possible) you can prevent this.
When using side discharge, turn clockwise (right turn)

when beginning to mow large open areas. This
discharges clippings away from borderline objects
(sidewalks, driveways, fences, etc.). After making a
clockwise pass, mow in a counterclockwise (left turn)
direction. This discharges clippings evenly over cut
grass. Continuous clockwise mowing will cause a build
up of clippings, preventing a uniform cut. Also, plan
cutting so that you always trim with the ieft side of
mower when using side discharge.

Restarting engine will be easier if mower is allowed to
completely discharge clippings before stopping engine.

On electric start model, if starter will not cycle because

of grass buildup under deck, rotate blade with rewind
starter to clear blockage.

Be sure your mower blade is sharp. A dull blade will tear
grass blades. This usually results in a white cast over a
freshly cut lawn. Later, tips of grass blades will turn
brown.

A new lawn has much softer blades of grass and has a
higher moisture content. It is important for this type of
lawn to be cut with sharp blades.

Cutting height will vary with different types of grass,
climate and individual preference. Generally, grass
should be cut about 1-1/2” long in spring, and not less
than 2” long in hot summer weather.

If grass is high, or if it contains a high degree of
moisture, cut it first with mower set high and then cut it
with mower set lower. This gives better distribution or
collection of clippings and provides a clean second cut.

A good fertilization program and frequent watering will
keep your lawn weed free and green all year long. Due
to variations in climate, soil and grass varieties, contact
your local garden supply dealer, park or golf course
superintendent, or county agent to obtain specific

information pertaining to your area.

NOTE: Be sure to empty grass bag and clean mower

pan after each use. A dirty unit may not bag and/or cut

grass properly.

Do not allow grass clumps or a coating of grass and
debris to collect inside of grass bag or mower pan.

Avoid operating over bare ground intermittent with grass

cuttings as this causes dirt and grass to collect and cake
under pan surface as well as in grass bag. To tip mower
for cleaning under side of pan refer to Lubrication and
Maintenance section of this manual.

Grass bag should be washed with hose and allowed to
dry. Washing grass bag prevents debris buildup, that

will clog mesh of bag, which will prevent proper air

circulation and bagging of grass.

Mulching Tips

Height of cut should not be set too low on thick, lush
lawns. Such grass, if cut too short, may die. This also
applies to springy, heavy growth lawns. If blade is set
too low, mower pan will drag on grass and restrict air
flow thus reducing discharge or collection of clippings.

Grass should be cut when it is dry; not when it is wet
from dew, rain or from watering. When wet, grass tends
to pack inside mower pan or chute and will not
discharge, mulch or bag properly, especially if height of
cut is set too low.
To insure most complete and even cut, overlap each
swath.

Following the same pattern each time you mow your
lawn can develop ridges at right angles to direction of

For best performance, it is recommended that the height
of cut for your mower be set at, or as near as possible
to, 3 inches and that not more than 1 inch of grass is

removed per cutting. This can be controlled easier by
obsen/ing the “Mulching Zone Decal” (Part No. 077123).

The decal serves as a height gage for measuring the 1

inch maximum per cutting range.

Grass should be cut when it is dry, not when it is wet
from dew, rain, or from watering. When wet, the grass
will tend to ball and pack inside the mower pan and will

not disperse evenly. If the grass does not disperse

evenly, it is probably because too much grass is being

removed per cutting, the grass is too wet, or the travel
speed is too fast.

parts which are hot from operation.

Allow such parts to cool before

servicing

General

Mower does not require any lubrication. Wheel
assemblies are .designed for long life without
additional lubricatiori. (The professional models
911065 and 911317 has zerk fittings on drive carrier
and rear axle).

Service Positions

Pi

Figure 6: Handlebar Service Position

NOTE: On the models with Kawasaki engines,

remove the side discharge deflector, if so equipped,

prior to tipping the machine.

NOTE: A piece of plastic bag may be used to seal

fuel tank opening when tipping mower. To seal,

remove fuel tank cap, cover fuel tank opening with
plastic, replace and tighten cap securely before

tipping mower. Be sure to remove plastic before

attempting to operate mower.

A handlebar service position is provided, for tipping
the unit, for convenient cleaning and service
operations.

To place handlebar into the handlebar service
position, remove braces from pins, rotate handlebar
forward and place pins into holes of braces. See

Figures 6 and 13.

NOTE: Nuts and bolts replace pins on Professional

Models.

IMPORTANT: When tipping to service engine or unit,

use the following service positions for the brand and

type of engine on your mower:

Tecumseh Vector and Centura Engines; place

handlebar into handlebar service position and tip
machine to the rear.

