Toro 30631 Operator's Manual page 21

To maintain enough power for the traction unit and
implement while operating, regulate the traction pedal
to keep engine rpm high and somewhat constant. A
good rule is: decrease ground speed as the load on the
implement increases, and increase ground speed as the
load decreases.
Therefore, let the traction pedal move backward as
engine rpm decrease, and depress the pedal slowly as
rpm increase. By comparison, when driving from one
work area to another—with no load and the cutting
unit raised—have the throttle in the FAST position
and depress the traction pedal slowly but fully to
attain maximum ground speed.
Also consider the operation of the turning pedals that
are connected to the brakes. You can use the brakes to
help turn the machine. However, use them carefully,
especially on soft or wet grass because the turf may be
torn accidentally.
Another benefit of the turning brakes is to maintain
traction. For example: in some slope conditions, the
uphill wheel slips and loses traction. If this situation
occurs, depress the up-hill turn pedal gradually and
intermittently until the up-hill wheel stops slipping,
thus, increasing traction on the downhill wheel.
Use extra care when operating the machine on slopes.
Always have the seat pivot retaining pin installed. To
prevent roll overs, drive slowly and avoid sharp turns
on slopes. For steering control, the cutting deck must
be lowered when going downhill.
The grass deflector must always be installed and in
lowest position on the side discharge cutting unit.
WARNING
Careless operation, combined with terrain
angle, ricochets, or improperly positioned
safety guards can lead to thrown object
injuries.
A person or pet may suddenly appear in or near
the mowing area.
Stop mowing and do not resume mowing until
the area is cleared.
Before stopping the engine, disengage all controls and
move the throttle to SLOW. Moving the throttle to
SLOW reduces high engine rpm, noise, and vibration.
Turn the key to OFF to stop the engine.
