Linkage is most likely stuck on draft control from sitting. Remove all the small linkage from under tractor going to rear lift and free it all up. Likely has the draft stuck in raise position.

It is the traction booster linkage that is rusted in the activated position.  Since the tractor has been sitting in the woods for 18 years, I would take the mechanical linkage apart and clean and lubricate all of the pivot points.  The valve body itself should be fine.

Cylinders are rusted on inside. Take a hyd. hose off one cylinder and see if it will go down.  If it was linkage, it would have went up as soon as it started.
  Put alot of weight on it. May have to take cylinders apart and hone.  MACK
