3. Check discharge chute for proper rotation.
4. Check operation of tilt control for upper chute.
5. Verify that the lift handle will lock into and release from
the raised transport position. (Refer to the Service and

OPERATION
KNOW YOUR SNOW THROWER
Read this owner's manual and safety rules before operating your snow thrower.
Comparetheillustrationbelowwithyoursnowthrowertofamiliarizeyourselfwiththevariouscontrolsandtheirlocations.
CHUTE TILT HANDLE Pivots the Upper Chute up or
down to control the angle and distance of discharge.

HOW TO START YOUR SNOW THROWER
• Thetractorshouldbesittingwiththeenginerunning
at full throttle. Move the attachment clutch to the
engagedposition,startingthesnowthrowerbefore
the tractor clutch is engaged.
HOW TO STOP YOUR SNOW THROWER
• Tostopthesnowthrower,disengagethetractor's

owner'smanual.
CAUTION: Never direct discharge

allow anyone in front of unit.
CONTROLLING SNOW DISCHARGE
• Tocontrolthedirectionsnowisthrown,thedischarge
chute has 180 degrees of rotation. Turn the crank rod
clockwise to rotate the chute to the left. Turn the crank
rod counterclockwise to rotate the chute to the right.
• Tocontrolthedistancesnowisthrown,theupper
section of the discharge chute pivots up and down.
Push forward on the chute tilt handle to pivot the chute
down, decreasing the distance snow is thrown. Pull

REMOVING SNOW
Snow removal conditions vary greatly from light uffy
snowfall to wet heavy snow. Operating instructions must
beexibletottheconditionsencountered.Theoperator
must adapt the lawn tractor and snow thrower to depth of
snow, wind direction, temperature and surface conditions.
• Beforebeginningoperation,thoroughlyinspectthe
area of operation and remove all door mats, sleds,
boards,wiresandotherforeignobjects.
• Thespiralaugerspeedisdirectlyrelatedtoengine
speed. For maximum snow removal and discharge,
maintainhighenginer.p.m.(fullthrottle).Itisadvisable
to operate the lawn tractor at a slow ground speed
(1st gear) for safe and efficient snow removal.
• Indeep,driftedorbankedsnowitwillbenecessaryto
use full throttle and a slow ground speed (1st gear).
Driveforwardintothesnow,depressthetractor's
clutch-brakepedalandallowthespiralaugertoclear
the snow. Repeat this method until a path is cleared.
On the second pass, overlap the rst enough to allow
the snow thrower to handle the snow without repeated
stopping and starting of forward motion.
• Inextremelydeepsnow,raisethesnowthrowerfrom
the ground to remove the top layer and drive forward
only until the tractors front tires reach the uncleared
bottomlayerofsnow.Depressthetractor'sclutch-
brakepedalandallowthespiralaugertoclearthe
snow. Reverse the tractor and lower the snow thrower
to the ground. Drive the tractor forward until the snow
againbecomestoodeep.Repeatingthisprocessinto
and out of drifts will eventually clear even the deepest
of snow piles.
• Ifthesnowthrowerbecomescloggedwithsnowor
jammedwithaforeignobject,disengagethesnow
thrower immediately and shut off the tractor engine.
Unclogthesnowthrowerbeforeresumingoperation.
OPERATING TIPS
• Dischargesnowdownwindwheneverpossible.
• Tohelppreventsnowfromstickingtothesnowthrower,
allow the snow thrower to reach outdoor temperature
beforeusingit.Alightcoatofwaxmayalsobeapplied
to the inside surface of the snow thrower housing and
discharge chute.
• Usetirechainstoimprovetraction.
• Userearwheelweightstoimprovetraction.
• Beforetherstsnowfall,removeallstones,sticksand
otherobjectswhichcouldbecomehiddenbythesnow.
Permanentobstaclesshouldbemarkedforvisibility.
• Overlap each pass slightly to assure complete snow
removal.

(Refer to gure 58 on page 24.)
• Raisethesnowthrowertothehighestposition.
• Checktheclearancebetweentherearoftheidler
