Section 3 - Operation
Hydraulic Operation -
Remote Control Valve Operation -
Tractors are equipped with either a Standard Flow System or High Flow System..
Standard Flow System - 4 to 6 control valves
The standard flow system consists of dual variable displacement piston pumps located in tandem on the left side of the engine (1).. The Pumps have a combined rating of 208 L/min (55 GPM).. Pump 1 provides priority hydraulic supply to the steering and braking system followed by remote control valves 1 and 2.. Pump 2 supplies remote control valves 3 to 6..
The remote control valve assembly is divided internally into two separate systems.. One side of the system can be used for the operation of a high flow/low pressure requirement and the other side of the system can be used for a low flow/high pressure requirement such as found on certain hydraulic driven air seeders..

High Flow System (Optional) - 6 or 8 control valves
Tractors equipped with the High Flow Plus system have a supplementary third, piston/gear pump mounted on the rear of the transmission case (2).. The pump is rated at 95 L/min (25 GPM) providing a total system rating of 303 L/min (80 GPM)..
The high flow system offers increased flow and triple system capability which will allow for more efficient operation of large individual hydraulic loads such as dual orbit motors and remote cylinders..
WARNING: Hydraulic oil escaping under pressure can penetrate the skin causing serious injury.
•Use a piece of cardboard or paper, instead of your hand, to search for leaks.
•Stop the engine and relieve pressure before connecting or disconnecting lines.
•Tighten all connections before starting the engine or pressurizing lines.
If any fluid is injected into the skin, obtain medical attention immediately or gangrene may result.
