Weight
WARNING
!
To avoid serious injury or death:
Lightweight tractors with rear attached implements may need
weights added to the front to maintain steering control.
Consult your tractor Operator’s Manual to determine proper
weight requirements and maximum weight limitations.
Absolute Minimum: Tractor weight must be sufficient to
control the Parallel Arm Rotary Cutter under all operating
conditions. Tractors not meeting the absolute minimum
weight listed below must not be used.
Basic Minimum: A right-hand overturning torque load is
present on the tractor when parallel arms are fully
extended. Tractors will need auxiliary counterbalance
weights added if the tractor’s total weight is less than the
absolute minimum weight. It is best to add auxiliary
weights to the left rear tractor wheel. Up to eight 100 lb.
suitcase type weights can be added to the optional
hydraulic reservoir weight hanger. Adding weights to the
reservoir will lighten the tractor’s front end.
RCP2660 & RCPM2660
Tractor absolute minimum weight . . . . . . . . 8,000 lbs.
Tractor basic minimum weight. . . . . . . . . . . 8,500 lbs.
RCP3060 & RCPM3060
Tractor absolute minimum weight . . . . . . . 12,000 lbs.
Tractor basic minimum weight. . . . . . . . . . 13,500 lbs.
Wheel Base
Refer to Figure 1-1 & Figure 1-2:
The front gauge wheel and mount may interfere with the
right rear tractor tire when deck is folded for transporting.
This is especially true if the outside face of the tire is
more than 47" away from the tractor center. Tractors
equipped with dual wheels may need the outside right
rear wheel removed. The RCP(M)3060 cutter requires a
dual wheel on the left-hand side or wheel weights equal
to the weight of a dual wheel.
Rear wheel base must meet minimum requirements
when measured from outside face to outside face of rear
tractor tires. Smaller wheel bases must not be used.
RCP2660 & RCPM2660
Rear Wheel Base . . . . . . . . . . . . . . . . . . 74" minimum
RCP3060 & RCPM3060
Rear Wheel Base . . . . . . . . . . . . . . . . . .95" minimum
IMPORTANT: Extended parallel arms will pull the
tractor’s front to the right. When necessary, add
weight to the tractor front to stabilize it. Consult your
tractor’s manual for allowable added weights.
The tractor’s right rear wheel should be pressurized
to the manufactures highest recommended air
pressure.
Tractor Requirements
Horsepower
Tractor horsepower must be capable of controlling the
Parallel Arm Rotary Cutter under all operating conditions.
Smaller tractors must not be used.
RCP2660 & RCPM2660
Horsepower Range. . . . . . . . . . . . . . . 75 minimum hp
RCP3060 & RCPM3060
Horsepower Range . . . . . . . . . . . . . . 95 minimum hp
Power Take-Off Speed
The RCP cutters requires 540 rpm power take-off speed
and the RCPM cutter requires 1000 rpm power take-off
speed to operate the hydraulic pump(s) & motor.
Required tractor horsepower to operate the pump(s) and
motor is approximately 30 hp.
Hitch
A 3-point Category II or Category III hitch is required. The
lower 3-point arms of the 3-point hitch must be stabilized
to prevent side-to-side movement. Most tractors have
sway blocks or adjustable chains for this purpose.
Hydraulic Outlets
The number of tractor hydraulic duplex outlets required is
dependent upon how the Rotary Cutter is set-up.
Independent Control:
One duplex outlet is required to operate the breakaway
cylinder. A power take-off driven pump on the unit pumps
hydraulic fluid from the reservoir to the parallel arm
cylinders and deck pivot cylinder. The cylinders are
solenoid activated with momentary push button switches
at the control stick.
Solenoid Control:
Two duplex outlets are required. One duplex outlet is
required to operate the breakaway cylinder. The second
duplex outlet operates the parallel arm cylinders and
deck pivot cylinder. The cylinders are solenoid activated
with momentary push button switches at the control stick.
The second duplex outlet must be capable of continuous
hydraulic fluid flow.
Tractor Control:
Four duplex outlets are required to operate the parallel
arm cylinders, deck pivot cylinder, and breakaway
cylinder. Each cylinder is connected to a duplex outlet
and activated with tractor control levers. Each duplex
outlet must be capable of infinite variable flow control
(turtle/rabbit control) with center detent “OFF” levers. If
gauge wheels are included, “ARM 2” and “Deck Pivot”
levers must be capable of being placed in float position.
