uneasyon it, do not mow it.
DO:
• Mow up and down slopes, not across.
• Remove obstaclessuchas rocks,tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain
could overturnthe machine. Tall grass can hide
obstacles.
• Use slowspeed. Choose a low gear sothat youwill
nothave to stop or shiftwhile onthe slope.
,P Followthe manufacturer'srecommendationsfor
wheel weights or counterweightsto improve
stability.
• Keep all movement on the slopes slow and gradual.

• Do not tum on slopes unlessnecessary,and then,
turnslowlyand gradually downhill,if possible.
• DOnot mow near drop-offs,ditohes,or
embankments. The mower could suddenlyturn
over if a wheel isover the edge of a cliff or ditch,or
if an edge caves in.
• Do not mow on wet grass. Reducedtraction cot_ld
cause sliding.

CAUTION: 1
Shut off mower engine and remove spark|i
plug wire from spark plug before making 1
any adjustments to mower. J
The cuttingheight ra_e isapproximately 1-1/2 to 4-1/2
inches. The_heightsare measuredfrom thegroundto
the bladetip withtheengine notrunning. These heights
are approximateand may vary dependinguponsoil
conditions,heightof grassand types ofgrass being
mowed.
The average lawn shouldbe cutto approximately2-1/2
inchesdudngthe cool seasonandto over3 inches
duringhot months. For healthierand better looking
lawns,mow often andafter moderate growth.
For bestcuttingperformance,grass over6 inchesin
heightshouldbe mowedtwice. Make the firstcut
relatively high,the secondto desired height.
CUTTING HEIGHT ADJUSTMENTS
• To adjustthe mowercuttingheight remove hair
cotter pinfrom clevis pin inthe Height Adjustment
Strap. (See Fig. 4)
• Applydown pressureto height adjustmentliftlever.
• Remove the clevis pinfromthe heightadjustment
strap.
• Move heightadjustmentstrap up or downto alignit
withthe desired holPinthe heightadjustmentstrap.
• Reassemble clevis pintothe height adjustment
strap and secure with haircotterpin.
• Make sure that bothside heightadjustmentstraps
are adjustedto thesame height.

TOW HITCH OFFSET ADJUSTMENT
Thistow behind mower hasbeen designedto runoffset
from the center ofthe tow vehicleto give additional
cuttingwidth.
• The adjustabletow hitchofthis mower can beset in
the straight positionor to eitherside in one of three
offsetpositions, 15", 29", and 39". (See Fig. 5)
• When cuttingwith a towvehicle already equipped
witha 42", 46", or 50" mower,we recommend using
the 3g"offset, When cuttingwith a towvehicle
equippedwith 36", 38", or 40"mower, usethe 29"
offset position. When cuttingheavier grassor
when conditionswarrant, adjustthe mower tothe
15"offsetposition.
• If towvehicle isnot equippedwitha mid-mount
mower the hitchcan be adjustedto a straight
position, but we recommend usingthe offset
positionto eliminate grass being crusheddownby
thetow vehicle.
CAUTION:
Shut off mower engine and remove spark
plug wire from spark plug before making
any adjustments to mower
TO ADJUST THE OFFSET HITCH
• Pull backthe pivot latch from the notchofthe front
quadrant. Adjustthe hitchtube to the desired offset
and release the pivot latch into the notchof the
quadrant. (See Fig. 6)
• Pull backthe pivotlatch from the notchofthe rear
quadrant. Adjustthe hitchtube to the corresponding
notchof the frontquadrantand releasethe pivot
• latch intothe notch.
IMPORTANT: The hitchtube must be assembledto

BEFORE STARTING ENGINE
MOWING PROCEDURES
• Fill engine with oil (See MaintenanceSection of
this manual for properprocedureand requirements)
• Add Gasoline, Fill Fueltank usingfresh clean
unleadedgasoline.
I cAuT'°N;II,
Fill to bottom of fuel tank filler neck. Do
not overfill. Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near open flame.
CAUTION:
Tragic accidents can occur if the
operator is not alert to the presence of
children. Children are often attracted to
the machine and the mowing activity.
NEVER assume that children will remain
where you last saw them.
CAUTION:
Never carry children. They may fall off
and be seriously injured or interfere with
safe operation,
TO START ENGINE
L
CAUTION:
Keep the blade clutch lever in
"Disengaged" position when starting
engine.
• Make sure spark plugwire is properlyconnected.
• Place choke controiin "CHOKE=positionifthe
engine iscold. A warm engine may not require
chokingto start.
• Move engine throttleto full position.
• Grasp starter handle with one hand. Pull ropeout
.slowlyuntilengine reaches startof compression
cycle(ropewill pullslightlyharderat this point).
• Pull ropewith a rapia, continuous,full arm stroke.
• Keep a firm gripon starter handle and let rope
rewindslowly. Do notlet starter handlesnap back
againststarter.
• When engine starts move choketo openposition.
• Allow engineto warm up for a few minutesbefore
engagingblades.
NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32°F), the carburetorfuel mixture
may need to be adjustedfor bestperformance. See
Service and Adjustmentssectionofthe engine manual.
BREAKING IN YOUR MOWER
Break in yourbelts, pulleys and engine before you
actuallybegin mowing.
• Start engine, engage blade control to start blades
rotating and allow blades to rotate approximately
five minutes to break in mower and engine.
CAUTION:
Check area under and around mower for
ary objects that could be thrown from
under mower. Make sure'that mower
discharge area is clear.
• Mowingshouldbe started withtractorin low gear
I and speed increasedonlyas mowing conditionswill
safely permit.
• Mowerwill performat itsbestwhen enginethrottleis
set for full throttle.
You will obtainbetter mowingresults ingrassy areas
if they are mowed when the grass isapproximately
4" to 5" maximum height. While your mower will cut
grass taller than 5", you will notice e substantial
increase in engine power required and some change
in the finished appearance of the area mowed.
Mowing conditions will vary from place to place,
including the types of grass which are being mowed,
such as fine stalk, coarse stalk, dense or sparse
grasses. When mowing tall grassyou may find that
the pressure of wheel tracks may cause certain
grasses to be pushed downward so they will not be
mowed properly. If this condition exists you may
have to mow the area twice, the first mowing with
the mower raised and the second mowing at the
desired height that you have chosen. If it is
practical, you will achieve better results if the
second mowing is a right angle in travel to the
previous mowing.
Do not mow grasswhen it is wet. Wet grass will
plug mower and leave undesirable clumps. Allow
grass to dry before mowing.
Always operate mower engine at full throttle when
mowing to assure better mowing performance and
proper discharge of material. Regulate ground
speed by selecting a gear low enough to give the
best cutting performance and quality of cut.
When operating any attachmentselect a ground
speed that willsuit the terrain and give the best
performance for the attachment bein_q_us_ed:_
When mowing slopes, always mow them up and
down at slow speed. Never mow across slopes.
See Slope Operation section of Safety Rulesfor
further instruction on slope mowing.
