered either.
So now I must make sure the PTO is selecting the mid PTO, and sometimes have to engage and disengage the PTO to get it to start.

Thanks for the many suggestions ! Last night I did do a greasing of that hidden zerk under the floor mat.
But that did not help. I also sprayed WD 40 all the linkage under the floor , but will have to look for that plunger ptrotter mentioned (thks) . I took the seat off and took it apart and pulled out the seat switch and verified it was not broken, but connections were a little loose , but after putting back together it still has problem. So I opened the wire connector under the seat and inserted a simple short wire to bypass the switch and of course now it works fine , but a little unsafe I guess. But I don't use a lawnmower attachment and will just be careful to set brake and neutral .
But you are right the complexity of switches is PITA and still means that the signal it was getting is being missinterpretted somewhere , I fixed the symptom not the problem.

Will see about eventually looking at the pto switch , because I did rototill garden last week and that is when it started, so that might be source of malfunction.

I've been having these same issues with my B7800. In researching the problem I have found two things that may be helpful: 1) the seat safety switch, HST (forward-reverse) safety switch and rear PTO safety switch are all connected. If the HST switch is malfunctioning the tractor will stop when you get out of the seat regardless of the PTO safety switch status. 2) the HST safety switch seems to develop burrs and/or start sticking somewhere between the 50 and 150 hour point. Once I actually fix the problem I'll post more.

All my safety switches on my bx24 are now like my old bx22...Common sense is a wonderful thing and a label / switch is not needed.

...Spray a bunch of WD40 or similar product in the switch plunger mechanism and blow it out with air. That may solve the problem. Also make sure the HST pedal is greased properly so that it returns to neutral...

Thanks! this solved my problem and ended much frustration!
