Using Third Selective Control Valve (SCV) Outlet—If Equipped

CAUTION: Avoid injury! Escaping fluid under high pressure can penetrate the skin and cause serious injury. Avoid the hazard by relieving pressure before connecting hydraulic or other lines. Tighten all connections before applying pressure.

• Search for leaks with a piece of cardboard. Protect hands and body from high-pressure fluids.

• If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A. In the United States and Canada only, this information may be obtained by calling 1-800-822-8262.

NOTE: Some continuous flow attachments can elevate tractor oil temperature. Make sure to refer to the operator’s manual of the attachment and supply the device the proper flow rate. In the event that the tractor hydraulic system overheats, the valve disengages, and the light remains lit. Operate the tractor for 10 minutes at mid engine speed to cool it down, identify the cause of the overheating, and resume work.

This machine model series can be equipped with an optional third selective control valve (SCV) outlet kit to operate hydraulically driven implements from one set of outlets at the mid-mount position or the rear-mount position.

The machine-mounted hydraulic outlets are female quick couplers.

Third SCV Continuous Flow Switch (Cab Shown; OOS Similar)

A - Continuous Flow Switch

B - Off

C - Enable/Activate

NOTE: Continuous flow will not be available to the rear outlets on machines equipped with the third selective control valve and the diverter option.

• Continuous Flow Switch (A): This switch supplies continuous flow to a hydraulic device.

• Off (B): Place switch in this position to deactivate continuous flow from the third SCV outlet or depress the bottom of the control switch.

NOTE: If the continuous flow is activated, the green light in the switch illuminates.

• Enable/Activate (C): This is a momentary position that activates the third SCV continuous flow circuit. When the switch is depressed and released, it returns to the center on position. Turning the key switch off deactivates the continuous flow circuit. When the key switch is turned on, the third SCV continuous flow circuit will not activate until after the operator presses and releases the switch in the momentary enable (C) position.


Using Third Selective Control Valve (SCV) Outlet Control

The third (SCV) outlet may be operated in a momentary condition to operate attachments such as extending or retracting a hydraulic cylinder. The attachment receives full hydraulic flow in direct response to the use of the control switch.

    H - Bottom of SCV Control Switch

    Depress the top of the third (SCV) control switch (E) to allow flow from the circuit out the upper outlet (F) and return to the machine through the lower outlet (G).



  2. Depress the bottom of the third (SCV) control switch (H) to allow flow from the circuit out the lower outlet (G) and return to the machine through the upper outlet (F).

IMPORTANT: Avoid damage! To prevent contamination of female quick couplers, install color-coded hose ends in the couplers when not being used.
