•Removealldebrisorotherobjectsthatmight interferewithoperation.Keepallbystandersaway fromtheworkarea.

•Locateandmarkallundergroundobstructionssuch asirrigationcomponents,electricalortelephone lines.

•Makesuretractorisinneutralandparkingbrake appliedbeforestarting.RefertoTractorOperator's Manualforsafestartingprocedures.

•Ensurethatyourtractorissuitableforusewithan implementofthisweightbycheckingwithyour tractorsupplierormanufacturer.

•Mountingtheaeratortotherearofthetractorwill decreasetheweightonthetractorfrontaxle.To assureadequatesteeringcontrolandstabilityitmay benecessarytoaddballasttothefrontofthetractor. RefertoTractorOperator'sManualforballast requirements.

Transporting

•Theaeratorisheavy.Whenattachedtoatractor andintheraisedposition,itsweightwillaffect stability,brakingandsteering.Exercisecautionwhen transportingbetweenworkingareas.

•Alwaysmaintainpropertractortirepressure.

•Besureyouareincompliancewithallregulations beforetransportingequipmentonthepublicroads andhighways.Makesureallrequiredreectors andlightsareinplaceandarecleanandvisibleby overtakingandoncomingtrafc.

•Neverallowpassengerstorideonthemachine duringtransport.

Itisnecessarytofamiliarizeyourselfwiththeoperation ofthefollowingtractorcontrolsbeforeyouareableto operatetheaerator:

•PTOEngagement

•Engine/PTORpm

•3PointHitch(Raise/Lower)

•AuxiliaryValveOperation

•Clutch

•Throttle

PrinciplesofOperation

Thetractor'sthreepointhitchlinkage/hydraulictop linkliftstheaeratorfortransportandlowersitfor operation.

Thetractor'spowertakeoff(PTO)poweristransmitted viashafts,gearboxandO-ringdrivechainstoa crankshaftwhichdrivesthetineholdingarmsintothe turfsurface.

AsthetractortravelsforwardwiththePTOengaged andthemachinelowered,aseriesofholesarecreated intheturfsurface.

Thedepthofthetine'spenetrationisdeterminedby extendingthehydraulictoplinkorsettingthexedtop linktothedesiredposition.

Note:Donotattempttoadjustaxedtoplinkwhile themachineisrunning.

Thedistancebetweentheholescreatedisdetermined bythetractor'sgearratio(orhydrostatictractionpedal position)andthenumberoftinesineachtinehead. Simplychangingenginerpmdoesnotchangehole spacing.

Forexample,iftheenginerpmwere2700foraPTO speedof540rpm,youwouldget:

2700x(400÷540)=2000rpm

Inthisexample,runningyourtractorat2000rpmnow providesyouwitha400rpmPTOspeed.
