You're thinking of the 5000 series where the E models are basic, and M are deluxe (plus made in the U.S.). For whatever reason, the 4000 series is different and the M is the base model, while the R is deluxe. I think they're light (3,700lbs) for the horsepower, and have a weak loader (2,200lbs to 110").
You're right. You would think they would keep that designation the same over all lines. Oh well, who can ever figure out how big corporations think.
