*CHECK oil level in 4-cycle engines and add oil as
needed to bring the level up to but not over the
dipstick (15) "FULL” mark. Refer to FIG. 2.
* CHECK cutting height and adjust as needed, to suit
the prevailing grass conditions. Refer to FIG. 5.
*CHECK fuel level in tank after pushing mower out-
doors where fumes will safely dissipate. On 2-cycle
engines, use the correct fuel to oil ratio as specified
in the engine manual.

while moving around behind the UPPER HAN-
DLE to the Operator's position.
CUTTING HEIGHT ADJUSTMENT
| ALWAYS STOP THE ENGINE AND WAIT UNTIL THE
MOWER'S BLADE STOPS COMPLETELY BEFORE
RE-ADJUSTING CUTTING HEIGHT!
To re-adjust mower cutting height, pull each of the |
four height ADJUSTING LATCHES (1) outward
toward the wheel and then slide into the desired
notch. Set both latches on one side and then set the |
two on other side into corresponding notches. When
setting the rear latches into LOWER notches, raise
the rear wheels off the ground to ease procedures.
It is recommended that no more than 1/3 the height or 2"
maximum be cut from the grass.
EXAMPLE: If the grass is 4” tall, set the four AD-
JUSTING LATCHES (1)
blade setting) which will leave the grass at approx-
imately 3” tall after cutting -well within the 1/3 off
limit. If you prefer shorter grass, wait a few days '
before recutting at a lower setting. If cut short too
frequently, the root system will be more subject to
burning, due to energy being expended toward the
development of new leaf structures rather than the
necessary development and reinforcement of a good
healthy root system!
If allowed to grow too tall, the lower portion (which
will then be shaded) will discolor.
During dry seasons, allow the grass to grow taller
than normal. Refer to FIG. 5-A.
RECYCLING OPERATION
For best resuits when recycling, set the cutting
height in notch 5 (highest blade setting) or notch 4
and mow with the engine speed control in fastest
speed setting. Operate the mower at slowest ground
speed to allow fine chopping of the clippings or
leaves. The grass must be dry. If the grass is ex-
tremely dense, set the front height adjusters one
notch lower than the rear adjusters to raise the front
of the deck. Experiment with deck settings to
achieve best recycling.
MOWING PROCEDURE
Set the ENGINE CONTROL lever (10) in the fast (F)
position for thick grass, AND slow down (reduce
“Ground Speed") OR narrow the cut to less than the full
blade width.
NOTE: It is recommended that the ENGINE CON-
TROL lever be set in the "FAST" position (higher
RPM’s when recycling.
On self-propelled models, set the GROUND SPEED
CONTROL lever (12) in the desired setting and
then grasp the WHEEL DRIVE CONTROL (19) and
hold against the UPPER HANDLE (18) to engage
clutch. To stop the mowers forward movement,
release the WHEEL DRIVE CONTROL - the mower
can then be pushed forward or pulled for trimming.
Experiment and adjust the ENGINE CONTROL lever
and the GROUND SPEED CONTROL until the mower
functions best for your turf conditions. The speed of
forward movement can be varied while the mower is
moving by changing the GROUND SPEED CONTROL
setting as desired. Remember - BLADE CONTROL

