You need the Case IH program to make the maps then you can save them and move them to farmworks Farmworks is more detailed farm record keeping it lets you keep seed corn, yield, chemicals, fert., etc on each farm
When your combine was delivered new, it had CIH software with it. If you're the original owner, the dealer should have supplied you with that. If not perhaps you or the dealer knows the original owner and could get the copy from that person. If he_she upgraded to a new machine with AFS they should have received a new software bundle with the new machine.
Farmworks can read data files to make the maps without the CaseIH software, but I'm not sure if Farmworks has the summary pages that the CaseIH has. Both softwares works good. Agleader has very good software, but pricey $1200. Ted CenOH.
