Engine

Proven Cat engines provide the power and torque rise for excellent lugging in tough loading conditions.

Fuel System

The fuel system and Electronic Control Module on the C18 tractor engine economically and precisely deliver fuel.

Injection Pressures

High injection pressures, independent of engine speed, decrease smoke and emissions while improving response.

Variable Injection Timing

Variable injection timing and duration improve fuel efficiency and cold starting, decrease smoke and emissions.

Injection Rate Shaping

Injection rate shaping reduces emission and engine noise.

Mechanical Parts

Fewer mechanical parts in the fuel system improves reliability.

Electronic Control

Electronic control provides automatic altitude deration and automatic air filter restriction deration.

Multiple Horsepower Ratings

Multiple horsepower ratings limit output in first and second gears.

Neutral Start Control

Neutral start control prevents engine from starting unless transmission is in neutral.

Throttle Back-up

Throttle back-up provides the operator with a preset engine speed control in the event of a throttle input failure.

Throttle Lock

The throttle lock allows the operator the capability of locking both engines at any operating level.

Directional Shift Management

Directional shift management prevents the operator from shifting out of neutral when engine rpm is above a preset level.

Controlled Throttle Shifting

Controlled throttle shifting increases drive train life by reducing the fuel injection rate just prior to shifting.

Automatic Ether Starting Aid

Automatic ether starting aid greatly improves cold weather starting.

Electronic Ground Level Shutoff

Electronic ground level shutoff enables the operator to stop the engine from the ground with the flip of a switch.

Steel Spacer Plate

Steel spacer plate between the block and head eliminates the need for counterbores and helps prevent associated cracking problems.

Oil-Cooled Pistons

Oil-cooled pistons and full-length water-cooled cylinder liners provide maximum heat transfer for longer component life.

Aftercooler

The aftercooler lowers intake charge air temperature to increase power and reduce thermal stresses that can cause premature wear of pistons, rings, and liners.

Engine Oil Cooler

Engine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.

Laminated Thermo-Shield

Laminated thermal-shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, extends hose and wiring life.

Standard Hydraulic Retarder

An optional hydraulic retarder can extend brake life.

Transmission

Eight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation.

Neutral Coast Inhibitor Control

Neutral coast inhibitor control helps prevent the transmission from shifting to neutral at speeds above 8.1 km/h (5 mph).

Top Gear Control

Top gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.

Electronic Programmable Transmission Control (EPTC II)

Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.
