My neighbor has a YM1500 he's been working on. I took a look at it with him just now and figured I should get some opinions/ advice. The 3 pt hitch lift arms are lifted all the way up and seem stuck. I see two possibilities, although there may be others.
#1)The little control valve arrangement looks to be working correctly, with the possibility that it is not releasing pressure?
There is a control valve under the seat that, when you pull up on the height adjustment, is pushed in to raise the arms. We can push on that and hear the hydraulics working, but since the arms are all the way up already, no movement.
This control valve may not be coming all the way back out to allow the pressure off the lift arms.
There's a little doo-dad on the side of this valve, not sure what it does. Didn't want to tear up my neighbor's tractor without getting some advice.
#2) Maybe the arms are just stuck or cammed over or jammed or otherwise in some sort of mechanical bind?
Anyone with ideas or a good place to find mechanical drawings or download the owner's manual, give me a shout. This old guy must be 80 and is still tinkering on tractors; I'd like to be able to help him figure this one out...
