Tractor Shuts Off While Mowing

[GPintheMitten]

I have a B2620 Hst with about 400 hours. Something is causing it to shuttoff while I am mowing. At first it was ocassional so I ignored it.

Tonight it must have done it 30 times. Obviously I cant ignore it. I just wanted to get the darn grass cut before it gets any colder.

So it is probably one of the safeties. Where should I look first? I raised the seat and looked at the seat safety but I didnt notice an obvious problem.

Jump the seat switch and see what happens.

Seat switches can be the problem and the first thing to check.

Ditto , mine has a permanent test jumper.

I hate not to be able to raise up out of the seat and look over the hood and loader, esp. with the forks on.

Interlock on the pto shift lever.

Thanks guys. I'll start with the seat switch.

So, it just shuts of while mowing. Then, what happens when you restart? Do you have to move or jingle anything to get it to restart? Reposition yourself on the seat? Or, D\does it just restart as normal? If you have to do something to make it restart could be a place to look first.

All I have to do is take it out of pto and restart it and put it back into pto. Sometimes when it starts to idle down like it is going to shut off, I take my foot off the hst pedal and it recovers. Sometimes I push the clutch in and it recovers. I'm going to go out later today and bypass the seat switch and see if that solves it. It's pretty frustrating the way it is, and it has gotten gradually more frequent. I think it may do it without the pto on as well but not sure. I think it did it a few weeks ago with just operating the loader on a project, but can't say for sure.

Keep at it, we will figure it out.
