Track Lock Lever
The track lock lever is located on the right
side of the snow thrower and is used to
select the position of the auger housing and
the method of track operation.
To move the track lock lever, shut off the
engine. Refer to the engine operators
manual. While standing on the right side of
the unit, place your left hand on the right
handle grip. Apply a light downward force
to the right handle and use your right hand
to adjust the track lock lever to one of the
four positions.
Transport
Raises the snow thrower auger housing for
easy transport.
Snow-covered Gravel
Raises the snow thrower auger housing
so that its shave plate leaves gravel
undisturbed while clearing snow.
Normal Snow
Adjusts the tracks to be level, for full auger
housing contact with the ground.
Packed Snow
Locks the auger housing down to the ground for
hard-packed or icy snow conditions.

(F) positions or two reverse (R) positions.
Select a speed appropriate for the snow
conditions and a comfortable pace.
2.
Squeeze the drive control lever against the
handle and the snow thrower will move.

To Engage Augers
To engage the augers and start throwing snow,
squeeze the auger control lever against the left
handle. Release to stop the augers.
To Steer
(If Equipped)
With the drive control lever engaged, squeeze
the right steering trigger control to turn right.
Squeeze the left steering trigger control to turn
left.
CAUTION:
Operate the snow
thrower in open areas and at slow
speeds until you are familiar with the
drive control and comfortable
operating the steering controls.
Replacing Shear Pins
CAUTION:
NEVER replace the
auger shear pins with anything
other than OEM Part No. 738-04124A
(gold colored replacement shear
pins) or 738-05273 (Black colored
replacement shear pins). Any
damage to the auger gearbox or
other components as a result of
failing to do so will NOT be covered
by your snow thrower’s warranty.
WARNING!
Always turn OFF the
snow thrower’s engine and remove
the key prior to replacing shear pins.
The augers are secured to the spiral shaft with
shear pins (a) and cotter pins (b). If the auger
should strike a foreign object or ice jam, the
snow thrower is designed so that the pins may
shear. If the augers will not turn, check to see if
the pins have sheared. See Figure 3-8.
IMPORTANT:
ALWAYS use the correct OEM
replacement shear pin.

3-Stage Snow Throwers
•
The side augers and central accelerator
augers are secured to the spiral shaft

Clearing a Clogged Chute Assembly
WARNING!
Never use your hands
to clear a clogged chute assembly.
Shut OFF engine and remain behind
handles until all moving parts have
stopped before unclogging.
The chute clean-out tool is conveniently
fastened to the rear of the auger housing with
a mounting clip. Should snow and ice become
lodged in the chute assembly during operation,
proceed as follows to safely clear the chute
assembly and chute opening:
1.
Release both the Auger Control Lever and
the Drive Control Lever.
2.
SHUT THE ENGINE OFF! Refer to the Engine
Operator’s Manual. Remove the safety key.
3.
Remove clean-out tool from the clip which
secures it to the rear of the auger housing.
4.
Use the shovel-shaped end of the clean-
out tool to dislodge and scoop any snow
and ice which has formed in and near the
chute assembly. Always use the clean-out
tool, not your hands. Refer to the separate
supplement for clean-out tool ordering
information.
5.
Refasten the clean-out tool to the
mounting clip on the rear of the auger
housing, reinsert the safety key and start
the snow thrower’s engine.
6.
While standing in the operator’s position
(behind the snow thrower), engage the
auger control lever for a few seconds to
clear any remaining snow and ice from the
chute assembly.
