5. The unused port on the tee at the flow control valve
must be plugged.
6. Connect return line #1 and pressure line #2 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.
Flow Control Valve Adjustments
Flow control valve adjustments are made after the
electrical controls have been installed. Refer to
“Hydraulic Flow Control” on page 32.

Solenoid Control
Hydraulic oil is supplied to the solenoid valve from the
tractor’s remote duplex outlets. Hydraulic cylinders for
“ARM 1”, “ARM 2”, and “Deck Pivot” are plumbed to the
solenoid valve and controlled from the tractor seat with
an electrically operated control stick. The speed at which
the cylinders extend and retract is controlled with a flow
control valve mounted on the cutter frame.
Flow Control Valve Plumbing
The tractor duplex outlet connected to the solenoid valve
block must be capable of continuous hydraulic flow. An
auxiliary flow control valve on the cutter diverts excess oil
flow back to the tractor to keep the oil cooler.
Tractors With 15 gpm & Below Hydraulic Flow
(56.8 liters per minute and below)
Refer to Figure 2-3:
1. Pressure line #1 is plumbed to the lower port in the
solenoid valve block and to the port labeled “CF” in
the flow control valve.
2. Pressure line #2 is plumbed to the bottom port in the
flow control valve port labeled “IN” with a Pioneer-
quick disconnect coupler on the opposite end.
3. Return line #1 is plumbed to the upper port in the
solenoid valve block and to the check valve in the tee
at the flow control valve.
4. Return line #2 is plumbed to the tee at the flow
control valve with a Pioneer-quick disconnect coupler
on the opposite end.
5. Connect return line #2 and pressure line #2 to one of
the tractor’s duplex outlets. Some tractors use quick
couplers other than Pioneer couplers.
Tractors With 16 gpm & Above Hydraulic Flow
(60.6 liters per minute and above)
Refer to Figure 2-4:
1. Return line #1 is plumbed to the upper port in the
solenoid valve block with a Pioneer-quick disconnect
coupler on the opposite end.
2. Pressure line #1 is plumbed to the lower port in the
solenoid valve block and to the port labeled “CF” in
the flow control valve.
3. Pressure line #2 is plumbed to the port in the bottom
of the flow control valve labeled “IN” with a Pioneer-
quick disconnect coupler on the opposite end.
4. Return line #2 is plumbed to the tee in the flow control
valve and to either the tractor sump or deck motor
return line. Fittings to plumb to tractor sump or motor
return line are customer supplied.
IMPORTANT: Damage to o-rings in the solenoid
valve and hydraulic cylinders can occur if the oil is
overheated. Refer to your tractor’s manual to make
sure oil pressure and return hoses are configured to
match your tractor’s rated hydraulic flow.
