The power ratings apply at a rated
speed of 2200 RPM when tested
under the reference conditions for the
specific standard.

The net power advertised is the
power available at the flywheel when
the engine is equipped with an
alternator, air cleaner, muffler and
fan.

Derating is not required up to an
altitude of 3000 m (9850').

Cold mode starting aid, dual fuel
filters with water separator and air
compressor are standard.

Propel System

Hydrostatic drive with hydraulic flow
provided by a variable displacement
piston-type pump. Drive motors with
planetary gear reduction on each track
or wheel provides balanced tractive
effort. Machine can be equipped with
either a track or wheeled undercarriage.

Features

A variable displacement, piston-type
pump with electronic displacement
control supplies pressurized flow.

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

Drive motors have two swashplate
positions allowing operation at either
maximum torque throughout the
entire milling speed range or at a
faster travel speed for moving around
the job site.

Gear selection controlled electrically
by a two-position switch on the
operator’s console.

Infinitely variable machine speed and
direction of travel controlled by
propel lever and speed dial.

Load control system, controlled by
Electronic Control Module (ECM),
matches propel speed to load on the
engine for maximum production.

Track undercarriage – tracks are
720 mm (28.3") long, 225 mm (8.8")
wide and feature replaceable
polyurethane track pads.

Wheel undercarriage – wheels have a
diameter of 660 mm (25.9") and are
260 mm (10.2") wide.

Rotor Drive System

Operates direct through a hydraulically
actuated, dry clutch driving a planetary
gear reducer.

Features

Heavy-duty dry clutch mounts
directly to the engine. Hydraulically
actuated by a ON/OFF switch on the
operator’s console.

Mechanical dry clutch consists of
trapezoid pulleys, molded high-
strength belt and a hydraulic-coupling
dry clutch. The field-proven drive
system delivers reliability and long
service life.

A drive train protection device
protects rotor drive system, rotor and
tools by instantly disengaging rotor
drive whenever an abrupt drop in
rotor rpm occurs.

Molded six-rib high tensile strength
drive belt drives the rotor through a
drum drive gear reducer located
inside the rotor mandrel.

Hydraulically powered automatic
drive belt tensioner prevents rotor
drive belt slippage and reduces
maintenance.

Upper and lower sheaves are easily
interchangeable for maximum torque
with the toughest materials and
different material sizing
requirements.
