IMPORTANT SAFETY PRECAUTIONS
Carefully read all of the safety instructions and decals in the safety section.
This information could help you, your family, pets or bystanders avoid injury.
Training
• Regard the Bush Hog GC-250 Grass Catcher as a piece of power equipment and teach this regard to all
who operate this unit.
• Before operating your Grass Catcher, carefully read and understand this manual and the operator’s man-
ual for your mower in their entirety. Familiarize yourself with the controls and the proper use of the equip-
ment. If the operator(s) or mechanic(s) can not read English, it is the owner’s responsibility to explain this
material to them.
• Do not allow operation of this machine by untrained personnel. Never allow children, teenagers, or peo-
ple unfamiliar with these instructions to use the mower. Local regulations may restrict the age of the opera-
tor.
• Avoid mowing while people, especially children, or pets, are nearby. Keep in mind that the operator or
user is responsible for accidents or hazards occurring to other people or their property.
Preparation
• Evaluate the terrain to determine what accessories and attachments are needed to properly and safely
perform the job.
•The use of personal protective equipment, such as (but not limited to) protection for the eyes, ears, feet,
and head is recommended.
• While mowing, always wear substantial footwear and long trousers. Do not operate equipment when
barefoot or when wearing open sandals.
• Thoroughly inspect the area where the equipment is to be used and remove all stones, sticks, wires,
bones, and other foreign objects which may damage the equipment or cause personal injury to the opera-
tor or bystanders.
Operation
Although hazard control and accident prevention are partially dependent upon the design and configuration
of the equipment, these factors are also dependent upon the awareness, concern, prudence, and proper
training of the personnel involved in the operation, transport, maintenance, and storage of the equipment.
It is essential that all Operator Safety Mechanisms be connected and in operating condition prior to use for
mowing. Refer to the Operator’s Manual for the mower for additional hazard control and accident preven-
tion information.
To avoid personal injury, follow these procedures:
•
•
•
Become familiar with all operating
and safety instruction in the
•
•
Never do maintenance or repairs
while the engine is running.
Never operate the lawn mower
unless you install a mulch plate,
discharge deflector, or entire grass
collection system.
Operator’s manual for the mower
before using this attachment.
Never remove the discharge tube,
bags, bagger top or discharge
deflector while the engine is
running.
Always shut the engine off, engage
parking brake, wait for all moving
parts to stop and remove key
before clearing an obstruction from
the bagging system.

Slopes
• Use EXTREME caution when mowing
and/or turning on slopes as loss of traction
and/or tip-over could occur. The operator is
responsible for safe operation on slopes.
• Greater care must be taken as the slope
increases.
! CAUTION
• Always avoid sudden starting or stopping
on a slope. If tires lose traction,
disengage the blades and proceed slowly
down the slope.
Mowing on wet grass or steep slopes can
cause sliding and loss of control. Wheels drop-
ping over edges can cause rollovers, which
may result in serious injury, death or drowning.
To avoid loss of control and possibility of
rollover:
• Avoid sudden starts when mowing uphill.
Mower may tip backwards.
• Do not mow slopes when grass is wet.
• Do not mow near drop-offs or near water.
• Do not mow slopes greater than15 degrees.
• Be aware that loss of traction may occur
going downhill. Weight transfer to the front
wheels may cause drive wheels to slip and
cause loss of braking and steering.
• Reduce speed and use extreme caution on
slopes.
• Watch for ditches, holes, rocks, dips, and
rises that change the operating angle, as
rough terrain could overturn the machine.
• Avoid sudden turns or rapid speed changes.
• Remove or mark obstacles such as rocks,
tree limbs, etc. from the mowing area. Tall
grass can hide obstacles.
• The operating characteristics of the machine
will change with the Grass Catcher installed.
The stability and traction of the machine will
change as the Bagger fills with grass clip-
piings. Use progressively greater care on
slopes as the Bagger fills.
• Always install and remove the Bagger,
including counterweights, as instructed.
Failure to do so will cause a reduction in
stability or traction. Do not operate the
mower with only a portion of the Bagger
installed.
1. Safe Zone-use the Grass Catcher here.
2. Slope, drop-off or soft ground. Do not use
Grass Catcher here, use walk behind or
hand trimmer mower.
3. Water
Refer to the Slope Chart on page 6 to deter-
mine the approximate slope angle to be
mowed.

