B7510 shutting down while running.

[PSDStu]

I have had a problem develop over the last couple of weeks where my tractor will be running along fine and then it just wants to shutdown. I have been doing alot of mowing and bushogging and when this shutdown started to happen I would just push in the HST clutch pedal and this would keep the engine from shutting down. I figured that maybe the seat switch was acting up.

Then yesterday I had the boxblade on the tractor and it once again tried to shutdown while I was using the tractor. I pushed in the clutch pedal and the engine kept running so I ruled out the PTO/Seat switch.

It's not that the engine is stalling from being in an overloaded condition.... it just seems like some sort of safety switch is out of adjustment.

Is there someother safety switch I should be looking at to cause this shutdown problem?

in this situation a seat switch is the olny switch which could cause it to shut down. try that for a start. are you sure its not a fuel block etc. when it shuts down and you catch it with the pedal do you hear a click before the engine comes back to life. if so its a safety switch as the noise is the engine stop solenoid releasing. if you took the bonnet off could you see the solinoid move. if so try and watch what it does. again if its moving its a seat switch.
