5. The unused port on the tee 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. Detailed
instructions will be provided later on page 28 under the
heading “Hydraulic Flow Control”.

Solenoid Control
Hydraulic oil is supplied to the solenoid valve block
through two hydraulic lines connected to one of the
tractor’s remote duplex outlets. “ARM 1”, “ARM 2”, and
“Deck Pivot” hydraulic cylinders are plumbed to the
solenoid valve block 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 flow. An auxiliary
flow control valve on the cutter frame diverts excess oil
back to the tractor. This valve regulates volume flow of
hydraulic oil to the hydraulic cylinders and helps cool the
hydraulic oil by keeping back pressure down.
Tractors Rated 15 GPM and Under
Refer to Figure 2-3:
1. Pressure line #1 is plumbed from the lower port in the
solenoid valve block 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” and the opposite
end is fitted with a Pioneer-quick disconnect coupler.
3. Return line #1 is plumbed from the upper port in the
solenoid valve block to the tee at the flow control
valve with a check valve between the tee and hose.
4. Return line #2 is plumbed to the tee at the flow
control valve and the opposite end is fitted with a
Pioneer-quick disconnect coupler.
5. Connect return line #2 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.
Tractors Rated 16 GPM and Above
Refer to Figure 2-4:
1. Return line #1 is plumbed to the upper port in the
solenoid valve block and the opposite end is fitted
with a Pioneer-quick disconnect coupler.
2. Pressure line #1 is plumbed from the lower port in the
solenoid valve block 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” and the opposite
end is fitted with a Pioneer-quick disconnect coupler.
4. Return line #2 is plumbed to the tee at the flow
control valve and the opposite end is plumbed 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/or in the cylinders may occur if oil
becomes overheated. Make sure pressure & return
hoses are configured to match tractor rated GPMs.
See your tractor’s manual to determine its rated flow.
