GENERAL DESCRIPTION
CONTROL LEVERS
...J
f·
The ''Allis -Chalme rs If AD Motor Graders are
available in two models: The AD-30 Motor
Grader, a 22,700 pound unit, and the AD-40
Motor Grader, a 23,000 pound unit. These
graders are designed for use in construction
and maintenance of roads, general grading, and
snow removal. The main frame is of tubular
construction to provide the utmost strength and
rigidity and to provide unobstructed vision for
the operator.
The Model AD-30.is powered with a 3 cylinder,
2 cycle Diesel Engine and the Model AD-40 is
powered with a 4 cylinder, 2 cycle Diesel Engine.
Power from the engine is transmitted through
the engine clutch to the transmission and from
the transmission to the tandem drive shafts.
The tandem wheels are driven by heavy roller
chains which connect the sprockets on the wheel
shafts with the sprockets on the tandem drive
shafts.
T he rea l' wheels of the tandem drives are
equipped v.:ith hydraulic brakes. A lever con-
trolled, disc type, mechanical brake assemb~ed
to the transmission, is provided for a pa rking
b~ake.
The transmission on leach model is co'ntrolled
by two gear shift levers which provide 6 forward
and 3 reverse speeds. At full governed engine
speed of 1600r.p.m., the forward speeds on each
model range from 2.37 to 16.64 m.p.h. and the
reverse speeds range from 2.82 to 6.13 m.p.h.
,A mechanical control box with six control levers
for operating the moldboard, front wheel lean,
and scarifier or snow plow is located directly
in front' of the operator. The moldboard can be
rotated a full 360 degrees, thereby allowing wo rk
to be done with the machine traveling backw?-r.d
as well as forward. The moldboard can be tilted
to several different pitch positions to obtain the' .
desired rolling or cutting action and can also be
shifted out to either side for cutting ditches' ~'r"
sloping banks. The front wheels can be leaned
25.5 degrees to right or left to counteract side'
draft. A HYDRAGUIDE*steering system is pro _
vided for steering the grader. The arched fr ont
axle permits the handling of heavy windrows
of dirt, gravel, or .oil mix material. Provision
is made for mounting and operating special
equipment such as a scarifier or snow plow.
