OBSERVETRACTORLIMITS
Observingthelimitsofthetractorandmowerwill
helpitserveyoulonger.Overloadandmistreatment
canshortenitslifeorimpairitsusefulness,justas
theycanwithanytoolormachine.
1.Theengineisnotguaranteedonaslopeofmore
7

than45degrees in anydirection, asit cannotreceive
properlubrication.
2. Keep the mowerclean,especiallyaround the
blades. A build-up of grassclippings inthe blade
housing can impair the efficiency ofthe mower and
causeunevencutting.
3. Itis possible,whenusingyourrotarymower
attachmentonthetractor, to develop an irregularcut-
tingpattern if youoperate the tractorusingtoofast a
forwardspeed.Also,unevenness of cut,skipping or
steppedeffect on turns, or streaks or uncutportions
ofgrassinthemiddlemay be noticed if toofast a for-
wardspeedisused.Thatiswhyyourtractor is equip-
pedwith a three or fourspeedtransmission, so that
youwillhave a selection of forwardspeeds to choose
from,depending on yourspecificgrasscuttingjob.
Bestresults are alwaysobtained in first(slowest)
speed.
4. The dischargeopening ofthe mowerattach-
menthasbeenconstructed to allow for maximumdis-
charge of grasscuttingsundernormaloperatingcon-
Aprotectiveshrub barhas beenprovidedacross the
dischargeopening;DoNot,under any circumstances,
impairthesafeoperation of yourtractor by removing
it.
5. Avoidpullingloadsthataresoheavytheycause
thedrivebelt to slip or wheels to spin.
6. If tractorstalls duetoan overload, butthe
enginecontinues to run,shiftimmediately to neutral
andstart out againslowly.Failure todo thiswill
causeexcessivebeltwear or breakage.
7. Iftheenginestallsdue to overload,disengage
thebladeclutch and shiftintoneutralbeforerestart-
ing.Then,findoutwhatcausedtheoverload and avoid
it to make it easierwhenstarting out again.
8.Whenusingany ofthe groundengagingattach-
mentsalways use either the firstforwardspeed or
2nd, not3rdor4th; theseattachments are developed
to usethe maximumpowerdelivered by yourtractor
andthis can only be obtained in first or secondfor-
wardspeed and maximumengineRPM.
