CAUTION: Escaping fluid under pressure can penetrate the skin causing serious personal injury. Avoid the hazard by relieving pressure before disconnecting the system lines.

If an accident occurs, consult a doctor immediately. Any fluid that penetrates the skin must be surgically removed within a few hours or gangrene can result.

CAUTION: Help prevent personal injury. Before implements are attached, hydraulic hoses are connected, and to avoid unintentional implement movement, observe the following:

• Shut off the engine.

• Set selective control valve controls to neutral position and lock them.

IMPORTANT: Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses regularly.

Any dirt, dust, or other foreign material can damage hydraulic system. Thoroughly clean hydraulic hoses and SCVs before connecting an implement to the tractor.

IMPORTANT: Steam cleaning or using a high pressure washer in the area around the SCV connections and electronics may damage equipment. In the case of high-pressure washers with a pressure of more than 6900 kPa (69 bar) (1000 psi), a min. distance of 200 mm (8 in) to the connections has to be maintained.

  1. Engage the park lock and shut off the engine.

  2. Lock out SCV controls:

    • Move the multi-function lever to neutral position and latch with the locking button or ring (A).
    • Bring the SCV control lever into the neutral position and lock with the locking button or lever (B).

  3. Clean dust caps. Turn dust covers up to expose connections.

  4. IMPORTANT: Be sure to correctly connect hydraulic hoses to couplers. If hose fittings are reversed, machine will not respond to system controls as expected.

    Assignment of SCVs at rear

    Extend = Left Port

    Retract = Right Port

    NOTE: The SCV connections are identified by numbers I to VI (C).

    Check if symbols on connection identification plates (D) or (E), indicating cylinder movement, match cylinder travel direction.

  5. If a single-acting cylinder is connected to an SCV, plug hose into extension side (F). When connecting double-acting cylinders, extension side is left side and retraction side is right side (G).

  6. Push hose(s) firmly into connection(s).

NOTE: SCVs are color-coded for easier identification. Hose identification kits are available from your John Deere™ dealer.
