Using Rear Outlet Selective Control Valve (SCV)

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.

This machine model series can be equipped with an optional hydraulic third selective control valve (SCV) and hydraulic outlets to operate hydraulically driven implements.

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

1. Turn the rear outlet activation switch (A) to the on (C) position.

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

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

4. Turn T handle (I) counterclockwise to open vent valve and remove pressure on both rear outlets before connecting or disconnecting accessories.

   • Turn T handle (I) clockwise to close vent valve once pressure on both rear outlets has been relieved.

     See your implement operators manual for implement functions that correspond to quick couplers used.

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