RCP(M)2760 & RCP(M)3760 Parallel Arm Rotary Cutter 316-548M
16
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.
RCP2760
Tractor absolute min. wt. . . . . . . . 8,000 lbs (3,630 kg)
Tractor basic min. wt. . . . . . . . . . .8,500 lbs (3855 kg)
RCP3760
Tractor absolute min wt. . . . . . . 12,000 lbs (5,445 kg)
Tractor basic min. wt. . . . . . . . . 13,500 lbs (6,123 kg)
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" (119 cm) away from the tractor center.
Tractors equipped with dual wheels may need the outside
right rear wheel removed. The RCP(M)3760 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.
RCP2760
Minimum rear wheel base . . . . . . . . . . . 74" (188 cm)
RCP3760
Minimum rear wheel base . . . . . . . . . . . 95" (241 cm)
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
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.
RCP(M)2760
Minimum horsepower . . . . . . . . . . . . . . 75 hp (56 kW)
RCP(M)3760
Minimum horsepower . . . . . . . . . . . . . . 95 hp (71 kW)
Power Take-Off Speed
RCP cutters . . . . . . . . . . . . . . . . . . . . . . . . . 540 rpm
RCPM cutters . . . . . . . . . . . . . . . . . . . . . . . 1000 rpm.
Hitch Type
Three-point hitch . . . . . . . . . . . . . . . . Cat. II or Cat III
The lower 3-point arms must be stabilized to prevent
side-to-side movement. Most tractors have sway
blocks or adjustable chains for this purpose.
Hydraulic Outlets
Tractor Control Option . . . . . . . . . Four duplex outlets
The duplex outlets are required to operate one
breakaway cylinder, two arm cylinders, and one deck
cylinder. Each cylinder is connected to a duplex
outlet and activated with the tractor control levers.
The outlets must be capable of infinite variable flow
control (turtle/rabbit control) with center detent off
levers. If gauge wheels are included, the control
levers for the outer arm cylinder and deck cylinder
must be capable of being placed in float position.
Independent Control option . . . . . . . . . . . . No outlets
A power take-off driven pump on the main frame
pumps hydraulic fluid from the reservoir to the
breakaway cylinder, two parallel arm cylinders, and
one deck cylinder. Switches on a control stick
activates the hydraulic functions as needed.
Electrical Outlets
LED lights power cord . . . . . . . . . Round 7-pin outlet
Refer to
Valve block power cord . . . . . . . .Three terminal outlet
This outlet is required for Independent Control
Option only and must be rated for 25 amps.
