They definitely show those specs for that model. My guess is that the disclaimer covers differences in lift height, dump height, etc between the different tire type/sizes. The same machine with R1 and R4 tires will have slightly different actually FEL height specs since the tires are different heights. I doubt lift capacity would vary since that's simply a function of pump relief pressure (assuming same model loaders).That is a lot of weight for that size/weight tractor, but there are others that lift more at the same weight. For example, an LS R3039 is spec'd at lifting 2,250lbs to 92" and it weighs 2,700lbs without the FEL.
