2 Productivity, Serviceability and Comfort in a Durable Package The new RM-300 offers enhanced production capabilities, optimized performance, simplified service and exceptional operator comfort. C11 Engine with ACERT® Technology ACERT® Technology works at the point of combustion to optimize engine performance and provide low exhaust emissions. The C11 engine with ACERT® Technology provides clean burning power. Electronically controlled on-demand variable speed cooling fan provides the lowest overall noise levels and high ambient operation capability. Page 4 Operator’s Station Ergonomic...

3 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 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...

4 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...

5 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...

6 Sliding Cab Optional cab can increase machine utilization and provides greater year-round comfort in extreme environment conditions. The cab is fully pressurized and includes air conditioning. Iso-mounted cab is pressurized to keep noise, dust and the elements out and comfort in. Items included with cab are: rotating cloth seat, left and right side lockable doors, tinted glass, air conditioning, heater/defroster, dual front and rear windshield wipers and sound absorbing floor mat. Additional operator comforts include two cup holders and a 12-volt power receptacle. The cab is also...

7 Electronic Control Modules Reliable field-proven technology makes machine operation simple and self-diagnostics simplifies troubleshooting. Reliable field-proven technology provides maximum productivity and simplifies troubleshooting. Electronic Control Modules (ECM) receives input signals from sensors in the engine, propel, steering and rotor drive systems which monitor current operating conditions. Self-diagnostics provides information for troubleshooting and alerts the operator of potential system problems. Automatic load control adjusts propel speed so that engine speed does not drop...

8 Rotor Drive Maximum production with high reliability. The mechanical rotor drive system provides three rotor speeds for maximum performance in a variety of materials and cutting depths. Hydraulically engaged clutch, high torque mechanical transmission and drive axle allows efficient and reliable transfer of engine power to rotor and is sized to handle tough cutting and deep mixing. Rugged drive chains provide efficient, continuous power to the rotor. Single strand heavy-duty chain resists breakage. Three rotor speeds for maximum performance in a variety of materials and cutting depths....

9 Mixing Chamber Mixing chamber is a heavy-duty hood with large volume to handle deep mixing. Ensures depth control, proper sizing and thorough blending of reclaimed materials. 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. Mid-machine rotor uses total machine weight to help keep rotor steady in the cut for uniform depth control. Bi-directional mixing capability increases machine efficiency. Large heavy-duty breaker bars help achieve uniform sizing. Hydraulically adjustable rear...

10 Rotor Selection Choice of two rotor designs for different applications and depth specifications. Tools are mounted in drive-in, knock-out holders for quick and easy replacement. Soil Rotor Designed primarily for use in soil stabilization. 238 point-attack carbide-tipped tools are mounted in drive-in, knock-out weld-on tool holders and arranged in a chevron pattern for maximum breakout force. Versatile applications – blends additives with cohesive, semi-cohesive or granular materials. Replaceable end rings protect rotor mandrel from wear. Rings are hard-faced for extended service. Maximum...

11 Serviceability Less time on maintenance means more time on the job. Hydraulic rotor hood tilt rotates hood forward for convenient access to rotor for inspection and tool maintenance. Hinged service doors open wide on sides of engine, rotor hood and on top deck for access to power train and rotor drive components. Self-lubricating rotor drive chains in sealed chain cases partially filled with oil. Electronic Control Module (ECM) monitors machine systems and provides self-diagnostics for operator or service personnel. Three warning levels alert operator to conditions on the machine that...
