+Last year I contacted a dealer in Montana that carried Montana tractor parts. Their service manager was extremely helpful identifying and solving a problem I was having with my R3644. I have tried downloading the parts manual for this tractor and Adobe keeps telling me the file is corrupted.. I inadvertently lost the dealer's name and number. I do know that it was a fairly large auto dealership as well as an ag. dealer. Would anyone out there happen to know the name and number of the dealership I'm talking about. I believe it starts with an S and has auto in it's name
