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 on page 23:
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 power take-off
shaft and is turned "ON" and "OFF" at the tractor's power
take-off shaft.
For detailed set-up instructions, see "Tractor Control"
on page 22.
Solenoid Control
Refer to Figure 2-13 on page 29:
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 continuous 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 power
take-off shaft and is turned "ON" and "OFF" at the
tractor's power take-off shaft.
For detailed set-up instructions, see "Solenoid Control"
on page 24.

Independent Control
Refer to Figure 2-13 on page 29:
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 power
take-off shaft. Because the power take-off 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.
For detailed set-up instructions, see "Independent
Control" on page 25.
