Operating Tips - Toro 30873 Operator's Manual

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.
WARNING
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.
Important: Allow engine to idle for 5 minutes before
shutting it off after a full load operation. This allows the
turbo charger to cool down before shutting the engine
off. Failure to do so may lead to turbo-charger trouble.
Before stopping the engine, disengage all controls and set
the engine speed to Slow. Setting the engine speed to Slow
reduces high engine RPM, noise, and vibration. Turn the key
to Off to stop the engine.

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.
Select the Proper Height-of-Cut Setting
to Suit Conditions
Remove approximately 25 mm (1 inch) or no more than 1/3
of the grass blade when cutting. In exceptionally lush and
dense grass, you may have to raise the height-of-cut to the
next setting.
Mow at Proper Intervals
Under most normal conditions you will need to mow
approximately every 4-5 days. But remember, grass grows at
different rates at different times. This means that in order to
maintain the same height-of-cut, which is a good practice,
you will need to cut more frequently in early spring; as the
grass growth rate slows in mid summer, cut only every 8-10
days. If you are unable to mow for an extended period due
to weather conditions or other reasons, mow first with the
height-of-cut at a high level; then mow again 2-3 days later
with a lower height setting.
Always Mow with Sharp Blades
A sharp blade cuts cleanly and without tearing or shredding
the grass blades like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which impairs
growth and increases susceptibility to diseases.
Mowing Patterns
Change mowing patterns often to minimize aftercut
appearance issues induced by repetitive operation in only one
direction.

Transporting (Groundsmaster 4700–D
Only)
Use the two rear transport latches for the outer cutting units
when transporting over long distances, rough terrain, or when
trailering.
After Operating
To ensure optimum performance, clean the underside of the
mower housings after each use. If residue is allowed to build
up in the mower housing, cutting performance will decline.
Note: Lower cutting units to the ground whenever machine
is parked. This relieves the hydraulic load from the system,
prevents wear on system parts and also prevents accidental
lowering of the cutting units.
