Handle Controls - Toro 20330 - Low Wheel Walk Power Mower Service Manual

The normal or "at rest" position of the control bar is
indicated by the number 1 in the Figure 148. In order
to engage the blade, the operator must fi rst "cock" the
control bar down to position 2, then raise the control bar
to position 3.
Notice that position 3 is approximately 5" (12cm) below
the handle. This distance between position 3 and the
handle is reserved for engagement of the transmission
on those models equipped with self-propel. On units
without self-propel, the control bar can be lifted to the
handle without affecting operation of the BBC system.
After engagement of the blade, release of the control bar
disengages the blade and, on self-propel models, the
transmission. By gradually releasing the control bar, the
operator can regulate the ground speed of self-propel
models without disengaging the blade.
