Add one more switch failure, 2013 B3350. Has anyone disassembled switch to fix or see what's going on?

I’m wondering if it might be worth having a spare switch, that is if they keep failing.

Judgement call. Here's the quick fix I used to get it running until the new switch arrives (we should get more snow this weekend and I'm spoiled by the front blower).

This is on a B3350 which no doubt is the same switch as the 2650.
I removed the switch from the bracket, letting it hang down, removed one of the mounting nuts. Determined that 1/2" male pipe thread will "start" into the removed nut. Used a PVC 1/2" threaded end cap that depressed the switch plunger and then threaded onto the switch male threads to stay firmly in place - good fix and easy too! Then I used some hook and loop tape to fasten the switch to a fabric sleeved nearby pipe. I needed to keep the metal parts of the switch insulated from tractor ground, as there is apparently an intermittent short in the switch that was grounding to tractor frame and blowing the 5 amp "Panel ECU" fuse. Tested fine.

I plan on taking apart the switch to find out why the internal contacts intermittently short to switch body/ground. And will report back.

Having the same issue in my B2650. Glad to find this solution.

Yes, common fault on the switch. I just left my "fix" in place, even though I have a new switch on the shelf. The switch is typical overkill and it's only job is to keep you from pushing on the go pedal while starting the tractor - oh, and of bringing everything to a halt, usually at the most inopportune time.

B2630 died in the field; OPC fuse blown. Replaced fuse and started right up. But it only lasted a couple minutes and fuse blew and tractor died. So followed everyone's advice to find the HST switch. It was hiding behind large wire harness. Pulled switch out and jumpered the female spade connectors. Back in operation again without idiot switch.

Ya know, if Kubota truly cared about its customers, they'd send out a letter to owners and recall this switch. Instead they leave it to wreck havoc on owner's schedules, time and money. But then they've alreade raked me over the orange coals having to fork over more than $3,500 for a new DPF filter at less than 800 hours.

Did you know kubota has extended the emissions warranty to 10 years? 2014 B3350 700 hrs, only one abnormal parked regen, but i have had 3 regens in approx 15 hrs, so i think problems ahead. love the tractor
