Operator Safety
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of
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.
GENERAL WARNING
• 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,
or disconnecting any part of the collection
system.
• 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 unless absolutely
necessary. 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.
• For added stability and to prevent tipping or loss of
control:
a. Use reduced speed on uneven ground and when
turning corners.
b. Reduce loads on hillsides. It is recommended
that the collection system be kept only half full when
negotiating any slopes. Start mowing on slopes when
the collection system is empty.
c. Mow up and down the face of slopes; never across
the face of any slope.
• Never operate on slopes greater than 17.6%
(10°).
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.
CAUTION
Before you begin operating the unit be certain you have
read all of the safety and operational information of this
instruction sheet, as well as the Operator’s Manual for
the tractor and any other attachments.
Safety Decals
Several safety labels are installed on the unit to remind you
of 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 safety
decals below are on your product.
If any decals are lost or damaged, replace them at once.
See your local dealer for replacements.
These labels are easily applied and will act as a constant
visual reminder to you, and others who may use the
equipment, to follow the safety instructions necessary for
safe, effective operation.
Attachment Decal
WARNING Thrown Objects Hazard

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 unit, disengage the PTO, shut
off the engine and then empty the catcher or clear the tube.
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.
After Operation
Remove any debris from the screen on the underside of
the lid.
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.
CAUTION
Do not leave grass in bagger containers. Empty
containers after each use and before storing. Failure
to do so may result in spontaneous combustion which
could develop into a fire.

Collector Removal
CAUTION
Operation Without Bagger
For operation without bagger, the mower deflector
MUST be properly installed in the down position.
1. Lift up cover (A, Figure 18), then remove and empty
bags (B).
2. Remove hitch and frame assembly (C) from rear of
tractor.
3. Loosen middle tube strap from lower chute (D) and
remove middle / upper tube assembly (E).
4. Lift discharge deflector (F). Rotate latch (G) upward on
front of lower chute.
5. Remove mounting strap (H) from rear bracket (I) and
pull lower chute away from mower.
Storage
Storing The Grass Catcher
Clean the grass catcher thoroughly using a mild detergent
(other products may damage the tube). Remove any debris
from 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.
