Cat C4.4 Diesel Engine with ACERT™ Technology

The C4.4 engine with ACERT Technology produces 102 kW (137 hp) and meets US EPA Tier 3 engine emission requirements.

Turbocharged for Top Performance

The turbocharged engine provides efficient operation especially at high altitudes, up to 2500 meters (8,200 feet) without derating.

Balanced Power

The Pressure Override (POR) valve balances power demand in order to provide responsiveness.

ACERT Technology

ACERT Technology is a series of Caterpillar engineered innovations that provide advanced electronic control, precise fuel delivery and refined air management resulting in outstanding performance and lower emissions.

High-Capacity Cooling System

The high-capacity cooling system keeps the operating temperatures low, even in extreme conditions. The rear-mounted coolers direct exhaust air away from the operator for a more comfortable operating environment.

Comfortable Operating Environment

The console and instrumentation move with the operator, staying in the same relative position to the operator.

Multi-Position Operator's Station

The operating station has nine rotating and seven sliding positions, maximizing comfort.

Multi-Function Propel Handle

The multifunction propel handle simplifies operation with the following controls: propel speed, vibe on/off, water spray on/off, horn and optional drum offset.

Steering Console

The entire console tilts for simple entrance and exit. A lockable vandal cover is provided for the console.

Comfortable and Durable Seat

The seat has adjustable fore/aft position, suspension stiffness, and flip-up arm rests with a 76 mm (3") wide retractable seat belt.

Isolated Operator's Station

The operator's station with four, heavy-duty rubber mounts reduce machine vibration to the operator.

Automatic Speed Control

A speed control dial located on the operator's console simplifies operation by allowing the operator to preset the machine speed or impact spacing. The speed control dial allows the operator to push the propel lever to the forward or reverse positions while repeating the desired speed or impact spacing.

Excellent Visibility

The centralized station facilitates excellent visibility to the drum edges, drum surfaces and both sides of the machine. Visibility is also good to the spray bars, allowing the operator to optimize spray bar performance. External mirrors are standard.

High-Capacity Water Tank

The single, high capacity, polyethylene water tank is enclosed within the machine frame providing extended operation.

Two Pump System

An auto pump control setting selects water from one pump while traveling forward and water from the other pump while traveling rearward. The system maintains even pump usage for uniform life. Manual override control is provided.

Triple Water Filtration

Water filtration reduces machine downtime caused by system clogs. A mesh strainer is located in the water fill port. The water pump and spray nozzles, include screen filters that provide simple access and cleaning.

Nozzle Orientation

The upward spray nozzle orientation allows water to drain back into the supply line, limiting particle accumulation in the nozzle filter.

Constant or Intermittent Spray Capability

The water spray system provides constant or intermittent spray settings. The intermittent spray setting provides longer operation between fill-ups. The intermittent spray is infinitely variable allowing fine-tuning for any condition.

On/Off Spray Control

The spray control is located on the propel lever providing simple operation.

Quick Release Spray Bars Covers

Quick release spray bar covers shield the spray bars and nozzles from wind and sun, allowing the spray nozzles to provide consistent coverage across the drum surface.

Freeze Protection Kit (Optional)

The freeze protection kit includes an in-line antifreeze bottle that allows the operator to pump antifreeze into the system.

Multi-Position Seating

The multi-position operator's station provides good visibility to the drum edges, drum surfaces, water spray nozzles and overall visibility around the machine.

Folded Drum Supports

Vertically folded drum supports provide the operator with good sight lines to the drum edges when working near obstructions.

Vertical-Lift Hood Arrangement

The vertical-lift hood allows routine service when parked close to other machines and structures, providing easy ground level access to routine maintenance points.

Easy Access and Removal

The filters and spray nozzles are easily removed by hand without the need for special tools.

Sealed Hitch Design

The sealed hitch design simplifies overall machine maintenance.

Product Link Option

The machine is pre-wired at the factory for the addition of an optional Product Link system. Product Link System ensures maximum uptime and minimum repair costs by simplifying tracking of equipment fleets. The system provides automatic machine location and hour updates.

Grouped Test Ports

The hydraulic system includes grouped pressure test ports and oil sampling ports that make diagnostics easy. Test ports eliminate contamination risks.
