I recently bought ANOTHER box of old CaseIH training / marketing / educational / video cassettes at an auction. Models covered are the MX180, MX200, MX220, MX240, MX270.
Dad's cousin, lifelong AC and CASE farmers, called this series "uglier than a pregnant belly button" in reference to their grill soon after they came out. Hard telling how many of this series and newer Magnums they've owned since. We've got a MX 240 in the shed. Certainly have their fair share of quirks over this old boxcars, but they're alright tractors.
