C23i Operating Instructions
47
Remember, anything that restricts airow or mate-
rial ow along the entire path from the mower deck
to the grass catcher can cause clogging.
Using the Tilt-Up Deck
Refer to Cleaning Grass Buildup in Mower Deck
Housing on page 63.
Using the GHS Catcher
Powerl
®
The GHS catcher has an oscillating grass delivery
spout (POWERFIL
®
) which is designed to spread
grass clippings throughout the interior of the grass
catcher (even when mowing wet, heavy grass).
The oscillating action may be checked by turning
the ignition switch to the ON (RUN) position and
moving the blade clutch (PTO) switch to the
ENGAGED position (engine not running), and
opening the catcher back door. The spout should
oscillate approximately 35 cycles per minute.
NOTE: If the grass spout fails to oscillate, the
clutch switch should be checked for function.
“Full” Signal Horn
The GHS catcher has a “full” signal horn to alert
the operator to dump the catcher when it is full
(to prevent overlling and clogging). The “full”
signal horn is activated by a vane switch (Grass-
Pak
®
switch) mounted on the grass delivery spout.
Oscil lating action of the spout triggers the vane
switch as grass begins to ll in around the spout
when the catcher is almost full.
The “full” signal function may be checked by turn-
ing the ignition switch ON (RUN), engaging the
blade clutch (engine not running), opening the
catcher back door, and triggering the Grass-Pak
®
vane by hand as it oscillates. The horn should
sound as the switch is moved in one direction.
WARNING
DO NOT test the Powerl
®
oscillation or
Grass-Pak
®
switch with the engine running.
Projectiles may be thrown out of the grass
delivery spout, and COULD cause serious
injury.
The “full” signal horn is designed to operate
(sound) when the grass catcher is almost full.
The timing of the signal is adjustable by changing
the position of the vane on the Grass-Pak
®
switch.
If the signal is coming on too soon (catcher not
completely full) or too late (grass clogging in catch-
er spout and deliv ery chute), refer to GHS “Full”
Signal Horn Adjustment on page 82.
NOTE: The horn signal should be adjusted to
sound BEFORE the catcher is completely full to
give the operator time to react and stop mowing.
An indication the horn signal is coming on too late
(de layed too much) is if grass clippings are falling
out of the grass catcher delivery chute when the
catcher is dumped.
Cleaning the GHS Exhaust Screen
To remove the grass catcher screen for cleaning,
open the catcher door, push forward and pull down
on the grass catcher screen knobs (on either side
of the screen), and slide the screen out. Use a
high pressure washer or water spray and brush to
clean the screen.
Keeping the catcher exhaust screen clean and
open is essential to good performance of the
catching system. In some mowing conditions, e.g.,
wet and dirty, it will be necessary to clean the
screen fre quently to avoid clogging the mower
deck, blower, and chutes due to airow restriction.
