TractionUnitPTOSpeed
TheaeratorisdesignedtooperatewithaPTOspeed
ofupto460rpmdependingonthesize/weightof
thetines.Mosttractionunitsindicatea540PTO
rpmpositionontherevcounters.Sincetheengine
andPTOspeedsaredirectlyproportional,youcan
determinetheenginespeedrequiredfora400rpm
PTObycalculatingasfollows:
(Enginerpmat540PTOspeed)x(400÷540)=requiredengine

Forexample,iftheenginerpmwere2,700foraPTO
speedof540rpm,youwouldgetthefollowing:
2,700x(400÷540)=2,000rpm
