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
be cut from the grass. |
EXAMPLE: If the grass is 4” tall, set the four AD-
JUSTING LATCHES (1) in notch 5 (the highest
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 then the
necessary development and reinforcement of a good
healthy root system!

WARNING: DO NOT operate mower without the

always Install the proper side discharge chute or
bag adapter and grass bag. The special blade provid-
replaced for side discharging or bagging grass.
If allowed to grow too tail, 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. :
NOTE: Following the use of a dry-type fertilizer, it is
recommended that the lawn be sprinkled BEFORE
using the mower - to avoid vacuuming up the fer-
tilizer. |
MOWING/VACUUMING HINT: The mowing deck
should be level when bagging.
— 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 s 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! |

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.C4
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
transfer rod and speed control lever) and
follow the procedures above.
Carefully tilt the handles forward, "flexing”
the control cables to prevent "kinks"
