Section 2: Hydraulic Set-up Options
Options
There are three basic Hydraulic Options for the Parallel
Arm Rotary Cutter (Tractor Control, Solenoid Control and
Independent Control). Each of the three basic options
can be purchased with or without gauge wheels. A brief
description of each follows:
Tractor Control
Refer to Figure 2-2:
Four duplex outlets are required to operate “ARM 1”,
“ARM 2”, “Deck Pivot”, and Breakaway cylinders. The
duplex outlets must be capable of infinite variable flow
control (turtle/rabbit control) and should have center
detent “OFF” control levers for controlling the position of
the parallel arm and deck pivot cylinders. If gauge wheels
are included, “ARM 2” and “Deck Pivot” control levers
must be capable of being placed in float position.
The hydraulic motor on the deck is powered by a
hydraulic pump connected to the tractor’s PTO shaft and
is turned “ON” and “OFF” at the tractor’s PTO shaft.
Solenoid Control
Refer to Figure 2-14 on page 26:
With this arrangement, the breakaway cylinder is
coupled directly to a duplex outlet at the tractor and
operated with the tractor’s hydraulic control lever.
The remaining three cylinders (“ARM 1”, “ARM 2” &
“Deck Pivot”) are powered by one duplex outlet at the
tractor with the control lever set for continuos hydraulic
flow. A flow control valve mounted on the cutter frame
regulates oil flow through the solenoid valve block. The
three cylinders are solenoid activated from the tractor
seat with momentary push buttons on the control stick.
If gauge wheels are mounted on the deck, the solenoid
valve block must also include two float valves (poppet
valves) so that “ARM 2” and “Deck Pivot” cylinders can
float with the deck as it is carried by the gauge wheels.
The hydraulic motor on the deck is powered by a
hydraulic motor pump connected to the tractor’s PTO
shaft and is turned “ON” and “OFF” at the tractor’s PTO
shaft.
Independent Control
Refer to Figure 2-14 on page 26:
With this arrangement, the breakaway cylinder is
coupled directly to a duplex outlet at the tractor and
operated with the tractor’s hydraulic control lever.
The remaining three cylinders (“ARM 1”, “ARM 2”, and
“Deck Pivot”) are powered by a cylinder pump mounted
on the back of the motor pump. The cylinders are
solenoid activated with momentary push buttons on the
control stick.
The hydraulic motor on the deck is powered by a
hydraulic motor pump connected to the tractor’s PTO
shaft. Because the PTO shaft must run continuously to
operate the cylinders, the motor is run with an “ON/OFF”
push button switch on the control stick.
If gauge wheels are mounted on the deck, the solenoid
valve block must also include two float valves (poppet
valves) so that “ARM 2” and “Deck Pivot” cylinders can
float with the deck as it is carried by the gauge wheels.
Tractor Control
Hydraulic Hose Hook-up
Refer to Figure 2-1:
Three cylinders are connect to three duplex outlets on
the tractor. Make sure these duplex outlets have infinite
variable flow control. Do Not run tractor to make
adjustments to hose hook-up. Adjustments will be made
later during Console Control Lever Functional Checks on
page 20.
1.
Connect “ARM 1” hoses to a single duplex outlet on
the tractor. This is best if connected to the control
closest to the operator.
2.
Connect “ARM 2” hoses to the control lever next to
“ARM 1” lever. This control lever must be capable of
being placed in float position when gauge wheels are
included.
3.
Connect “Deck Pivot” hoses to the control lever next
to “ARM 2” lever. This control lever must be capable
of being placed in float position when gauge wheels
are included.

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