Hello, working on a family members d17 series 1 and looking for some knowledge. Any time the engine is running the lift arms raise like there's pressure going to them regardless of where the controll lever is set at. The linkage for the traction booster is unhooked and I made sure the rod at the bottom of the tractor is not hanging up and causing troubles. If I shut the tractor off the lift arms will drop but will not while tractor is running. The hydraulic lever will make them raise faster when moved but when it's at the lower setting they still creep up. Wondering if I have a valve leaking by or something else? Any help would be greatly appreciated, thanks!

The Traction Booster rod under the belly MUST BE HOOKED UP and adjust the nuts FORWARD as far as they can go for now. Traction Booster lever must be down/horizontal.

I forgot to mention traction booster has been unhooked as long as he's owned the tractor but the lift arm problem started recently and has progressively gotten worse.

Don't argue. Hook it back up and adjust the nuts FORWARD and then report back if it doesn't work. T.B. lever must be DOWN/HORIZONTAL.
