there is a neutral position,which islocked ifthe
steedng controls are moved outward.
When both controlsare in the neutral position
(N), the machine stands still.
By movingboth controlsan equal amount
forward or backward, the machine movesina
straight line forward or backward respectively.
In order,for example, toturndght whilemoving

position.The rotationofthe dght wheel isreduced
and themachineturnsto the dght.
Zero turncan be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position. The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the
left steering control is pulled backward, the machine
turns to the left. Use extra care when using this
maneuver

IMPORTANT INFORMATION
Experience indicates that alcohol
blended fuels (called gasohol, ethanol or
methanol) can attract moisture which
leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system of an engine
while in storage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
the next season. See Storage
Instructions for additional information.
Never use engine or carburetor cleaners
in the fuel tank or permanent damage
may occur.

Mowing Tips
Observe and flag rocks and otherfixed
objectsto avoid collisions.
Begin with a highcuttingheightand
reduce ituntilthe desired mowingresult
isattained.
The average lawn shouldbe cutto 2 1/2"
(64 mm) during thecool season and over
3" (76 mm) during the hot months.For
healthierand better lookinglawns, mow
often aftermoderate growth.
For best cuttingperformance,grass over
6" (15 cm) in heightshouldbe mowed
twice. Make the firstcut relativelyhigh;
the secondto the desired height.
The mowingresultwillbe bestwith a
high engine speed (the blades rotate
rapidly)and low speed (the rider moves
slowly). If the grass isnot too long and
dense, the ddving speed can be
increasedwithout negativelyaffecting
the mowingresult.
The finest lawnsare obtainedbymowing
often.The lawn becomesmore even and
the grass clippingsmore evenly
distributedoverthe mown area. The total
time taken isnot increased as a higher
operatingspeed can be used without
poor mowingresults.
Avoid mowingwet lawns. The mowing
resultis poorerbecause the wheels sink
intothe softlawn, clumpsbuild,and the
grass clippingsfasten underthe cowling.
Hose the mower deck undersidewith
water aftereach use. When cleaning,the
mower deckshall be raised intothe
transportposition.Make surethe mower
is cooled and the engine is off.
Use compressedair to clean top surface
of the deck. Avoid floodingwater on top
surface, engine and electdcal
components.
When the mulchingkitis used, itis
importantthat the mowing intervalis
frequent.
Mowing patterns
WARNING!
Clear the area of objects such
as rocks, toys, wire, etc.,
which could be picked up and
throw by the blades.

STORAGE
Storage
Winter Storage
At the end of the mowing season, the machine
shouldbe readied for storage (or ifit will not be in
use for longerthan 30 days). Fuelallowed to
stand for long periodsoftime (30 days or more)
can leave stickyresiduesthat can foulthe
carburetor and disruptengine function.
Fuel stabilizersare an acceptableoptionas
regards tothe stickyresiduesthat can occur
duringstorage.
Add stabilizer to the fuel inthe tank or in the
storage container.Always use the mixingratios
specifiedby the manufacturerofthe stabilizer.

very flammable and careless
use can cause serious personal
injury and property damage.
Drain the fuel into an approved
container outdoors and far
away from open flame. Never
use gasoline for cleaning. Use
a degreaser and warm water
instead.
To ready the machinefor storage,follow these
steps:
1.
Thoroughlyclean the machine, especially
under the mower deck. Touch up damage to
the paintand spray a thin layer ofoil onthe
undersideofthe mower deck toavoid
corrosion.
