Hello, recentlyy brother was cutting hay with our 1070 and he said he pushed in the clutch, and when he let the clutch out the tractor didnt move. he pushedand released the cluth again and tractor took off. he said it did it again a while later. i checked it over and noticed that when the tractor is at an idle and pushing in the clutch pedal. the tractor does not surge like normal. you rev the tractor up 400-500 RPMS and the tractor will surge when pedal is pushed and released, i drove the tractorback to my shop and when turning and dead heading the power steering pump, the tractor stopped. i hooked a gauge to the lube porton top of trans. at idle i got 0 psi, rev up and get 45psi or so in P/S 1 and 3 for about 35 psi in P/S 2. i put a gauge in the hydraulic coupler and checked pressure, at idle i got 2200 psi. when at idle and revving engine up slow, can hear a click from trans control housing area and then clutch pedal will surge engine with clutch pedal is pushed down. wondering on some ideas to check! Thanks for you time! Greg
 
My 870 would do that when turning and using the brake at the same time. I was told it was the brake/steering part of the hydraulic pump getting weak. I ran it that way another 2 years before the hydraulic pump died. Replaced the pump and it has not done it since.
 
thanks for replying. did you have clutch pedal repsponse at an idle? i know for the last couple years it seemed the hydraulics were slow, you rev up the tractor and they function fine.
 
The P Shift needs the return oil from the steering and brake section of the hyd pump. When that flow gets weak the tractor will stop moving if it is a P Shift unit like yours. As D Kase has mentioned sounds like you need to replace the hyd pump. Rod.
