Chapter 7 Tractor's PTO System Section 3 Hydraulic Lift Hitch 2.3 Position Adjustment Farm tools maintenance a certain working position relying on the oil pressure in hydraulic cylinders. The farm tools'locations relative to the tractor are fixed when working. The tilth is uniform when the ground is flat,but the traction and engine load fluctuate largely when soil behavior changes large. The tilth is not uniform when the ground is uneven.
