Does it have smaller than factory rear tires? For "calculated speed" it still has to know what size tires it has. Figure out how to check the Cal number for your tire size and verify it is correct on your tractor. Not your 2600.
I think you meant to ask if it has bigger tires than it was equipped with when it was new.
Bigger tires without recalibrating it would result in a displayed speed less than actual.
