I have a JD 2030 with 3100 hours on it and am having some problems the the three point. Recently while pushing snow with a 8' blade the tree point would jump up into the highest position and stay locked there with no response when I moved the control level up and down. After moving the hydraulic remote lever back and forth with the three point control arm in the highest position and then lowering the lever i could get it to come down again untill it happened again. It will also work if you turn the tractor off for a couple of seconds and then restart. Sometimes there does seem to be a hissing sound coming from the rockshaft housing and the pump does make allot of clatter when this happens. Power steering and brakes are fine. Any thoughts could this be orings in the rockshaft cylinder? Thanks for any help.

Sounds like its compensating for a leak. Does the rockshaft settle fairly quickly with a load when the tractor is shut down? Pull the hydraulic filler cap off with the tractor at an idle and look inside with a flashlight. Look for oil spraying around. Anuther thing to do to help the diagnosis is changing the setting on the draft control lever and see if that makes any differences.

Checked inside with a flashlight looks like oil leaking near right front. Tried adjusting draft control with no help. I did pull out the flow control valve located on the right side of the rockshaft housing. When looking at the valve it had a very light scratch on it. Could this be a problem? Also sometimes the rockshaft settles with the tractor off and sometimes it doesn't when it does settle it only takes 15 to 20 minutes to do so.Thanks
