Rotor Drive

Caterpillar wet clutch delivers maximum available horsepower to each ground engaging
tool while providing long service life and reliability.

Caterpillar wet clutch is the most
efficient and reliable system of applying
rotor power to the pavement. The rotor
clutch system has a separate oil sump,
pump, filter, clutch control valve and
oil cooler to provide continuous cooling
and lubrication.

Upper and lower sheave bearings are
continuously lubricated with oil from
the rotor drive clutch sump to provide
long life and reduced maintenance.

Caterpillar drum drive gear reducer
provides reliability and long service
life. An input shear shaft is provided to
protect the rotor and final drive from
overload conditions. Rotor mandrel is
liquid-filled to dissipate heat and cools
gear reducer.

Molded eleven-rib high tensile belt
provides long service life.

Automatic belt tension adjustment
prevents slipping and reduces
maintenance.

Propel System

Hydrostatic drive with hydraulic flow provided by a variable displacement piston-type
pump. Drive motors on each track provides balanced tractive effort.

Propel pump provides balanced flow to
the dual displacement drive motors on
each track. Provides superior tractive
effort on all surfaces.

Load sensing system controlled by the
ECM, matches propel speed to load on
engine for maximum production.

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

Infinitely variable machine speeds
determined by the propel lever.

Positive traction control provides equal
hydraulic oil flow to each drive motor
to increase tractive effort in hard cutting
applications.

Polyurethane track pads provide long
service life and positive traction on all
pavement surfaces.

1 Two Speed Drive Motor
2 Polyurethane Track Pads
3 Planetary w/Secondary Brake
4 Heavy-duty Cat Rollers
5 Track Frame Stops
