I agree with bro., that you will be just fine with which ever baler you have. We towed a NCM from our farms (a 3.5 mile drive at road speed with a Case LA all the time with no problems.
An interesting note is the Lit. that I posted here about the older NL Case baler. It was a high speed stationary baler, and the lit. proves it LOL. If a company distributed lit. like that today the lawyers would have a field day. (if they knew what a field day was) HeHe. I like the third pic. with the baler backed into the hay mow with the wisconsin engine on it. Today one spark and barn burns down, Case woulda built a new barn, paid for loss income, pain&suffering, and who knows what else.
I just threw these pics from Case Lit Form #A28453H printed in 1953, and price book 1955.
