Drive System; Operation - Toro Snow Commander Service Manual

Operation

A multigrooved V belt transfers power from the engine
pulley to the rotor drive pulley. Belt clutching is
controlled by a cable connected to a bail on the upper
handle. When engaged, the combination idler/brake
arm rotates to disengage the brake and move the idler
to tighten the belt (Figure 36). When the bail is
released, a spring pulls the idler away from the belt and
engages the rotor brake. See Figure 46 for location of
spring.

The same control bail on the handle has a second
cable attached to it. This cable controls tilting of the
powerhead (Figure 37).

When the bail is squeezed, the powerhead containing
the engine and rotor is tilted forward until the rotor
blades contact the surface. This action provides a self-
propelling action by the rotor blades as well as cleaning
down to the surface (Figure 38).
