Hydraulic Cylinder Functions
Use the following table to check the tractor valve function against the cylinder behavior. The hydraulic flow to the Transport
and Work Circuits should not exceed 6 gpm. The system pressure will need to be 2000 psi minimum.

1. Operate only on a pressure compensated, load sensing, or flow compensated closed center pump
system. Use of an open center tractor hydraulic system will result in the hydraulic flow
continuously bypassing through the relief valve resulting in an increase engine horsepower
requirement to turn the pump at the relief valve pressure. This will overheat the oil and the tractor
very quickly.
2. It is important to note that some older tractors will have a detented valve that will kick out when
system pressure is achieved. This valve must be over-ridden. The valve must remain in detented
position during field operations. Maintaining pressure will allow the system to keep the toolbar at a
constant depth.
