13 RM-300 specifications
Propel System
Front wheel drive is standard. Rear
wheel drive is optional to provide on-
demand all-wheel drive for increased
tractive effort. Operator can activate by
a switch on the front control console.
Features
■ Front wheels are hydrostatically
driven by two dual displacement
piston-type motors. A separate
variable displacement, piston-type
pump with electronic displacement
control supplies pressurized flow.
Planetary gear reduction on each
front wheel end.
■ Front drive motors have two
swashplate positions allowing
operation at either maximum torque
for work or greater speed for moving
around the job site.
■ Gear selection controlled electrically
by a two-position switch on the
operator’s console.
■ Rear wheels are hydrostatically
driven by two radial piston-type
motors. A separate variable
displacement, piston-type pump with
electronic displacement control
supplies pressurized flow.
■ Infinitely variable machine speed and
direction of travel controlled by
propel lever.
■ Speed control dial allows the operator
to set the maximum working speed so
that when the propel lever is placed in
the full forward position, the machine
will return to the pre-set speed.
■ Load sensing system, controlled by
Electronic Control Module (ECM),
matches propel speed to load on the
rotor.
■ Flow divider control valve provides
equal hydraulic oil flow to each drive
motor to increase tractive effort in
slippery conditions. Operator can
activate by a switch on the front
control console. The rear propel
system also includes a flow divider
control valve if machine is equipped
with the rear wheel drive option.
Max. speeds (forward and reverse):
Working 4.3 km/h - 2.7 mph
Roading 9.7 km/h - 6.0 mph
Rotor Drive System
Operates direct through a hydraulically
actuated clutch driving a mechanical
transmission.
Features
■ ON/OFF switch controls
hydraulically actuated clutch driving
transmission and rotor drive axle.
■ Three rotor speeds are created through
transmission and rotor drive axle.
Choice of rotor speeds permits
working in a wide range of materials,
depths and applications.
■ Rotor speed selection controlled
electrically by a three-position
switch on the operator’s console.
■ Single strand, high strength rotor
drive chains on both sides are
contained in heavy-duty chain cases
partially filled with oil.
■ Shear disc or optional torque limiter
protect rotor drive components.
Rotor Speeds (@ 1800 engine rpm):
First 106 rpm
Second 144 rpm
Third 216 rpm
Rotor Depth Control
Manual rotor height and depth
controlled by operator is standard.
Automatic rotor height and depth is
optional and features electronic over
hydraulic control. ECM controls two
double-acting hydraulic cylinders on
sides of mixing chamber. Actual rotor
height and depth are displayed on the
electronic control panel.
Features
■ Three-position mode switch allows
rotor depth to be controlled manually or
automatically.
■ MANUAL mode controls depth using
the raise/lower switch. Visual depth
gauge easily seen from operator’s
station.
■ AUTOMATIC mode automatically
controls rotor depth to a preset cutting
depth. Setting cutting depth is easily
accomplished first in manual mode by
a switch on the operator’s console.
■ TRAVEL mode selection automatically
raises rotor and hood to a preset travel
height.
Brakes
Primary Brake Features
■ Closed-loop hydrostatic drive
provides dynamic braking during
normal operation.
Parking Brake Features
■ Spring-applied/hydraulically-released
multiple disc type brake mounted on
each gear reducer. Secondary brakes
are activated by a button on the
operator’s console, loss of hydraulic
pressure in the brake circuit or when
the engine is shut down.
■ Propel pumps are destroked when
parking brake is engaged. Propel
lever must be returned to neutral after
brake is released before machine will
propel.
Steering
A hydraulic power-assist, two mode
steering system—front and rear wheel
is standard. Four mode features crab
and coordinated steering through ECM
is optional.
Features
■ Two double-acting steering cylinders
control the front wheels and are
powered by a pressure-compensated,
piston-type pump. One double-acting
steering cylinder is attached to the
rear bolster. Constant pressure is
assured in the steering system.
■ Switch on operator’s side console
provides rear wheel steering mode.
Steering Modes
■ Front steer only—controlled by a
hand metering unit, maintained by
closed-loop control. When equipped
with four mode steering, ECM
automatically aligns rear wheels to the
center position for straight tracking.
■ Rear steer—controlled by a toggle
switch, maintained by closed-loop
control.
■ Crab—front and rear wheels turn
simultaneously in the same direction.
■ Coordinated—front and rear wheels
turn simultaneously in the opposite
direction.
■ Switch on operator’s side console
provides four steering modes.
Turning Radius (minimum):
Inside 3.9 m (12' 10")
