General Information

The Grass Handling System (GHS) consists of a rear
discharge mower deck connected to a 9 in. (23 cm)
blower and a rear mounted grass catcher with 6.7
bushel (238 liters) capacity. The GHS blower oper-
ates any time the mower blade clutch is engaged and
moves grass through the rear discharge deck chute
into the grass catcher. Blower airflow is exhausted
out the back of the grass catcher, through a filtering
screen. When the grass catcher is full and needs to
be emptied, a "full" signal horn alerts the opera-
tor. When the "full" signal horn sounds, it is important
to stop mowing to prevent overfilling and clogging of
the blower system.
IMPORTANT: Normally, the GHS blower operates
with no maintenance or cleaning required. However,
under certain operating conditions, the inside of the
blower housing may accumulate a deposit of dirt,
causing wear and binding of the blower wheel. Nor-
mally, dirt buildup occurs when mowing a
combination of dirty and damp grass, especially
in the springtime. When operating in these condi-
tions, check the blower wheel frequently for
binding and clean the blower housing as required.
Refer to CLEANING the GHS Blower in Mainte-
nance Instructions .
NOTE: In Autumn, when using the GHS mower to
vacuum leaves, it is recommended to raise the front
of the mower deck 2 to 3 notches [1 to 1-1/2 in. (25
to 38 mm)] higher than the rear. This will avoid
"bulldozing" leaves, particularly when the leaves
are piled in a thick layer. To make this adjustment,
the hitch pins in the two (2) front deck support pins
are repositioned 2 to 3 notches higher while leaving
the rear pins in their original position.
NEVER operate the GHS catcher with the
back door open. Objects may be thrown
out the back of the catcher with sufficient
force to cause serious injury to bystanders
or to damage property.
DANGER
NOTE: When a side discharge or mulching mower
deck is installed on the GHS model, a blower intake
cover should be installed in the blower intake tube.
This cover "unloads" the blower and seals the intake
to effectively eliminate power loss and blower noise
when the blower is not being used.

DANGER
ROTATING BLOWER BLADES
NEVER operate the GHS blower with the
blower discharge chute uncovered (grass
catcher in the dump position) since dan-
gerous projectiles may be thrown. NEVER
put hands into the blower discharge chute
for any reason. Use a stick or similar in-
strument to remove any material if clog-
ging has occurred.
CAUTION
NEVER leave grass clippings in the grass
catcher after mowing. Damp clippings
generate heat as they decompose. This
MAY cause spontaneous combustion.
