TIPS ON MOWING
FOR BEST RESULTS,
WHEN MOWING:

USE THE FOLLOWING

TIPS
CHUTE DEFLECTOR
(42" Cutting Deck)

When mowing, cut only 113 off of grass height.
Cutting grass deeper could be harmful to your
lawn.

FIGURE 13

If cutting extremely tall grass, make one cutting
with the deck in its highest cutting position, then
lower the deck to desired position and make a
second cut.

WARNING

Mow when lawn is dry for best cutting.
Mow often. Shorter grass clippings
more quickly.

Never attempt to operate mower without chute I
deflector secured in the down position!
I

decompose

Keep mower blades sharp. A dull blade tears and
shreds grass instead of cutting. Refer to "MOWER
BLADE SERVICE" in the Maintenance Section.

Alternate the mowing pattern every other time to
reduce the possibility of grass matting.
Mow with engine speed control in FAST and
ground speed control handle in a SLOW position.
Clean deck, removing all grass clippings and debris
from the top and underside of deck after each use.

When using the Trouble-Shooting Guides on this page and the next, don't overlook the simplest cause
first, even though it may seem too obvious to consider. For example, if the engine will not start, it simply
may be out of fuel. The Guides generally list the most simple causes first in each problem category to
help you locate the cause through the process of elimination.

BATTERY CHARGING PROCEDURE
The engine is equipped with a flywheel altemator to
charge battery. If the tractor is not run regularly,
connect battery to a charger monthly to maintain
charge. If low, battery liquid could freeze at zero
degree temperatures causing cracking of the battery
case. To prevent freezing, keep the charge up or
remove the battery from the tractor and store battery in
warm, well ventilated area during the off season. Store
on wooden surface, not on cement floor.

CHECKING

Always remove the Negative (.) cable first to
prevent arching and remove Positive (+) cable last.

To charge, connect a constant current charger
(not trickle type) and follow instructions furnished
with the charger.

If time allows, slow charge at 1 amp for 10 hours, or
as an alternate, fast charge at not more than 2.5
amps for four hours. Observe ALL Precautions
while charging.

Install Positive (+) cable first and install Negative(-)
cable last. Apply a small amount of grease over the
terminals to prevent corrosion.

BATTERY ELECTROLYTE

WARNING
The Electrolyte (Acid) produces a highly explosive
gas. Keep all Sparks, Flame and Fire away from the
area when charging battery or when handling
electrolyte or battery. Electrolyte (Acid) is a highly
corrosive liquid. Wear eye protection. In case of
eye or skin contact with Electrolyte (Acid), wash
all affective areas of the body immediately with
water.

Clean top of battery, disconnect battery positive cable
to prevent arching, then carefully remove the battery
cell covers.

Re-install seat assembly over battery and secure in
position with adjusting knobs. Leave knobs loose
until the seat is adjusted, then tighten.

ACTIVATING A NEW BATTERY
Activating a new Battery with Electrolyte (Acid) will
bring it up to 80 % of full charge state. It must be
brought up to full charge, which means 20% additional
charge is needed. Charge a new Battery for 2 hours on
a slow charge rate of I Amp to bring it up to full charge
before installing it in tractor.

Visually check electrolyte level in each cell. Level
should be 3116" above cell plates up to the fill rings.
Using distilled water, fill cells as needed to bring level
up to, but not over, the fill rings. See Figure 29.
Replace cell covers and reconnect the positive cable if
disconnected earlier.

by applying pressure on the Idler Assembly and then
sliding the Belt off of the center Pulley/Spindle
Assembly. See Illustration.

STEP 2. The Spindle Pulley Belt Guards must be
removed completely by removing Locknuts of which
secure Belt Guards to Deck.
STEP 3. The Idler Arm Tension Spring has to be
detached from the Spacer by removing the Nut and
Washer and sliding the Spring up and OFF of the
Spacer. This releases the tension on the Idler Arm for
easy removal of Deck Belt. Check Illustration for
verification of Belt Part Numbers.

pressure. Add or release air as needed to bring pressure
to 10 PSI in front and 10 PSI in rear tires. If tires are
property inflated and mowing ts still uneven, adjust sideto-side deck levelness first as follows:
1. Place machine on a smooth level surface.
2. Rotate outside blades so tips are pointed to the
sides of deck. See Figure 51. Measure the
distance from blade tips to floor. If the
measurement is within 1/8" from side-to-side, the
deck levelness is satisfactory. If the difference
from side-to-side is greater than 1/8", continue to

provide long, satisfactory
service. However, proper
care is essential In

manufacturers equip their
engines with extremely
efficient air cleaners to
out the harmful dirt.

gulp about 12,000
gallons of air for
every gallon of
used. Because of
Its working environ.
ment, the air available
to your Snapper engine Is "
heavily saturated with airborne dirt particles.

