Operator’s Station

Ergonomic design emphasizes comfort, visibility and easy operation. Isolated
operator’s station with heavy-duty rubber mounts reduce machine vibration
transmitted to the operator
to-side to an infinite number of positions. A switch on the side console allows the
operator to select any desired position for good visibility and comfort leading to
increased productivity.

The fully adjustable steering column and rotating seat are positioned to provide an
optimal operating position. Machine controls are grouped and conveniently located
to enhance operator productivity and reduce fatigue.

Performance and reliability you expect.

The RM-300 combines superior performance and reliability to achieve the
most demanding job specifications while maximizing machine uptime.
With many enhanced features and options, the RM-300 is designed to work
well in both full depth reclamation and soil stabilization applications.

Cab

The optional cab increases machine
utilization, provides greater year-round
comfort and of
sound levels. The pressurized cab slides
side-to-side and includes a rotating
cloth seat, left and right side doors,
tinted windows, front and rear
windshield wipers, heater/defroster and
air conditioning. Sound absorbing floor
mat reduces sound and machine
vibration transmitted to the operator.

Rotor Drive

A direct-drive mechanical transmission
drives the rotor and provides three rotor
speeds for maximum performance in a
variety of materials and cutting depths.
Heavy-duty shear disc or optional
torque limiter protects rotor drive
components from torsional stress and
shock loads.

Page 8

Rear Wheel Drive

The optional rear wheel drive propel
system features a dedicated propel
pump to provide separate balanced
hydraulic flow to both the rear drive
motors. This system enables the
operator to achieve superior tractive
effort for soil stabilization applications
that require maximum cutting depth and
that are also high in moisture content.

Page 8

Mixing Chamber

Mixing chamber allows the rotor to
move independently so that the capacity
of the chamber actually increases in
deeper cuts to allow better material
mixing and excellent gradation.
Machine weight is well distributed to
provide stability in the cut for uniform
depth control.

Rotor Options

With a choice of two rotor options, the
RM-300 can be configured for different
applications and depth specifications.
The universal rotor is intended
primarily to pulverize asphalt layers.
The soil rotor is intended primarily for
soil stabilization.

Ground level side access doors on the
rotor hood provide convenient access
for easy cutting tool removal and
replacement. Hinged side access doors
open wide for exceptional access to the
engine and cooling system. Daily
service points are accessible from
ground level and are grouped on one
side of the engine. Hinged service doors
open wide for access to power train and
rotor drive components.

C11 Engine with ACERT®Technology

A combination of innovations working at the point of combustion, ACERT®Technology
optimizes engine performance while meeting U.S. EPA Tier 3 and European EU Stage IIIa
emission regulations for off-road applications.

Cat®C11 Engine with ACERT®Technology

The C11 engine provides a full-rated
gross power (SAE J1995) of 261 kW
(350 hp) at 1800 rpm with a torque of
1384 Nm (1024 lb/ft). The combination
of large displacement and high torque
allow the RM-300 to propel through the
toughest materials.

Mechanically-Actuated Electronically
Controlled Unit Injection (MEUI)

The MEUI fuel system is a unique
system that combines the technical
advancement of an electronic control
system with the simplicity of direct
mechanically controlled unit fuel
injection. The MEUI system excels in
its ability to control injection pressure
over the entire engine operating speed
range. These features allow the C11 to
have complete control over injection
timing, duration and pressure.

Multiple Injection Fuel Delivery

Multiple injection fuel delivery involves
a high degree of precision. Precisely
shaping the combustion cycle lowers
combustion chamber temperatures,
which generates fewer emissions,
optimizes fuel combustion; translating
into more work output for your fuel
cost.

C11 Cylinder Block

The cylinder block is a one-piece, grey
iron block that features generous ribbing
for stiffness and heavy bearing
bulkheads for rigidity and strength as
the crankshaft turns. This new design
supports the engine’s higher
compression ratios and increases its
power density. The incorporation of
straight-thread, o-ring connection points
reduces the loss of engine oil and fluids.

High Cylinder Pressures

High cylinder pressures combined with
tightly controlled tolerances promote
extremely efficient fuel burn, less blow
by and lower emissions.

Single Overhead Cam

One single overhead cam is driven by a
gear on the flywheel end of the engine.
Placing the cam gear at the flywheel end
significantly reduces noise and
vibration. To reduce wear, a pendulum
absorber is mounted at the front of the
camshaft. Together these two features
contribute to the long-life and durability
of this engine.

Service, Maintenance and Repair

Easier service, maintenance and repair is
accomplished by monitoring key
functions and logging critical indicators.
Advanced electronic diagnostic
capabilities are possible using Cat
Electronic Technician.

The turbochar
system provides high horsepower with
increased response time while keeping
exhaust temperatures low for long
hours of continuous operation.

Air-to-Air Aftercooling

Air-to-air aftercooling keeps air intake
temperatures down and in concert with
the tight tolerance combustion chamber
components, maximizes fuel efficiency
and minimizes emissions. New
turbocharger, unique cross-flow head,
single, rear driven, overhead cam and a
more efficient intake manifold generate
significant improvements in air flow.
This generates significant
improvements in efficiency and reduced
emissions.

ADEM™ A4 Electr

ADEM

The
module manages fuel delivery, valve
timing and airflow to get the most
performance per gallon (liter) of fuel
used. The control module provides
flexible fuel mapping, allowing the
engine to respond quickly to varying
application needs. It keeps track of
engine and machine conditions while
keeping the engine operating at peak
efficiency.

Operator’s Station

Ergonomic design emphasizes operator comfort, visibility and easy operation. The optional
sliding platform slides side-to-side to reduce operator fatigue for increased productivity.

Hydraulically-assisted sliding platform

allows the operator to position the
platform to any desired position to
provide good visibility to both sides of
the machine. Platform can be accessed
from either side of the machine.

Comfortable and durable seat has
adjustable fore/aft position, bottom
cushion height, suspension stiffness and
flip-up arm rests. Seat and side control
console rotates to seven positions to
enhance operator comfort.

Controls are conveniently located for
easy one-handed control while seated.