FIG. -MOWING CONTROLS
NOTE: When mowing down-hill, use a ”low” setting
on the GROUND SPEED CONTROL lever, and brake
:by engaging and disengaging the WHEEL DRIVE
CONTROL (CLUTCH).
MOWING / VACUUMING HINT: THE MOWING DECK
SHOULD BE LEVEL UNDER ALL CONDITIONS.
NOTE: Following the use of a dry-type fertilizer, itis
recommended that the lawn be sprinkled BEFORE
using the mower - to avoid vacuuming up the fer-
tilizer.
Changing your mowing pattern from time to time
creates a smoother cut lawn. Finely chopped clipp-
ings add nutrients to the soil-promoting grass
growth! However, if accumulation becomes too
heavy, matting can develop and "thatch” forms and
prevents breathing, holds excessive moisture, and
can destroy root structure! The SNAPPER That-
cherizer Kit #6-0476 can prevent the development of
thatch. Dislodged thatch can be vacuumed with your
mower if it is equipped with the grass bag. If your
SNAPPER is side discharge equipped, it can be easily
converted to a bagger and back to a side discharge
unit as often as desired! Refer to the ACCESSORIES
section for kits available for your mower!
EMPTYING GRASS BAG
When the grass bag becomes full, stop engine and
litt the BAG WIRE SUPPORT hooks (6) up over the
LOWER HANDLE (14) and then lift the BAG CON-
NECTOR (5) off the adaptor flange and continue
lifting while moving the bag forward until it clears
the mower. To empty the bag, raise the connector
end up and release the handle of the door flap.
Shake the bag back and forth to dump the clippings.
Refer to FIG. 7.
To re-install the bag, slide the BAG CONNECTOR
down over the adapter flange, then lower the BAG
WIRE SUPPORT hooks onto the LOWER HANDLE.
TO EMPTY INTO TRASH BAG: After removing the
. grass bag from the mower, place CONNECTOR end
on ground, open door flap, slip a trash bag over the
end (BAG WIRE SUPPORT end), and then turn the
mower bag over so that the large opening is inside.
trash bag. Lift bag- by the CONNECTOR and door
handles and shake until clippings are dumped into
the trash bag. |
FIG. 7-EMPTYING GRASS BAG
SERVICE PROCEDURE
Your SNAPPER mower requires very little service,
however, it is important that the engine be serviced
at the intervals specified in the engine manual fur-
nished with your mower.
To retain the integrity of your mower, only use Ge-
nuine SNAPPER Replacement Parts.
— By returning your mower to an Authorized SNAPPER
Dealer on a yearly basis for inspection and addition
of any new devices to upgrade your mower, the
reliability of the unit's functions will be assured.
Check the yellow pages under LAWN MOWERS for
the nearest SNAPPER Dealer. Always mention the
model and serial number of your mower when con-
tacting the dealer for information, parts, or service.
WARNING: Always disconnect the spark plug wire
from the spark plug when inspecting/servicing the
mower - to prevent unintentional engine start-ups.
NOTE: When tipping the mower to work on the
underside, always tilt the mower with the spark plug
UP to prevent flooding the engine with gasoline
and/or oil which would cause hard starting after ser-
vicing.
For engine parts/service, check the yellow pages
under the heading ENGINES - gasoline, for the
nearest engine manufacturer's dealer.
LUBRICATION SCHEDULE
*ENGINE: Change oil every 25 hours as specified in
engine manual; check oil level before each use.
* TRANSMISSION: (on the self-propelled models):
The transmission is filled with 4 ounces of SNAPPER
"00" grease at the factory and under normal usage, will
not require additional grease. It is recommended that
plug (A) be removed after every 25 hours of operation,
and a visual determination of the lubrication condition of
the transmission be made. If grease IS NOT visible on
the INPUT GEAR (the small gear below the plug
opening), add a small amount of SNAPPER "00" grease.
Reinstall the plug (A) after servicing the transmission.
Refer to FIG. 8.

DRIVEN DISC SERVICE
If the mower does not pull properly, refer to FIG. 12,
and check for the following:
OO Grease on drive disc (C)-causing slippage.
[0 Broken or disconnected DRIVE SPRING (D)
(also refer to FIG. 14).
О) Driven disc rubber ring (8-1) worn - not con-
tacting drive disc (C) properly.
J Driven disc (B) out of adjustment
O Worn belts
DRIVEN DISC ADJUSTMENT
The driven disc should be properly adjusted for optimum
operation, minimum rubber ring wear, smooth shifting,
and to prevent the mower from jumping out of gear due
to misadjustment. If the clutch is properly adjusted, and
both belts are in good condition (or are new), check the
two adjustments and correct if necessary.
Check the "DISTANCE" from the CENTER of the driven
disc's rubber ring to the left EDGE of the drive disc.
1. Shift the GROUND SPEED CONTROL into the
highest setting, and STOP engine. The CENTER of
the rubber ring should be 1/8" to 1/4" from the left
EDGE of drive disc as shown. To re-adjust, loosen
connector hex nut (A-1) then slide the driven disc
LEFT or RIGHT (on hex shaft) as required. Re-
tighten connector hex nut. |
Check the "TRACKING POINT". The rubber ring should
contact the drive disc's surface at a point 1/8" in front of
an imaginary reference centerline crossing through the
center of the drive disc. You may wish to draw the
centerline with a pencil.
When properly adjusted, the rubber ring will "Track"
(run) in place approximately half way between the
center ‘of the drive disc and it's left EDGE, with the
transfer rod (F) disconnected and the engine running.
Perform this test before making adjustment number 2.
DRIVEN DISC REPLACEMENT: If the driven disc rub-
ber ring (B-1) is found to be badly chunked or worn
down to within 1/16” of the metal rim of the driven
disc hub (B), it must be replaced. Remove the clip (E)
at end of speed control rod, and then turn the
transfer rod (F) to a upright (vertical) position and
detach from the connector (A) (FIG. 14 & 15). Unhook
drive spring (D) (use needle nose pliers) and slide the
driven disc assembly off hex-shaft. |
Remove the five machine screws (G) and plate secur-
ing the driven disc rubber ring (B-1) to the hub
(3) and replace the ring as shown in FIG. 15. Reverse
procedures for re-assembly and installation.

