Operation
MOWING
Before mowing, set the cutting height as described in
the
Troubleshooting, Adjustments & Service
section.
1. Engage the parking brake. Make sure the PTO
switch is disengaged and operator is seated in
operator’s position with feet on foot rests.
2. Start the engine (see STARTING THE ENGINE).
3. Set the throttle control to FAST.
4. Disengage parking brake.
5. Extend the deck actuator fully so that the blades
are parallel to the ground. A “ratcheting” sound is
heard when the deck actuator is fully extended.
6. Engage the PTO by pulling up on the PTO switch.
7. Begin mowing.
8. When finished, shut off the PTO.
9. Stop the engine (see STOPPING THE ENGINE &
MOWER)
MOWING RECOMMENDATIONS
Several factors can affect how well your machine cuts
grass, Ferris recommends following proper mowing
recommendations to improve the performance and
life of your machine.
Height of Grass
Often cutting height is a matter of personal
preference. Typically, you should mow the grass
when it is is between three and five inches high.
The proper cutting height range for a specific lawn
will depend upon several factors, including the
type of grass, the amount of rainfall, the prevailing
temperature, and the lawn’s overall condition.
Cutting the grass too short causes weak, thin grass
plants, which are easily damaged by dry periods and
pests. Cutting too short is often more damaging than
allowing the grass to be slightly higher.
Letting grass grow a bit longer—especially when it
is hot and dry—reduces heat build-up, preserves
needed moisture and protects the grass from heat
damage and other problems. However, allowing grass
to grow too high can cause thin turf and additional
problems.
Cutting off too much at one time shocks the plant’s
growth system and weakens the grass plants.
A
good rule of thumb is the 1/3 rule: to cut no more
than one third of the grass height, and never
more than 1 inch at a time.
The amount of grass you are able to cut in one pass
is also effected by the type of mowing system you are
using (for example, broadcasting with side discharge
decks can process a much larger volume of grass
than mulching does).
Tall Grass Requires Incremental Cutting
For extremely tall grass, set the cutting height at
maximum for the first pass, and then reset it to the
desired height and mow a second or third time.
Don’t cover the grass surface with a heavy layer of
clippings. Consider using a grass collection system
and starting a compost pile.