GC-250 GRASS CATCHER KIT
CONTENTS
1-1 Introduction
We are pleased to have you as a return Bush Hog cus-
tomer. Your GC-250 has been designed to give you a
low maintenance, simple, and effective way to collect
the grass clippings or perform spring/fall clean-up with
your Bush Hog Home Series ZT mower. This manual is
provided to give you the necessary instructions to prop-
erly mount and operate the GC-250 on your ZT mower.
Please read this manual thoroughly. Understand what
each control is for and how to use it. Observe all safety
decal precautions on the machine and noted through-
out the manual.
Note: all references made to right, left, front, rear, top
or bottom are as viewed from the normal operator's
position on the ZT mower.
Note: All work must be performed with the engine off
and the parking brake locked.
1-2 Description
The GC-250 Grass Catcher, Figure 1, is designed for
turf maintenance where there is a need to collect the
grass clippings as the ZT mower cuts the turf. It is also
good for picking up leaves and twigs in pre-season and
post-season clean-up.
Grass clippings are drawn from the discharge area of
the cutter deck up to the collection bags mounted over
the rear portion of the ZT frame. Once the bags are full
of clippings, the top of the unit can be pivoted up and
each of the two bags can be removed individually for
emptying.

You will have to cut your grass twice if it get excessively
long.
F. Remove the boot assembly from the deck by
removing the boot rod and hair pin (refer to Figure
6). Use a stick or simular object to remove the
obstruction from the mower, boot assembly or col-
lection tube.
…Bagging Long Grass
Excessively long grass is heavy and may not be pro-
pelled completely into the grass bags. If this happens,
the discharge tube and chute may plug. To avoid plug-
ging the bagging system, mow the grass at a high
height of cut, the lower the mower to your normal mow-
ing height and repeat the bagging process.
…Bagging Wet Grass
G. After the obstruction is removed re-attach the
boot assembly to the deck.
H. Resume mowing.
4-5 Removing the Grass Catcher
Always try to cut grass when it is dry because your lawn
will have a neat apperance. If you must cut wet grass,
use the conventional discharge feature of the mower.
Several hours later, when the clippings are dry, install
the grass catcher and vacuum up the grass clippings.
…Signs of Plugging
WARNING!
This machine should NEVER be in operation with
the mower discharge opening uncovered. Thrown
objects from an uncovered discharge opening
could impact the operator or bystanders resulting
in injury or death. Also contact with blade could
result in injury or death.
As you are bagging, a small amount of grass clippings
normally blow out the front of the mower. an excessive
amount of clippings blowing out indicates that the bags
are full or plugged.
Never operate this machine unless the discharge
opening is covered by the original grass deflector
or the complete grass catcher is installed.

SECTION VI
TIPS
Inspecting the Grass Catcher
Inspect the bagger attachment after the first 10 hours of
operation, and monthly thereafter.
1. Check the chute, discharge tube, and the bagger top.
Replace these parts if they are cracked or broken.
2. Tighten all nuts, bolts, and screws.
3. Under normal use the bags will deteriorate and wear.
Inspect the grass bags for deterioration.
AND
TROUBLESHOOTING
1. When the bags get full, there will be slight blowout
from the front right corner of the Grass Catcher.
Emptying the bags at this point will minimize the
potential for the tube to plug.
2. If there is excessive blowout from the deck, check to
make sure that the rear screen in the hood is clear of
grass build up. It is recommended that the screen
and mesh portions of the bags be cleaned regularly to
maintain proper air flow. This is especially important in
wet conditions.
CAUTION!
You or bystanders could be severely injured by
flying debris or thrown objects that may pass
through torn, worn or deteriorated grass bags.
•
Frequently check the grass bags for holes, rips,
wear, and other deterioration.
3. During dry conditions check engine air cleaners and
clean cooling fins more frequently. The Grass Catcher
has been designed to minimize the impact of dust and
debris on the mower, but bagging can be a dirty envi-
ronment.
•
•
Do not wash the grass bags.
If the bag has deteriorated, install new grass bags
supplied by the manufacturer of this bagger
attachment.
4 Maintaining a ground speed that does not pull down
the engine RPM will allow for the highest productivity
and best quality of cut. Bogging the engine RPM down
by going too fast will cause plugging and quality of cut
issues.
Inspecting the Mower Blades
Refer to your mower Operator’s Manual for complete
blade maintenance.
5. When storing the bagger, it is recommended that any
grass build up in the tubes be cleaned out.
Caring for the Grass Bags
Washing the grass bags is not recommended.
Under normal use the bags will deteriorate and wear. To
prevent rapid deterioration of the bag material, store the
bags where they will dry completely after each use.
Cleaning the Grass Catcher
1. After each use, remove and wash the inside and out
side of the Grass Catcher top, discharge tube, chute,
and the underside of the mower, using water sprayed
from a garden hose. Use a mild automotive detergent
to remove stubborn dirt.
2. Make sure you remove matted grass from all parts.
3. After washing, let all of the parts dry thoroughly. Do
not wash the grass bags.