BELT SERVICE
Slippage (from worn -belts) can prevent self-
propelled models from maintaining optimum perfor-
mance! On self-propelled models, the engine belt
transmits power to the Poly-V-Belt, which in turn,
.engages the clutch to drive the transmission and
rear drive wheels.
ENGINE BELT REPLACEMENT: Disconnect the
spark plug wire and empty the fuel tank (or tape the
vents in the filler cap closed to prevent fuel spillage).
Unhook the idler arm spring (A) from the right rear
wheel bracket and remove the driven disc assembly as
described in the DRIVEN DISC SECTION. Tilt the
mower up on its LEFT wheels and remove the cutting
blade and hub. Then, while holding the slotted end of
the drive disc with a screwdriver, remove the drive disc
retaining nut (B) and internal tooth lockwasher (C). Lift
the drive disc up from its position on the idler arm and
remove worn belt. Loop one end of replacement belt
over engine drive pulley and insert other end through
deck opening. Loop the belt around driven pulley (on
the lower portion of drive disc) and lower disc back into
position on idler arm. Make sure to reassemble
components as shown in FIG. 17.
~ Reinstall the internal tooth lock washer (C) and re-
taining nut (B) onto drive disc post (on underside of
deck), and securely tighten. Test the pivoting action
of the idler arm - it must pivot freely! Reinstall the
blade and fasteners on shaft as explained in the
BLADE SERVICE section. Use a stiff wire (such as a
coat hanger) with a hook on end to pull the hooked
end of idler arm spring (A) through the large hole in
right wheel bracket, and then hook the spring's end
through the smaller hole. If the Poly-V-Belt is NOT
going to be replaced, reinstall the driven disc
assembly.

- STORAGE PROCEDURE
Refer to the engine manual for directions regarding
engine storage preparations.
Prepare the mower for "end of season” storage as
follows:
1. DISCONNECT THE SPARK PLUG WIRE
BEFORE ANY OTHER PREPARATIONS ARE \®
MADE! |
2. Tape all openings closed to prevent spraying
water into exhaust or air intakes during -
washing. |
3. Turn the mower on its side and thoroughly
clean the underside of the deck. Scrape away
any accumulation of grass with a putty knife
and/or wire brush. Then use a hose to wash
down the underside of deck and allow to dry.
Clean all external surfaces of mower and
allow to dry.
4. Lubricate all exposed metal with a light
coating of oil to prevent corrosion.
5. If so equipped, empty the grass bag to pre-
vent decay of debris and formation of mold
while in storage. The grass bag may be wash-
ed in detergent, but allow it to dry thoroughly!
6. Store the mower in a shed or other dry area,
protected from weather.
7. Handles on push models may be tilted for-
ward AFTER loosening both LOWER KNOBS
20. Grass bags and adaptors DO NOT need to
be removed.
To tilt handles on self-propelled models,
disconnect the transfer rod clip (on end of | | FIG. 19
transfer rod and speed control lever) and |
follow the procedures above. HANDLE STORAGE
Carefully tilt the handles forward, "flexing”
the control cables to prevent "kinks"

2 YEAR LIMITED WARRANTY
For two (2) years from purchase date for the original purchaser's residential, non-commercial use, SNAPPER,
through any SNAPPER dealer will replace, free of charge, any part or parts found upon examination by the factory
at McDonough, Georgia, to be defective in material or workmanship or both.
For ninety (90) days from purchase date for the original purchaser's commercial, rental, or other non-residential
use, SNAPPER, through any SNAPPER dealer will replace, free of charge, any part or parts found upon
examination by the factory at McDonough, Georgia, to be defective in material or workmanship or both.
All transportation costs incurred by the purchaser in submitting material to a SNAPPER dealer for replacement
under this warranty must be paid by the purchaser.
This warranty does not apply to engines and their components, or, Peerlesse Transaxles, as these items are
warranted separately by their manufacturers. This warranty does not apply to parts that have been damaged by
accident, alteration, abuse, improper lubrication, normal wear, or other cause beyond our control.
There is no other express warranty.
Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to two (2)
years from purchase date for the original purchaser's residential, non-commercial use [ninety (90) days from
purchase for the original purchaser's commercial, rental or other non-residential use], and to the extent permitted
by law, any and all implied warranties are excluded. This is the exclusive remedy. Liabilities for consequential
damages, under any and all warranties are excluded.
Some states do not allow limitations on how long an implied warranty lasts, or do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
WARNING: THE USE OF REPLACEMENT PARTS OTHER THAN GENUINE SNAPPER PARTS MAY IMPAIR
THE SAFETY OF SNAPPER PRODUCTS AND WILL VOID ANY LIABILITY AND WARRANTY BY
SNAPPER ASSOCIATED WITH THE USE OF SUCH PARTS.
