DESCRIPTION (figs. 1 to 10).
a. General. This tractor is of the crawler or track-laying type and
may be used for either highway or cross country travel even under the
difficult operating conditions presented by mountains, swamps, sand, or
unbridged ditches. Because of its relatively low center of gravity, the
tractor can easily climb slopes as steep as 30 degrees depending on the
kind of footing available and the load being pulled.

b. Engine. Power is supplied by a water-cooled, 3-cylinder, valve-
in-head, 2-cycle Diesel engine. A multiple speed transmission is used,

offering 4 forward speeds ranging from 2.64 miles per hour to 8.35 miles
per hour and a reverse speed of 3.14 miles per hour at full throttle

engine speed. The fuel tank has a capacity of 120 gallons which per-
mits about 20 hours of operation without refueling.

c. Steering. Steering is accomplished by means of steering clutches
operated by 2 levers mounted in the center of the tractor within easy

reach of the operator. Each lever controls a multiple disk steering
clutch through which power is delivered from the transmission to the
drive sprockets.
d. Seat. The seat has removable cushions and safety straps and will
accommodate the operator and one other man.
e. Winch. The winch is mounted on the front of the tractor and is
driven by a reversible power take-off from the tractor transmission.
A control lever for the power take-off is just ahead of the seat and in
easy reach of the operator.

f. Equipment. Equipment on the tractor includes batteries, elec-
tric starter, generator, lights, mile meter (odometer), engine air heater

and engine preheater for cold weather starting, fire extinguisher, snatch
block, tow chain, and loose tools.
g. Tractor and Engine Numbers. The serial number of the tractor
is stamped on the master clutch inspection cover, and also on the rear
