Heavy-duty double-steel-reinforced rubber tracks last longer than those on other machines. Easy-clean
undercarriage shortens end-of-day cleanout and reduces track wear due to dirt buildup.
Drive motors are heavy duty, and hoses are shielded for extra protection. Direct-mounted planetary fi nal
drives employ larger-than-usual bearings for one-of-a-kind reliability.
Spring-applied, hydraulic-released wet-disc park brakes are fully enclosed and never require adjustment.
O-ring face-seal hydraulic fi ttings virtually eliminate aggravating and costly oil leaks.
Switches and electrical connectors are sealed from moisture and dirt to help prevent corrosion.
Auto-shutdown system monitors engine and hydraulic vitals, and issues an audible warning when limits
are exceeded. If necessary, it shuts down the machine to help prevent damage.
1. Industry-exclusive design separates
coolers in an innovative V-shape
confi guration that’s 20-percent more
effi cient. Large aluminum hydraulic
cooler and radiator provide the
necessary cooling capacity for high-
ambient-temperature operation.
2. Hydraulic-driven variable-speed fan
runs only as fast or as frequently as
needed for improved power and
fuel effi ciency. Decreases noise and
debris fl ow through the coolers, too.
There’s also an exclusive fan option
that reverses automatically every 20
minutes, or at the click of a switch, to
clear core-clogging buildup.
3. All-steel rollers, idlers, and sprockets
are similar to those used on our highly
durable larger crawlers. Metal-face
seals and journal bearings further
increase longevity.
