the transmission, engine speed, load on the cutting
blades or other implement components, and the
importance of the brakes.
To maintain enough power for the traction unit
and implement while operating, regulate the
traction pedal to keep the engine RPM high and
somewhat constant. A good rule to follow is to
decrease the ground speed as the load on the
implement increases, and increase the ground
speed as the load decreases.
Therefore, allow the traction pedal to move
backward as the engine RPM decreases, and
depress the pedal slowly as the RPM increases. By
comparison, when driving from one work area to
another, with no load and cutting unit raised, have
the throttle in the Fast position and depress the
traction pedal slowly but fully to attain maximum
ground speed.
The flow divider enhances traction drive
performance in compromised operating
conditions. The flow divider is for use in low speed
range only. When approaching an area known to
cause wheel spin, depress and hold flow divider
switch until completely past the area. If a tire spins
while climbing or maneuvering on slopes, depress
switch and slowly drive out of area. If both a front
and rear wheel spins, the steering brake can be
feathered to transfer the torque from the spinning
wheels to opposite front wheel.
Another characteristic to consider is the operation
of the pedals that are connected to the brakes.
The brakes can be used to assist in turning the
machine. However, use them carefully, especially
on soft or wet grass because the turf may be
torn accidentally. Another benefit of the brakes
is to maintain traction. For example, in some
slope conditions, the uphill wheel slips and loses
traction. If this situation occurs, depress the
uphill turn pedal gradually and intermittently until
the uphill wheel stops slipping, thus, increasing
traction on the downhill wheel.
Use extra care when operating the machine on
slopes. Make sure that the seat latch is properly
secured and the seat belt is buckled. Drive slowly
and avoid sharp turns on slopes to prevent roll
overs. For steering control, the cutting unit must
be lowered when going downhill.
This product is designed to drive objects
into the ground where they lose energy
quickly in grass areas. However, careless
operation, combined with terrain angle,
ricochets, or improperly positioned safety
guard can lead to thrown object injuries.
• When a person or pet appears suddenly
in or near the mowing area, stop mowing.
• 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.
Before transporting the machine, raise the cutting
units and secure the transport latches (Figure 31).

Operating Tips

Mow When Grass is Dry
Mow either in the late morning to avoid the dew,
which causes grass clumping, or in late afternoon
to avoid the damage that can be caused by direct
sunlight on the sensitive, freshly mowed grass.
