•Engine/PTORpm
•3PointHitch(Raise/Lower)
•AuxiliaryValveOperation
•Clutch
•Throttle
•GearSelection
•Parkingbrake

TractorPTOSpeed
TheaeratorisdesignedtooperatewithaPTOspeed
ofupto500rpmdependingonthesize/weightofthe
tines.Mosttractorsindicatea540PTOrpmposition
ontherevcounters.SincetheengineandPTOrpms
aredirectlyproportional,youcandeterminetheengine
rpmrequiredfora400rpmPTObycalculatingas
follows:
(Enginerpmat540PTOspeed)x(400÷540)=requiredengine
rpm
Forexample,iftheenginerpmwere2700foraPTO
speedof540rpm,youwouldget:
2700x(400÷540)=2000rpm
