Kubota u173a. 2012
All works ok apart from arm and tracks which I assumed was a faulty safety switch, I have checked this and all is ok, If I give it full revs I get minimal track movement and arm movement, I have removed the hydraulic pump and spline etc all intact so could it be the solenoid off the safety switch? If so where would that be located? I would very much appreciate any advice
Regards

At 600 hrs the hydro peddle went nuts. The tractor would run/move until I dropped the scraper and the peddle hammered like a machine gun.
The dealer checked out, with no solution and called Kubota Central Service Center. A rep went to the dealer and made them repeat all the tests (mostly hyd pressures)they had performed. The service rep told them to give me full value on whatever I wanted. He took the machine back to headquarters. Quite a time elapsed before we got an answer. Wait for it on the next line.
THE WEAR PLATE BETWEEN THE PISTONS IN THE HYD PUMP WAS MISSING. THAT MEANT THE PISTONS WERE BEING PULLED .461 TOO FAR IN THEIR BORES. Probably built on Friday or Monday by a subsittute assembler.
