Section 2: Hydraulic Set-up Options
Options
There are two basic Hydraulic Options for the Parallel
Arm Rotary Cutter (Tractor Control Option and
Independent Control). The optional gauge wheels must
be purchased If the customer desires the deck to float. A
brief description of two options follows:
Tractor Control Option
Refer to Figure 2-3 on page 30:
Four duplex outlets are required to operate ARM1,
ARM2, DECK, 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 cylinders. If gauge wheels are included,
ARM2 and DECK 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 power take-off
shaft and is turned ON and OFF with the tractor power
take-off shaft.
For detailed set-up instructions, see
Independent Control Option
Refer to Figure 2-11 on page 35:
With this arrangement, the BREAKAWAY cylinder,
ARM1, ARM2, and DECK cylinders are powered by a
second hydraulic pump mounted on the back of the main
pump. The BREAKAWAY cylinder will release and allow
the deck and parallel arms to swing back when hit by a
solid object. Momentary ON/OFF rocker switch on the
control stick allows the operator to reset the
BREAKAWAY cylinder.
ARM 1, ARM2, and DECK cylinders are controlled with
momentary rocker switches on the control stick.
The hydraulic motor on the deck is powered by the main
hydraulic pump connected to the tractor 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 rocker switch on the control stick.
The valve block for Independent Control can be set-up
with or without float capabilities.
Valve Block Without Float Capabilities
The valve block without float capability is designed for the
operator to control deck position at all times. Gauge
wheels should not be used with this set-up.
Valve Block With Float Capabilities
If gauge wheels are mounted on the deck, the valve block
must have float capabilities. Two poppet valves are
added to the valve block to allow ARM2 and DECK
cylinders to float as the deck is carried by the gauge
wheels. The float valves are toggled on/off with a single
detent push button switch on the back of the control stick.
