We installed an Agleader pf3000 pro with GPS on our R-50 gleaner. Did all the work ourselves, all in all I would guestimate it took 2 guys 2days to install it .Instructions were very good, took longer to figure out where we wanted to route cables etc then it did to actaully do the work. Its a fairly straight forward install . Cost was around $12,000 Can .( approx $8000 uS)
