Hydraulic Hose Hook-up

!DANGER

Hydraulic fluid under pressure can penetrate skin. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. Use a piece of cardboard or wood rather than hands when searching for hydraulic leaks. If hydraulic fluid is injected into the skin, it must be treated by a doctor within a few hours or gangrene may result.

There are two arrangements to hooking up the hydraulic hoses:

Arrangement - #1 Solenoid Controlled Cylinders: Two duplex outlets are required to operator the arm cylinders, deck pivot cylinder and breakaway cylinder. Parallel arm and deck cylinders are solenoid activated with momentary push button switches at the control stick. Breakaway cylinder is controlled by tractor lever.

Arrangement - #2 Tractor Controlled Cylinders: Four tractor duplex outlets are required to operator the arm cylinders, deck pivot cylinder and breakaway cylinder. Tractor levers operator all four cylinders.

NOTE: The response time with solenoid controlled cylinders is faster than tractor controlled cylinders. Therefore, the operator might want to consider arrangement #1 when frequent changes to deck positioning are required.

Solenoid Controlled Cylinders

Refer to Figure 1-9:

IMPORTANT: Plumbing instructions in step step 1 below are for cutters hooked to tractors capable of 16 GPM hydraulic flow and above.

1.Plumb return line #2 to tractor sump or motor return line (motor return line in Figure 5-5 on page 35). Fittings for plumbing are customer supplied.

IMPORTANT: Plumbing instructions in steps step 2 to step 5 below are for all cutters with solenoid controlled cylinders.

Refer to Figure 1-9:

2.Connect pressure line #1 and return line #1 to one of the tractor’s duplex outlets. Pioneer-quick disconnect hose couplings are supplied with each hose. Some tractors use other types of quick couplers.

3.Determine tractor’s hydraulic configuration. Consult tractor's manual if unsure.

•PC Closed Center System (Pressure Compensating)

•LS Closed Center System (Load Sensing)

•Open Center System

Refer to Figure 1-10:

4.Remove plastic cover located at the rear of the solenoid valve control box.

5.Adjust hydraulic flow control valve Knob at the solenoid valve block as follows:

•PC & LS Closed Center System: (PC = Pressure Compensating) (LS = Load Sensing)

Set solenoid valve on RCP unit to “CLOSED” by turning the flow control knob “CLOCKWISE” until the knob will not rotate any further. Flow control setting to have all oil going to solenoid valve on unit.

•Open Center System:

Set solenoid valve on RCP unit to “OPEN” by turning the flow control knob “COUNTER CLOCKWISE” until knob will not rotate any further. Adjust tractor flow control setting as outlined in “Tractor Flow Control” on page 25.
