I don't have that value, but I know it will depend upon the tire selection, inflation pressure, amount of weight on the 3pt hitch, as well as which adjustment hole the link arms are in.
The B2400 has two sets of holes for adjusting the height of the drawbar when it is in the full-down position. This height adjustment affects how high the drawbar is when in the full up position. It also affects how much weight can be lifted.
