unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. The triangle in text signifies important cautions or warnings which must be followed.
SAFETY DECALS
This unit has been designed and manufactured to provide you with the safety and reliability you would expect
from an industry leader in outdoor power equipment
manufacturing.
Although reading this manual and the safety instructions
it contains will provide you with the necessary basic
knowledge to operate this equipment safely and effectively, we have placed several safety labels on the unit to
remind you of this important information while you are
operating your unit.
All DANGER, WARNING, CAUTION and instructional
messages on your rider, attachments and mower should
be carefully read and obeyed. Personal bodily injury can
result when these instructions are not followed. The
information is for your safety and it is important! The
safety decals below are on your product.
If any decals are lost or damaged, replace them at once.
See your local dealer for replacements.
• Know the unit’s controls and how to stop quickly.
READ THE OPERATOR’S MANUALS.
• Read and obey all safety decals.
• Only allow responsible adults, who are familiar with
the instructions, to operate the unit.
• Disengage the PTO. Shut off the engine and wait for
all moving parts to stop before attaching, adjusting,

• Check the collection system to make sure it is bolted
tightly to the unit.
• DO NOT operate the unit without either the entire
grass catcher or the deflector in place.
• Turn off the PTO to disengage the blades when not
mowing.
• DO NOT mow in reverse. Always look down and
behind before and while travelling in reverse.
• DO NOT turn sharply when travelling alongside a
building or any object. Slow down before turning.
• DO NOT carry passengers.
• When collection system is removed from the mower
deck, the deflector must be properly installed.
• Collector bags are subject to deterioration and wear
during normal use. Inspect the bag periodically for
tears, holes, or weak spots and replace with a new
bag that meets manufacturer’s durability standards.
• If the mower stalls or the collector chute plugs:
1. Disengage the PTO;
2. Stop the engine and remove the key;
3. Set the parking brake, and wait for all moving

BEFORE OPERATION
Clear the lawn of all sticks, stones, wire and other debris
which may be caught or thrown by the mower blades.
Check grass condition. If wet, wait until later in the day.
If grass is wet, the grass catcher is likely to become
plugged.
For efficient bagging, air circulation under the
mower deck, through the chute and into the bag is
very important.
For this reason, BEFORE YOU BEGIN MOWING you
should make certain the underside of the mower and
the underside of the catcher lid are free from grass and
debris.
Make sure that there is a snug fit between mower deck,
blower housing, tubes, and grass catcher cover.
MOWING WITH THE CATCHER
Always operate with throttle at full speed when mowing.
Grass should be cut often, and not too short. If grass is
too long or lush it may be necessary to keep ground
speed to a minimum or to cut only half the width of the
mower to prevent clogging. If grass is long, operate with
mower in high cutting position for first pass, cutting again
in a lower position on a second pass.
Do not open the cover with mower engaged.
If a large amount of cut grass is spilling out from under
deck, the tube may be plugged or the bags may be full—
discontinue mowing, stop the rider, disengage the PTO,
shut off the engine and then empty the catcher or clear
the tube.
General
Operating Instructions
WARNING
ALWAYS shut off the tractor. Disengage the PTO,
and allow all moving parts to stop BEFORE
disconnecting or clearing tube, or emptying
catcher.
Before leaving the operator’s position for any
reason, engage the parking brake, disengage the
PTO, stop the engine and remove the key.
To reduce fire hazard, keep the engine, rider and
mower free of grass, leaves and excess grease.
Do not stop or park rider over dry leaves, grass or
combustible materials.
REQUIRED ACCESSORIES
A front-mounted weight carrier and approved weights are
required when using this rear-mounted grass catcher.
Never operate on slopes greater than 17.6% (10°).
AFTER OPERATION
Remove any debris from the the screen on the underside
of the lid.
Note: The lid screen can be partially removed
for easier cleaning and should be cleaned regularly.
The blower housing and tube should be removed for
cleaning.
Inspect the grass bags for wear or damage. Make sure
that there is a snug fit between mower deck, blower
housing, tubes, and grass catcher cover.
STORING THE GRASS CATCHER
Clean the grass catcher thoroughly using a mild detergent (other products may damage the tube). Remove
any debris from the the screen on the underside of the
lid.
If paint has been scratched on metal parts, touch up with
paint, or apply a thin film of oil to prevent corrosion.
Store in a dry area. Dry thoroughly before storing for a
long period of time. Always store away from moisture.

Operation &
Storage
BEFORE OPERATION
Clear the lawn of all sticks, stones, wire and other debris,
which may be caught or thrown by the mower blades.
Clean the tube with mild detergent (other products may
damage tube). Inspection windows can be removed to be
cleaned. Make sure windows are securely in place before
operating.
Check grass condition. If wet, wait until later in the day. If
grass is wet, plugging may occur.
For efficient bagging, air circulation under the mower
deck, through the chute and into the bag is very important. For this reason, you should remove grass and
debris from underside of mower deck, discharge chute
and screen inside cover.
The adapter and tube should be removed for cleaning.
Unhook the wire form and remove the tube from the
adapter. Loosen the wing nut securing the adapter to
mower deck.
If desired, the bags can be lined with 30-gallon trash
bags for easy disposal.
Inspect the grass bags for wear or damage. Make sure
that there is a snug fit between mower deck, adapter,
tubes and grass bag cover.
OPERATION
Grass should be cut often, and not too short. If grass is
too long or lush, it may be necessary to keep ground
speed to a minimum or to cut only half the width to prevent clogging. If grass is high, operate with mower in
high cutting position. Cut the grass again in lower cutting
position, if desired.
To check if grass is flowing up tube, view tube through
rear inspection window. Do not open cover with mower
engaged.
To check if grass bags are full, reach back and feel top
of right bag (left bag will fill first) or view tube through
front inspection window.
If a large amount of cut grass is spilling out from under
deck, the tube may be plugged or grass bags are full.
Shut off rider, disengage PTO and allow all moving parts
to stop before disconnecting tube.
NOTE: If mower deck is equipped with Mulching Kit, the
mulching baffles must be removed for grass collection.
Make sure the high-lift blades (packaged with the Grass
Bagger Kit) are installed (See Assembly Instructions at
the back of this manual). Standard low-lift blades are recommended for mulching operation.
Always operate with throttle at full speed.
EMPTYING THE BAGS
Raise the bagger cover. If a plastic liner was not used,
unhook the bag and turn upside down to empty (use
handle on bottom).
If plastic liner was used, first tie top of liner closed. Then,
either pull the liner out, or turn the bag upside down and
allow the filled liner to slide out.
STORAGE
Clean the grass catcher thoroughly.
If paint has been scratched on metal parts, coat with
paint or oil.
Store in a dry area. Hang the bags to dry. Always store
away from moisture.
WARNING
For safety reasons grass and debris are to be
removed from tube and adapter only after engine
is shut off, key removed and all moving parts
stopped.
WARNING
Before raising bagger cover, shut off engine,
remove key and set parking brake.