As the dirt particles are stopped,
they build up and begin to clog
the outside of the filter. This
reduces the amount of air
available to the engine and causes
an over-rich fuel mixture which results In the following adverse
effects:

Damage caused by a poorly serviced air
cleaner is not covered under the engine
warranties. So, save yourself unnecessary
expenses and undue aggravation by keeping
the air cleaner properly serviced at the Interval.

;

It doesn't take long to service an air cleaner.
Follow the specific instructions in the engine
owner's manual for the type filter used. Prevent dirt from falling Into the carburetor Intake
when servicing your air cleaner. Make sure
components are Installed In correct sequence
after servicing to prevent unfiltered air from
entering the engine. Some servicing hints on
several common types are:

PRIMARY MAINTENANCE
Air Is also needed to keep
your engine cool. Dirt, dust
& debris build up to restrict
and clog cooling air Intake
screens and fins. Clean
screens and fins at frequent
Intervals. The engine blower
housing and shrouds should
be removed at least once

Dirt can also be Introduced
Into an engine In dirty fuel
from a contaminated
contslner. Always use clean
fresh fuel from a clean
container to guard against
dirt, sludge and water
contsmlnatlon.

Be aware that fuel breaks
storage and forms
gummy compounds which
will block carburetor passages. Never use fuel more
than 3 months old. Drain
tank then run the engine out
of fuel before storing during
the off-season.

An engine must also have proper lubriceUon.
All englnee use some oil On 4-cycle enginee,
CHECK OIL LEVEL BEFORE EACH START-UP.
Wipe area clean around the oll check plug or
dipstick opening to keep dirt from falling Into
the engine when checking the oil Always
check with the machine on a level surface.
On engines with dipstick, keep the level up to,
but not over, the FULL mark. When adding o11,
allow time for all of the oil to flow down the fill
tube to prevent a false full reading when the
level could actually be low and result In engine
damage.

PRIMARY MAINTENANCE
On 2-cycle engines, lubrication must be
provided by an exact mixture of gasoline
and 2-cycle air-cooled engine oil. A 2-cycle
engine that Is mistakenly
run on straight
gasoline will be ruined In less than 5
minutesl
If you keep straight gasoline in
addition to pre-mixed 2-cycle engine fuel,
be sure the containers are clearly marked
to avoid mix-up.
Snapper 2-cycle engines require a 32 to 1
mixture of gasoline and BIA certified TC-W
oll such as Snapper's 2-cycle engine oil
Many of the 2-cycle engine oils on the
market today make fantastic claims, but for
the best performance and long engine life,
always use Snapper 2-cycle o11. Pre-mix
the fuel and always shake the container
before filling the tank.

On 4-cyle engines with an oil level plug,
don't be fooled into thinking the engine has
sufficient lubricating oil if you can see "some"
oil in the opening - the level should always be
brought up to the point of overflowing at the
top of the fill hole.

Change oil at regular Intervals using a a high
quality oll such as Snapper's

TIPS ON MOWING
FOR BEST RESULTS,
WHEN MOWING:

USE THE FOLLOWING

TIPS
CHUTE DEFLECTOR
(42" Cutting Deck)

When mowing, cut only 113 off of grass height.
Cutting grass deeper could be harmful to your
lawn.

FIGURE 13

If cutting extremely tall grass, make one cutting
with the deck in its highest cutting position, then
lower the deck to desired position and make a
second cut.

WARNING

Mow when lawn is dry for best cutting.
Mow often. Shorter grass clippings
more quickly.

Never attempt to operate mower without chute I
deflector secured in the down position!
I

decompose

Keep mower blades sharp. A dull blade tears and
shreds grass instead of cutting. Refer to "MOWER
BLADE SERVICE" in the Maintenance Section.
