5) FRONT WEIGHT must be installed before
operating machine with grass catcher.
6) DO NOT operate machine on slopes exceeding
10 degrees (18% grade) when equipped with
grass catcher.
7) Exercise EXTREME CAUTION on all slopes.
Turn blades off when traveling uphill. Use a
slow speed and avoid sudden or sharp turns.
8) DO NOT operate machine across face of slopes.
Operate up and down. Practice on slopes with
blades off.
9) AVOID uphill starts. If machine stops going up
hill or tires lose traction, turn blades OFF and
back slowly down the slope.
10) GRASS CATCHER COMPONENTS are subject to
deterioration during normal use. Inspect all

SECTION 1 – ASSEMBLY INSTRUCTIONS
IMPORTANT – “M” SERIES RIDERS: Series 17, “M”
model riders will require the drilling of two holes in the
front frame to install the Front Weight. Series 19, “M”
model riders already have the holes drilled but are
covered by the SNAPPER decal. Holes can be located
by rubbing lightly over decal. If you have a Series 17
rider, use the dimensions on the illustration provided to
mark the locations for drilling the two holes. See Figure
1.11.

bolt, with washer, through weight and frame.
See Figure 1.12.
STEP 6
AIR LIFT KIT, #6-0480 INSTALLATION
Some Rider models will not require the installation of
the Air Lift Kit included with the Grass Catcher. Inspect
the blade on your mower. If the blade does not have
mounting holes for the Air Lift Kit, the blade is a High Lift
version and does not require the kit. If the blade does
have the holes in the lift area of the blade, install the Lift
Kit. Installation instructions and the necessary hardware
are included with the Air Lifts.
WARNING
Blades are extremely sharp and can cause severe
injuries. Wear heavy gloves when working on or
handling blades. DO NOT use blades that show
signs of wear or damage.
WARNING
DO NOT operate machine without entire Grass
Catcher or guards in place.
STEP 7
DECK ADAPTER INSTALLATION
To install the deck adapter on certain 28” model riders,
the discharge deflector may have to be removed first.
Be careful to save the deflector and all hardware
removed for future use when not bagging.
A. Remove wing nuts, flat washers and bolts
securing deflector to side of deck. Save hardware.
See Figure 1.13.

SECTION 2– OPERATION & MAINTENANCE
INTRODUCTION
Follow operation and maintenance instructions in
the Operator’s Manual provided with the Snapper
Rear Engine Rider.
2.1 GRASS CATCHER OPERATION
A. Select desired cutting height. Choose a setting that
will not attempt to cut off too much at once,
overloading the machine.
B. After starting engine and allowing a brief warm up
period, move engine speed control to highest
setting.
C. Drive machine to cutting area. Engage blades.
D. Select a slow forward ground speed until familiar
with conditions. Do not select a speed that is too
fast, causing the machine to become overloaded.
E. The weight of the grass catcher and contents will
affect the stability and handling of the machine.
Avoid sudden starts and sharp turns. Reduce speed
on slopes, and DO NOT operate machine on slopes
exceeding 10 degrees (18% grade). Operate
machine up and down slopes. DO NOT operate
machine across the face of slopes. Turn blades off
when traveling up slope.
F. Empty grass catcher often to minimize effect on
stability and handling. Over filling the catcher will
reduce performance and cause clogging of the
tube, adapter and deck.
G. Do not operate the machine with the Grass Catcher
open. The entire Grass Catcher must be installed,
the catcher closed and latched properly before
operating.
2.2 EMPTYING GRASS CATCHER
A. Empty Grass Catcher often to avoid overfilling.
Overfilling reduces performance and causes
clogging of tube, adapter and deck.
B. Turn blades off. Drive machine to location the
clippings are to be dumped. DO NOT operate
blades in reverse. If you must back machine to
dump clippings in desired location, LOOK and SEE
behind and down for children, pets and hazards
before and while backing.
C. Shift transmission to Neutral (N). Engage Park
Brake. Stop engine. Remove key.
D. Lift up on handle sufficiently to allow all clippings to
exit catcher. If the dumped pile is too high to allow
the catcher to close, you may be required to use a
rake or similar implement to distribute the clippings.
E. After dumping, to maintain peak performance,
check the catcher screen located on the inside of
the Rear Cover Assembly to make sure it is clean
and free of any build up. Clean as required with
brush or broom.
F. Close catcher. Push down firmly on handle to
ensure it is properly latched.
G. Re-start engine and drive machine to cutting area.
Set engine speed to highest setting, engage blades
and resume operation.
DO NOT attempt to remove any clogs from deck,
adapter, or tube with engine or blade running.
STOP engine. STOP blade. Engage parking brake.
Remove key. Make sure blade and all rotating
components have come to a complete stop before
removing or unclogging any catcher component.
2.3 IF THE GRASS CATCHER BECOMES CLOGGED?
The grass catcher may become plugged if the
conditions are too severe, the catcher is overfilled, or
the machine is used improperly. If plugging does occur,
attempt the following:
1. Empty catcher more often.
2. Clean screen on Rear Cover Assembly.
3. Ground speed too fast – cut at slower speed.
4. Removing too much grass – raise cutting height, cut
partial width, and cut lawn more frequently.
5. Grass is too wet from rain or dew – allow grass to
dry.
6. Blades are dull or worn – inspect blades and
replace as necessary. Use only genuine SNAPPER
replacement blades.
7. Mower equipped with incorrect blade. Catcher
operation requires high lift blade. Contact your local
SNAPPER dealer for assistance in choosing the
correct blade for your application.
8. Deck, adapter, or tube has clipping build up – clean
all clippings from all internal surfaces.
2.4 GRASS CATCHER MAINTENANCE
Grass Catcher components are subject to wear and
deterioration during normal usage. Inspect all
components frequently for signs of wear and
deterioration. Replace worn or damaged components
immediately.
BEFORE EACH USE
A. Inspect all Catcher components. Replace all worn
or damaged parts.
B. Clean grass build up from deck, adapter, grass
tube, covers and rear cover screen. To maintain
peak performance make sure screen is clean at
each dumping.
C. Inspect blade for wear or damage. Replace as
needed.
D. Perform pre-start check list and maintenance as
instructed in the SNAPPER Rear Engine Rider
Operator’s Manual and Engine Owner’s Manual
included with the machine.
