• 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 alternator, air
cleaner, muffler and fan at minimum
speed.
• 12-volt electrical starting system with
80-amp alternator and one 12-volt,
950 cold cranking amp,
maintenance-free battery.
Transmission
Variable displacement piston pump
supplies pressure flow to low-speed
high torque hydraulic motors driving
the front and rear drums. A single
propel lever located on the control
console provides smooth hydrostatic
control of the machine’s infinitely
variable speeds in both forward and
reverse. When the propel lever is
positioned in reverse, a backup alarm
emits an audible alarm.
Speeds (forward and reverse):
Work/Travel
0-11.6 km/hr
0-7 mph
Steering
Priority-demand hydraulic power-assist
steering system provides smooth, firm
machine handling. The automotive-type
steering wheel and column are integral
with the operator’s swivel platform and
allow steering from multiple positions.

Brakes
Service Brake Features
• Closed-loop hydrostatic drive system
provides dynamic braking during
machine operation.
Secondary Brake Features
• Spring-applied/hydraulically released
brake on front and rear drums. Actuated
by switch on console or automatically
when pressure is lost in brake circuit or
when the engine is shut off. A manual
release tool is included.
Frame
Fabricated from heavy gauge steel plate
and rolled sections. The frame is joined
at the articulation pivot, 50% of the
machine is rear of the articulation pivot
and 50% is in front of the pivot. The
two sections are joined by two
hardened steel pins that are supported
by heavy-duty roller bearings. A
vertical pin provides a ±40° steering
angle and the frame/yoke provides ±4°
oscillation for a smooth ride, uniform
drum loading and no maintenance
interval.
Drum Spray System
The entire drum spray system is
corrosion resistant and includes a large
water tank with a single fill port and
drain valve.
The system consists of two diaphragm
pumps driven by electric motors. Only
one pump operates at a time, supplying
pressurized water to both sets of drum
spray bars. The pump operation is
controlled from operator’s station. The
system provides complete back-up
capability controlled from the
operator’s station.
Spray can be set on continuous for
maximum wetting action or intermittent
for maximum duration between refills.
The “Auto” selection pulls water from
one pump traveling forward, from the
other pump while traveling backward
and automatically shuts off when the
propel lever is in the neutral position.
The spray nozzles on the drum can be
easily removed for replacement or
cleaning without the need for tools.
Instrumentation
The instrument panel is located in front
of the operator and contains the
speedometer, vibe tachometer, vibration
mode selector, light switches, hour
meter, alternator indicator light, fuel
gauge, water tank gauge and warning
lights. An audible alarm sounds and a
warning light illuminates if abnormal
conditions occur in engine oil pressure,
engine coolant temperature or charge
pressure. Operational lights are also
positioned on the instrument panel.
They illuminate if the vibratory system,
drum spray system, neutral or parking
brake are engaged.
Machine controls are also located to the
operator’s right on the control console.
These controls include the start switch
with cold-start aid, electric throttle,
propel lever, speed selector switch,
automatic speed control (ASC) dial,
drum spray switch, vibration switch,
horn and secondary brake switch.
Electrical system fuses and relays are
located on the side of the control
console.
