What causes the handle on a power trol to pop back after full detent forward or backward? The handle on this 49 A will not move back to neutral position after the attachment has reached full up or down. What part of the power trol unit do I need to check or adjust to remedy this problem?

Yes check oil as said and what kind of oil are you using? Cam latch roller locked or worn, adjusting screw worn or not adjusted correctly, worn cam latch locks, lever binding, or release valve stuck. I&T shop manuals and the JD SM2011 Hydraulics service manual have trouble shooting & rebuild sections. JD publications 800-522-7448.

Now that I re-read your post I got to thinking. Is there enough oil in your Powertrol? Maybe not enough oil is making it not build enough pressure. Just a thought.

Mine had a similar problem. If I didn't have an implement hooked up, the lever would come back from the up position, but not the down. When I do have an implement attached, it will spring back from the down position, but only if it's not idling. My guess is it needs enough pressure to spring back.

Just my .02 from the way mine acted.
