Kubota just cuts off

[inseeme]

Mowing my grass today my F3680 out front mower, just died about 8 times over 2 hours still about a month left on warranty, just a pain to haul somewhere, everytime it would die, crank back up run 15 minutes or so and die again. Any suggestions, has 114 hour on machine.

I would check the fuel filters first and then the safety cutoff switches (like on the seat etc.) My guess is it is either fuel delivery or a safety cutoff that is causing the problem.

the sound of the engine should clue you into the cause of the cutoff.

a safety switch will cause instant cutoff..just like cutting off the key.

bad fuel delivery will be a sputter and die situation.

Watch carefully... it is easy to not be aware of lifting yourself out of the seat sufficiently to allow the seat deadman switch to trip...happens to me often when i lean forward to see bucket above cab roof.

if it will sit and idle for a long time without you in the seat, then I vote for a safety cutoff....
