Operating Instructions
Avoid Low Hanging Branches
IMPORTANT:
Operate the engine at full throttle
when mowing, to allow the engine to produce full
horsepower and to increase efficiency of the engine
cooling system.
● Keep the mower deck and discharge shield clean.
● Mow with sharp blades. A dull blade tears the
grass (resulting in poor lawn appearance) and uses
extra power (slowing the mowing speed).
● It is preferable to cut grass when it is dry and not
too tall. Mow frequently and do not cut grass too
short. (For best appearance, cut off 1/3 or less of
existing grass height.)
● When mowing, operate the engine at full throttle
for the best cutting action. Mowing with a lower en­
gine RPM causes the mowing blade to not cut clean
and tear the grass. The engine is designed to be
operated at full speed.
● When mowing in adverse conditions (tall and/or
wet grass), mow the grass twice. Raise the mower
to the highest setting ­ 5 in. (127 mm) ­ for the first
pass and then make a second pass cutting to the
desired height.

● Use a slow setting on the FSC for trimming op­
erations.
● Make sure the mower is leveled properly for a
smooth cut. Refer to Deck Leveling in Assembly
Instructions.
● Use an alternating stripe mowing pattern for
best appearance and vary the direction of the stripe
each time the grass is mowed to avoid wear patterns
in the grass.
● Avoid damage to the grass by slipping and skid­
ding of the drive tires. Use smooth control move-
ments of the steering levers since the transaxles
are "power boosted controls" and jerking the levers
can easily slip the tires. For sharp turns, do not allow
the inside wheel to stop and twist on grass; pull in­
side steering lever into reverse for a smooth "rolling"
turn (one wheel rolling forward while the other rolls
back ward).
● Using the DS60 deck, or other side discharge
decks, the side discharge deflector shield must not
be removed and must be kept in the lowest possi­
ble position to deflect grass clippings and thrown
objects down ward. Orient the side discharge away
from side walks or streets to minimize cleanup of
clippings. When mowing close to obstacles, orient
the side dis charge away from obstacles to reduce
the chance of damage to property by thrown ob­
jects.

● When operating on a slope, reduce speed and
use caution to start, stop, and maneuver. Avoid
sharp turns or sudden changes in direction. The
maximum recommended slope operating angle
is 15 degrees or 26% grade.
