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.

Solenoid Controlled Cylinders

Refer to Figure 1-9:

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.

Hydraulic & Solenoid Hook-UP (16 GPM Flow & Above)

Figure 1-9

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.

IMPORTANT: Plumbing instructions in step step 1

below are for cutters hooked to tractors capable of

16 GPM hydraulic flow and above.

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.

IMPORTANT: Plumbing instructions in steps step 2

to step 5 below are for all cutters with solenoid

controlled cylinders.
