1.EngagePTOatlowenginespeed.Increaseengine
speedtoachievePTOspeedof540rpm(maximum)
andtheloweraerator.Operateatanenginerpm
thattheaeratorrunsmostsmoothly.
Note:Changingengine/PTOrpminaparticular
tractorgear(orxedhydrostaticpedalposition
ontractorswithhydrostatictransmission)willnot
changeholespacing.
2.Makeverygradualturnswhenaerating.Nevermake
sharpturnswithPTOdriveengaged.Planyour
aerationpathbeforeloweringtheaerator.
3.Iftractor“bogs”downwhenoperatingonhard
groundorgoinguphill,raiseaeratorslightlyuntil

5.Raiseaeratorpenetration,ifgroundishardpacked.
Cleanupcoresandre-aerateatdeeperpenetration,
preferablyafterwatering.
6.TheProCore864aeratorisoffsettothetractor’s

7.Alwayscheck/adjusttoplinkwheneveraeration

bevertical.
Toavoidpersonalinjury,neverleavethetractor
