Flush-fit bottom guards and tight-fitting<br />
side shields help keep trash out. Hood<br />
and side-shield perforations function as<br />
a “first filter,” further preventing entry of<br />
most debris. Anything that gets past the<br />
five-mm holes also passes through the<br />
cooler cores.<br />
Available extended-life undercarriage<br />
delivers up to twice the bushing life, for<br />
extra durability in extremely abrasive<br />
conditions. If you want to further reduce<br />
maintenance and operating costs, choose<br />
the SC-2 extended-life option.<br />
Individually replaceable wet-sleeve enginecylinder<br />
liners provide uniform engine<br />
cooling and long-term durability.<br />
Reversing fan (standard on 750K and 850K)<br />
automatically back-blows the cooler cores<br />
at preset intervals. When conditions demand<br />
more frequent cleaning, simply press a<br />
button to actuate the reversing cycle.<br />
Variable-speed on-demand fan automatically<br />
speeds up or slows down,<br />
operating only as needed to keep things<br />
cool. Helps conserve power and fuel,<br />
while reducing noise.<br />
One-piece welded mainframe resists<br />
torsional stress, absorbs shock loads, and<br />
delivers maximum strength while allowing<br />
easy service access to major components.<br />
Heavy-duty double-reduction planetary<br />
final drives are mounted independent of<br />
the track frames, where they’re effectively<br />
protected from shock loads.
