Vibratory System

The pod-style vibratory system delivers superior compactive force while offering serviceability advantages.

Pod-style Weight Housing

The pod-style weight housing is assembled and sealed at the factory to ensure cleanliness, longer bearing life and easier field exchange or service.

Dual Amplitude

The dual amplitude works efficiently in a wider range of applications. Selection is controlled from the operator's station.

Vibratory Frequency

The CS44 has a vibratory frequency of 31.9 Hz (1914 vpm) for maximum compaction results. An optional variable frequency control allows frequency to be better matched to varying job conditions.

Large Heavy-duty Bearings

Large heavy-duty bearings for the eccentric weight shaft allow higher frequency for greater force.

3 year/3000 hour

The 3 year/3000 hour vibratory bearing lube service interval reduces maintenance.

Isolation Mounts

The heavy-duty isolation mounts on the CS44 allow more force to be transmitted to the ground and less vibration to the drum yoke.

Proprietary Eccentric Weights

Reliable dual amplitude selection and innovative design of the proprietary eccentric weights ensures precise performance.

Positive Amplitude Selection

Positive amplitude selection is accomplished when the spherical steel shot is repositioned inside the hollow eccentric weight. Direction of weight shaft rotation determines amplitude level.

Simplified Control

Control is simplified from the operator’s station with a selection switch on the operator’s console.


The proprietary eccentric weights offer high reliability since there is no chance of the high-strength spherical steel shot welding together. System reliability is superior to swinging mechanical weights and is also quieter during starts and stops.

Service Life

The proprietary eccentric weights offer long service life. There are no heavy weights to slam together and no metal fragments to contaminate the bearing lubrication system.

Cat® C4.4 Engine with ACERT™ Technology

This high-tech four cylinder engine provides outstanding durability, performance, reliability and operating economy while producing less emissions. The C4.4 engine is certified to meet U.S. EPA Tier 3 and European EU Stage IIIa emissions standards.

ACERT Technology

ACERT Technology combines proven systems with innovative new technologies to precisely shape the combustion process, providing more complete combustion of fuel and lower emissions.

More Robust Block and Components

The C4.4 has been built with a thicker engine block and more robust components, improving durability and reliability while helping to keep noise levels low. The robust design also contributes to improved cold-weather starting performance.

Engine Oil Cooler

The cooling package has been increased in size by 25%, reducing oil deterioration and varnishing of internal components as well as operating temperatures. Engine oil change interval is every 500 hours.

Low-mounted Oil Pump

The positioning of the oil pump provides quick start-up lubrication, ensuring less engine wear and a longer engine life.

Engine Certified to Meet Emissions Standards

The C4.4 engine is certified to meet U.S. EPA Tier 3 and European EU Stage IIIa emissions standards.

Dual Pump Propel System

The dual pump propel system offers high tractive effort and gradeability for outstanding productivity and machine control in demanding environments.

Dual Propel Pumps

The dual propel pumps provide separate, balanced flow to the rear wheel axle and the drum drive motors. Provides high gradeability and increases tractive effort in loose or poor underfoot conditions.

Limited Slip Differential

The limited slip differential provides balanced tractive effort and smooth torque transfer to both rear wheels.

Two Speed Ranges

The dual pump propel system offers two speed ranges for versatile operation. Low speed range for vibratory operation and maximum torque when climbing grades. High speed range moves the machine quickly over longer distances.

Flushing Valves

Flushing valves in each propel circuit help keep hydraulic oil cool and clean for maximum system efficiency.

Gradeability and Machine Control

The exclusive dual pump propel system provides superior performance, machine control and excellent grade climbing capability.

Two Propel Pump System

The two propel pump system has dedicated pumps to drive the heavy-duty, high-torque rear wheel and drum motors independently. Should the drum or wheels begin to spin, there is always hydraulic flow to the non-spinning motor, allowing continuous tractive effort. This is especially useful in loose underfoot conditions.


Controllability is another feature of dual propel pumps. The operator is able to stop, maintain machine position and change directions while on a grade.


The CS44 provides high productivity when working on more demanding grades. These machines are very effective in trench applications.

Sloped Hood Design

The sloped fiberglass hood design provides good service access and exceptional operator visibility.


Visibility to the tire edges and rear of machine is exceptional. The sloped hood allows the operator to see obstacles measuring 1 meter (3' 3") high located 1 meter (3' 3") to the rear of the machine. Excellent visibility in all directions increases productivity when working near obstructions or maneuvering around the job site.

Lockable Engine Hood

The lockable engine hood opens quickly and easily with the use of gas struts to provide good access to the engine, cooling system and all service points.

Sound Levels

Low sound levels for the operator and the ground crew due to the engine hood and cooling air flow through the rear mounted radiator.

Open Platform with ROPS/FOPS Canopy
