See Figure14. f Battery Failures Somecommoncausesfor batteryfailureare: • Incorrectinitialactivation• undercharging • Overcharging• corrodedconnections • Freezing Thesefailuresare NOTcoveredby yourtractor'swarranty. CHECKING MAIN HARNESS FUSE • A 20 ampfuse is installedin yourtractor'swiringharnessto protectthe tractor'selectricalsystemfrom damagecausedby excessiveamperage. • If theelectricalsystemdoesnot function,or yourtractor'sengine will notcrank,first checkto be certain that thefuse hasnot blown. • Thefuse can be foundinsideof the dashpanel behindthe battery tray.You may needto removethe batteryto gain accessto the fuse.Alwaysusea fuse with the sameamperagecapacityfor replacement. NOTE:A secondfuse holder canbe foundinsidethedash panel.This fuse holderisusedfor the optional12volt poweroutlet. ADJUSTMENTS Neverattemptto makeanyadjustmentswhilethe engineis running, exceptwherespecifiedin theoperator'smanual.Disconnectspark plugwire(s) beforeperforminganyadjustments,repairsor maintenance. Steering and Transmission Linkage Thesteeringtie rod and drag links and the relatedtransmissionlinkage are set at the factoryand shouldnot requirefurtheradjustment. Becauseof the complexadjustmentprocedure,the steeringand transmissionlinkageshouldonlybe servicedor adjustedby a qualified mechanic.If youexperienceproblemswith steering,or with the IVT transmission,contactyournearestSearsParts& RepairService Centerto havethetractorinspected.

Oncethe desiredpositionis reached,releasetheseat lever.Slide the seat slightlybackand forth as necessaryto engagetheseat leverinto one of theeight adjustmentpositionsin the indexplate. Makecertainthe seat is lockedin position. Side to Side Leveling the Deck NOTE:Checkthe tractor'stire pressurebeforeperforminganydeck levelingadjustments.Referto "Tires"earlier in this sectionfor information regardingtire pressure. If the cuttingdeck appearsto be mowingunevenly,a sideto side adjustmentcan be performed.Adjust if necessaryas follows: 1. With the tractorparkedon a firm, levelsurface,movethe deck to the mid heightposition(thirdor fourth notch)usingthe deck lift lever.Rotatethe left bladeso that it is perpendicularto the tractor frame.Measureand recordthe distancefrom the outsideof the left bladetip to the ground. 2. Movingto the otherside of thetractor,rotatethe right bladeso that it is perpendiculartothe tractorframe,and measurethe distancefrom its outerbladetip to theground. 3. Bothmeasurementstaken shouldbe approximatelyequal. If they'renot, notewhetherthe left side of the deck is loweror higherand proceedto the next step. 23
