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. The hydraulically assisted platform slides side-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.
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-500 combines superior performance and reliability to achieve the
most demanding job specifications while maximizing machine uptime.
With many enhanced features and options, the RM-500 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 offers reduced interior
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.
Page 6
Dual Propel Pumps
The dual pump propel system provides
separate balanced hydraulic flow to
both the rear drive motors and the front
drive motors to propel the machine with
full-time all-wheel drive. 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 7
Rotor Drive
A Caterpillar® powershift 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
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.
Page 9
Rotor Options
With a choice of three rotor options, the
RM-500 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. The combination rotor
is intended primarily for use in soil
stabilization with secondary application
in light cuts of asphalt reclamation.

Serviceability
The one-piece fiberglass hood tilts
forward 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 ground level
side panels allow total engine access.
Hinged service doors open wide for
access to power train and rotor drive
components. The rotor hood tilts
forward to allow access to the rotor and
cutting tools. Ground level side access
doors on the rotor hood provide
convenient access for easy cutting tool
removal and replacement.

C15 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.
Turbocharged and Air-to-Air
Aftercooling (ATAAC)
The turbocharged air-to-air aftercooling
system provides high horsepower with
increased response time while keeping
exhaust temperatures low for long
hours of continuous operation.
Cat® C15 Engine with ACERT Technology
The C15 engine provides a full-rated
gross power (SAE J1995) of 403 kW
(540 hp) at 2000 rpm with a torque of
2356 Nm (1738 lb/ft). The combination
of large displacement and high torque
allow the RM-500 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 C15 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 and
optimizes fuel combustion, translating
into more work output for your fuel
cost.
4
C15 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.
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, front driven, overhead cam and
a more efficient intake manifold
generate significant improvements in
air flow. This generates significant
improvements in efficiency and reduced
emissions.
High Cylinder Pressures
High cylinder pressures combined with
tightly controlled tolerances promote
extremely efficient fuel burn, less blow
by and lower emissions.
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.
ADEM™ A4 electronic Control Module
The ADEM A4 electronic control
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 platform
slides side-to-side to increase versatility and productivity while reducing operator fatigue.

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 positioning, 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.
Propel lever with center detent allows
forward/reverse operation and variable
machine speed.
The side console features a padded arm
rest, the four mode steering switch,
speed control dial, propel lever, rotor
elevation, front and rear rotor hood
door switches, rear steering switch and
sliding operator’s station switch.
Adjustable steering column offers
telescoping and tilt features to provide a
comfortable operating position for the
operator.
