Just get a quote from the local distributors. Been that way since Hector was a pup. The only direct sales is if one is a qualified National Account (fleet users).
Heck I can't buy a new car/pick-up or suv directly from the manufacturer either - gotta go to the dealer. Same for a riding lawn mower. or a farm tractor
Life is just not fair - get used to it.
BTW - Started in the F/L business Dec. ' 67, that's the way it was back then. The. local dealer often will often suggest added features that will make your operation more productive, safer or features that reduces maintenance costs,, programs, services , finance options etc, etc after a survey of your operation.
