Operating Characteristics
Practice driving the machine because it has a hydrostatic
transmission and its characteristics are different than many
turf maintenance machines. Some points to consider when
operating the traction unit, cutting unit, or other implements
are 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
1
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
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 (Fig. 30).
