Toro Groundsmaster 360 - Traction Circuit Component Failure

TractionCircuitComponentFailure
ThetractioncircuitoftheGroundsmaster360machinesisaclosedloopsystem
thatincludesthedualpiston(traction)pumpand4wheelmotors.Ifacomponent

Therecommendedmethodtoremovecontaminationfromthetractioncircuitis
totemporarilyinstallaTorohighowhydraulic-uidlterintothecircuit;refer
toHighFlowHydraulicFilterKit(page4–30).Useahighowhydraulic-uid
