Probably been ask about before but when warmedup running haybine push in clutch and hydraulic pump stops till I let clutch out and
it starts working again,oil, filter and screen are fine. Go ahead and give me the BAD news first. THANKS
 
How long are you holding the clutch pedal down? That's normal, as holding the clutch pedal down stops the charging pump that supplies the front radial pump.
 
It should not loose hydraulic pressure as soon as you push the clutch down. Should have at least 5 seconds of hidraulic pressure if not longer. Sounds like you have an internal leak bleeding off the residual oil left in the circuit. Could be a remote leaking internally, or rockshaft valve leaking
 
Your have a stand by oil leak,,and on console tractors it is likely to be the PTO operating valve under the dash,,remove the left side panel and locate the valve,,remove the small oil line feeding it,cap both ends,,then see if your system improves,,and if it dont start seeing if a SCV or steering valve is heating up too quick,,this is how i start the search..
 
Deere offered a complete valve at one time,,,but not any more....Isolating the pressure to it will help determine if it is bad.
 
I just found that the 3pt only works on D setting on draft control,is this a symptom of an internal leak? Tim S can you e-mail?
