Removing
POTENTIAL
the Grass Catcher
HAZARD
• Sometimes people are tempted to operate
the mower without both grass bags
installed on the Twin Bagger or with the
discharge chute or duct removed. This
exposes you and others to thrown debris
and blade contact.
WHAT CAN HAPPEN
• You and others may die or be injured
severely if you are hit by thrown debris or
cut by the blade.
HOW TO AV
OID THE HAZARD
• Always operate the mower with either the
complete grass catcher mounted in place or
use the mower to side discharge, making
sure that the spring-loaded grass deflector
is in the down position.
1. Disconnect the retainer on the duct from the
knob on the chute and pull the duct free from the
chute and grass bagger (Fig. 4)

Operation
To Avoid Personal Injury:
• Become familiar with all operating and
safety instructions in the operator’s manual
for your mower before using this
attachment.
•
Never r
the discharge chute while the engine is
running.
emove the duct, bags, bag cover, or
• Always shut the engine off before clearing
an obstruction from the bagging system.
• Never do maintenance or repairs while the
engine is running.
Emptying
Grass bags can weigh up to 90 lb (41kg) when full.
Be careful when lifting or handling a grass bag that is
full. To empty the grass bags:
1. Stop the mower, shift to NEUTRAL, and move
the blade control to DISENGAGE (this stops the
mower blades). Shut the engine off before you
get off the mower.
the Grass Bags
Clearing
Obstructions
From Bagger
1. Stop the mower and shift to NEUTRAL.
2. Raise the mower housing to the highest possible
position and slap the side of the duct near the
obstruction.
If the obstruction does not clear, complete the
following:
3. Move the blade control to DISENGAGE (this
stops the mower blades). Shut the engine off
before you get off the mower.
4. Check the grass bags and empty them if they are
full.
5. Remove and separate the duct and chute from
the bag cover and mower. Using a stick or
similar object, carefully remove and clear the
obstruction from the mower, duct, chute, and the
bag cover.
6. After you remove the obstruction, install the
complete bagger and resume operation.
2. Squeeze the bag handles and swing the bag
down from the bag frame bracket.
3. Compress debris into the bags. With both hands,
pull the bag out from under the bag cover.
Empty the bag.
4. Repeat steps 2 and 3 for the other bag.
5. Slide the grass bag under the bag cover and
position the front edge of the bag rod into the
screen support bracket on the bag frame (Fig. 6).
6. Lift the rear of the bag up to the bag cover.
Squeeze the bag handles and allow then to snap
into the bag frame brackets (Fig. 7).
7. Repeat steps 5 and 6 for the other bag.
Operating
Size
Remember that the mower is longer and wider with
this attachment installed. By turning too sharply in
confined places you may damage the attachment.
Trimming
Always trim with the left side of the mower. Do not
trim with the right side of the mower because you
could damage the discharge chute and duct.
Cutting Height
Do not set the mower cutting height too low because
long grass surrounding the mower can prevent air
and Bagging T
ips

Operation
from getting under the mower and entering the
bagging system. If enough air doesn’t get under the
mower, the bagging system will plug.
Cutting Frequency
Cut the grass often, especially when it grows rapidly.
You will have to cut your grass twice if it gets
excessively long (refer to Bagging Long Grass,
page 8).
Cutting Technique
For best lawn appearance, be sure to slightly overlap
the mower into the previously cut area. This helps
reduce the load on the engine and reduces the chance
of plugging the bagging system.
Using Bags
Although not required, bags may be inserted into
each cloth grass bag as a liner to collect clippings and
make disposal more convenient (Fig. 8). If you use a
bag liner, remove the filled grass bag and close the
top of the liner. Then pull the liner out the grass bag
or turn the bag upside down while holding the handle
on the bottom of the grass bag (allows liner to slide
out).
speed. The bagging system may plug if you drive too
fast, causing the engine to slow down with the extra
work load.
POTENTIAL HAZARD
• As the grass bags fill, extra weight is added
to the back of the mower.
WHAT CAN HAPPEN
• If you stop and start suddenly on hills, you
may lose steering control or the mower may
tip.
HOW TO AV
OID THE HAZARD
• Do not start or stop suddenly when going
uphill or downhill. Avoid uphill starts.
• If you do stop the mower when going
uphill, move the blade control to
DISENGAGE (stop the mower blades).
Then back down the hill using slow reverse
speed.
• Do not change speeds or stop on slopes.

Bagging Speed
Most often you will bag with the tractor throttle in the
FAST position and drive in 1st gear, which is the
slowest ground speed. However, in extremely dry and
dusty grass, you may want to lower throttle speed and
shift gear selector to a higher gear to maintain ground
Bagging Long Grass
Excessively long grass is heavy and may not be
propelled completely into the grass bags. If this
happens, the discharge tube and elbow may plug. To
avoid plugging the bagging system, mow the grass at
a high height-of-cut, then lower the mower to your
normal cutting height and repeat the bagging process.
Bagging W
et Grass
Always try to cut grass when it is dry because your
lawn will have a neat appearance. If you must cut wet
grass, use the conventional side discharge feature of
the mower. Several hours later, when the clippings are
dry, install the complete bagger attachment and
vacuum up the grass clippings.
Signs of Plugging
As you are bagging, a small amount of grass
clippings normally blow out the front of the mower.
An excessive amount of clipping blow-out indicates
that the bags are full or the system is plugged.

Maintenance
Inspecting
the Bagger
Attachment
Inspect the bagger attachment after the first ten hours
of operation, and monthly thereafter.
1. Check the duct, chute, and the bag cover.
Replace these parts if they are cracked or broken.
2. Tighten all nuts bolts and screws.
3. Inspect the grass bags for deterioration.
POTENTIAL HAZARD
• The grass bag material may tear, wear, and
eventually deteriorate.
WHAT CAN HAPPEN
• You or bystanders could be severely injured
by flying debris or thrown objects that may
pass through worn or deteriorated grass
bags.
HOW TO AV
• Frequently check the grass bags for holes,
rips, wear, and other deterioration. Do not
wash the grass bags. If the bag has
deteriorated, install new grass bags
supplied by the manufacturer of this
bagger attachment.

Caring
1. Washing the grass bags is not recommended.
2. To prevent rapid deterioration of bag material,
POTENTIAL HAZARD
• If you store grass clippings in the grass
bags, under the right conditions,
spontaneous combustion (a fire-generating
process that occurs without an external
source of ignition) could occur.
WHAT CAN HAPPEN
• If a fire occurs, property could be damaged
and/or someone could be injured.
HOW TO AV
• The cloth grass bags are not storage
containers. Never store grass clippings and
debris in the grass bags.
Cleaning
for the Grass Bags

use.
OID THE HAZARD
the Bagger
Attachment
1. After each use, remove and wash the inside and
outside of the bag cover, duct, chute, and the
underside of the mower, using water sprayed
from a garden hose. Use a mild automotive
detergent to remove stubborn dirt.
1. Inspect the mower blades regularly and
whenever a blade strikes a foreign object.
2. If blades are badly worn or damaged, install new
blades. Refer to your mower operator’
for complete blade maintenance.
