Note:
Free Wheeling Or
Self-propelled Drive
The snowthrower can be free wheeled or engaged for
self-propelled operation. There are two holes in each
.
end of the axle. When axle pins are thru outer axle
holes and not thru wheel hub (Fig. 21), snowthrower
free wheels. By contrast, when both pins are installed
thru holes in wheel hub and inner hole of axle
(Fig. 21), snowthrower propels itself.

Differential Operation

For maximum maneuverability during normal snow
removal, keep differential in unlocked position. When
additional traction is needed, shift differential to lock
position.
Make sure snowthrower is not on a steep
slope or incline when performing this
procedure.
1. Move wheels to rear position (Fig. 22).
2. Shift transmission to neutral (Fig. 22).
3. Push lightly on release tab of lock spring to
disengage from shaft groove and slide coupling
to desired position (Fig. 22).
Note:
Lock position — Coupling lock spring in left hand
shaft groove (Fig. 23).
If wheels do not move in desired
direction when power shifting, repeat
procedure.
When sliding coupling from unlock
to lock position, it may be necessary
to swivel unit slightly to allow
coupling to clear differential body
bolt heads.
