loader problems

[Anonymous Poster]

I'm having problems with my loader raising under no load.
with the bucket full, everything works as it should. When empty, it doesn't want to raise, or drops then raises. sometimes I have to lower it all the way to the ground, and then it will raise after a long delay. Acts like maybe there's air in the hydralics? Why no problems under load, and no problems with the curl with or without load?

What type of tractor do you have and what engine?

I have a JD 655, with hydrostat transmission, and ps. I believe the engine is 16 gross hp.

Sounds like you may have a problem with the selector valve body sticking. when is the last time the oil was changed?