Briggs & Stratton Quantum and Diamond Plus

Engines; place handlebar into handlebar service

position and tip the machine to the left, opposite the
side descharge deflector.

Kawasaki Engines; place handlebar into handlebar

service position and tip machine to the right, side

discharge deflector side.

WARNING: Gasoline is highly flammable

A

IMPORTANT: If 4 cycle engine becomes “flooded”

due to tipping, clean air cleaner. Gasoline, drawn into
cylinder may wash cylinder wall and shorten engine

life. If cylinder wall becomes washed with gasoline,

remove spark plug, put one teaspoon of oil in
cylinder, turn engine over a few times and replace
spark plug.

and must be handled with care.

Engine Oil (4 cycle engines)

Use a high quality detergent oil classified “For API

Service SF or SG” with a single viscosity SAE30.

Capacity is approximately 1-1/4 pints. Detergent oils

keep engine cleaner and retard formation of gum and

varnish deposits. DO NOT add anything to

recommended oil.

Checking

The engine crankcase oil should be checked daily or
every five (5) hours of operation.

To check oil, place mower on flat, level surface. Wipe
all debris from around oil fill cap.

12

Lubrication and Maintenance (Continued)

To check oil, place mower on flat, level surface. Wipe
all debris from around oil fill cap.

Turn cap, remove dipstick from engine and wipe oil
off dipstick. Insert dipstick into fill hole and turn slowly

until cap bottoms firmly. Remove dipstick and
observe oil level. If low, add fresh clean oil (of same
type and viscosity as is in engine) to bring oil level to
full (F) mark. Replace dipstick being sure to tighten
cap firmly.

IMPORTANT: DO NOT over fill. Level must not

exceed full (F) mark. Oil level MUST be maintained in

safe operating range on dipstick at all times or engine

damage will result.

Changing Oil

IMPORTANT: Change engine crankcase oil after

first two (2) hours of operation, thereafter, change oil

every twenty fiye hours of operation (more often in

dusty dirty conditions).

NOTE: Run engine just prior to changing oil. Oil will

flow more freely and carry away more contaminant’s

when warm.

Place mower into the Service Position specified for

your brand and type of engine. (See Service

Positions section). Professional models 911065 and
911317 remain in the operator’s position. Attach oil
drain hose to end of engine oil drain. Place a
suitable container under oil fill, remove oil fill cap with
dipstick and allow oil to drain into container.

Place machine back onto wheels, add fresh clean oil
to proper level and be sure to replace oil fill cap with
dipstick.

Lubrication and Maintenance (Continued)

Inspect air cleaner every 10 hours of operation or
every month, whichever occurs first.

When dirty, filter elements should be removed and
cleaned per the following instructions.

NOTE: Inspect air cleaner more often if unit is used

under dirty dusty conditions.

A

CAUTION: Periodically clean muffler
and manifold areas to remove all grass,
dirt and combustible debris. If engine
muffler is equipped with spark arrester
screen assembly, remove every 50
hours for cleaning and inspection.
Replace if damaged.

To inspect and/or clean remove cover and filter
element(s) and/or cartridge from air cleaner body.

NOTE: Clean air cleaner cover and body before

installing clean or new components.

Foam Filter Element (Pre-cleaner) - Wash foam

elements in warm water with detergent. Rinse
thoroughly until all traces of detergent are eliminated,
squeeze (don’t wring) away excess water and air dry.

Soak foam element in clean fresh oil, wrap in paper
towel or rag and squeeze out excess oil.

Cartrldge/Or Paper Filter Element - Clean by

tapping gently on flat surface. Replace if it is very
dirty or becomes distorted.

Engine Cooling

The engine is air cooled. Air must circulate freely
around engine and over cooling fins on cylinder head

and block to prevent overheating.

Once a year or every one hundred (100) operating
hours (more often if conditions require) clean engine

fins and external surfaces of engine of dust, dirt, and

oil deposits which can contribute to improper cooling.

IMPORTANT: DO NOT operate engine with blower

housing removed - this will cause overheating and
engine damage.

Spark Plug

Spark plug should be cleaned or replaced (if
necessary) and gap reset to .030” every 100 hours of
operation or yearly whichever comes first.

To clean, remove debris from area around spark plug
base, remove spark plug from engine, scrape and
wash with a commercial solvent. DO NOT blast
clean.

NOTE: Sparking can occur if wire terminal does not

fit firmly on spark plug. Reform terminal if necessary.

Muffler

Worn out mufflers are more than just a noise

nuisance and should be replaced immediately.
Continued use could result in fire or explosion.
