Retarding Performance
To determine performance, read from Gross Weight down to % Effective Grade. Effective Grade equals actual % favorable grade plus 1% for
each 10 kg/metric ton (20 lb/ton) of Rolling Resistance. From this point, read horizontally to the curve with the highest attainable speed range.
Then, go down to Maximum Speed. Retarding effect on these curves represents full application of the retarder.
