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 RM300 to propel through the toughest materials

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 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.

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

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.

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 turbocharged air-to-air aftercooling system provides high horsepower with increased response time while keeping exhaust temperatures low for long hours of continuous operation.

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.

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.

Clear instrumentation includes gauges for engine oil pressure, engine coolant temperature, hydraulic oil temperature, charging system voltage and fuel level.

Large analog gauges display propel ground speed, engine rpm, engine hour meter and fault codes.

Electronic Monitoring System constantly monitors input signals from sensors and switches in various machine systems and alerts the operator if a problem does occur.

A load control selection switch controls propel speed manually or automatically by the ECM.

Standard rear wheel steering control allows operator to position rear wheels for maneuvering in tight quarters. Automatic four mode steering including a crab and coordinated position is optional.

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 radio-ready and includes a power converter, antenna with cable, two speakers and a headliner location for mounting radio.

The cab offers an exceptional viewing area to the front tire edge, mixing chamber and to the rear wheels.

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 below 1800 rpm. Machine always works at peak efficiency for maximum output.

Optional automatic rotor depth control provides consistent quality and performance.

Propel pump provides balanced flow to the dual displacement front drive motors. Provides superior tractive effort in soft underfoot conditions.

Load sensing system controlled by the ECM, matches propel speed to the load on rotor.

Two speed ranges allow the machine to operate at either maximum torque to propel the machine through the toughest conditions or a faster speed for moving around the job site.

Infinitely variable machine speeds determined by the propel lever and speed control dial.

Flow divider control valve provides equal hydraulic oil flow to each drive motor to increase tractive effort in slippery conditions.

Two propel pump system: one pump is dedicated to drive the front wheels, while the second propel pump is dedicated to drive the rear wheels.

Increased tractive effort for those tough soil or reclamation jobs.

Flow divider control valve directs equal hydraulic flow to each rear wheel to provide all-wheel drive.

High torque large displacement motors on rear wheels makes this a true four-wheel drive machine.

Large rear tires with an aggressive tread and large footprint propels the machine easily in the most severe applications.

Rear wheel drive feature can be turned on by a switch on the operator's console when maximum tractive effort is required.

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. First speed is used primarily for pulverizing the material. Second and third rotor speeds can be used as blending or mixing passes.

High capacity rotor driveshafts and maintenance-free universal joints.

Heavy-duty shear disc or optional torque limiter protects rotor drive components from torsional stress and shock loads.

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.
