Vibratory System

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 CS44B 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

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® C3.4B Engine

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.


When activated, Eco-mode reduces the operating speed of the engine to a lower rate, which reduces fuel consumption. Eco-mode can be engaged on most applications where operating conditions require normal engine power. When more power is required, Eco-mode can be deactivated to provide normal engine speed.

Dual Pump Propel System

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

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 CS44B provides high productivity when working on more demanding grades. These machines are very effective in trench applications.

The comfortable and durable seat has adjustable fore/aft position, bottom cushion height, suspension stiffness and an integrated control console for maximum comfort.

Isolated Operator's Station

The operator's station is isolated with heavy-duty rubber mounts reducing machine vibration transmitted to the operator.

Floor Mat

A floor mat helps further isolate the operator from machine vibration and noise.


Cab Environment

The cab is a spacious and comfortable work environment that includes large windows, more interior room with storage areas, a cup holder, better ergonomics and low noise levels.

Full-length Glass Windshield

The full-length glass windshield provides exceptional visibility to the drum and optional leveling blade.

Mirrors and Lights
