The shift lever is located on the handle panel
and is used to determine ground speed and
direction of travel.

There are six forward (F) speeds. Position
one (1) is the slowest and position six (6) is the
fastest.

There are two reverse (R) speeds. Position one
(1) is the slower and position two (2) is the
faster.
Chute Assembly
Snow drawn into the auger housing is
discharged out the chute assembly.

Position skid shoes based on surface
conditions. Adjust upward for hard-packed
snow. Adjust downward when operating on
gravel or crushed rock surfaces. See Skid Shoe
Adjustment section on page 12.

snow into the auger housing.

control lever so that you can operate the chute
directional control without interrupting the

lever is engaged simultaneously with the drive
control lever, the operator can release the
auger control lever (on the left handle) and
the augers will remain engaged. Release both
control levers to stop augers and wheel drive.
NOTE: Always release drive control lever
before changing speeds. Failure to do so will
result in increased wear on your machine’s
drive system.

controls are located on the underside of the
handles. Refer to Figure 3-6.
