after starting tractor, hydraulics kick in and will not relieve , three point goes up, but not down, tractor running under load sitting still, like a relief valve stuck, any ideas ??

Hi, first thing make sure the draft control lever is fully forward. Second is dirt in the unloading valve under the seat.
Third would be a problem with control lever mechanism inside the hydraulic housing.

Possibly draft control sensor ib the rear housing is no longer under the curved "Cam" (remove the top link plate from the back to get into the location) Jim

Sounds like you might have caught the SCV lever. Easy to do it is right beside your right foot. We have done it many times. Does the same thing.

Yep, same here with our 674's. Does that exact thing. Especially easy to catch with the extended lever I built for them.
