Gradeability/Speed/Rimpull To determine gradeability performance: Read from gross weight down to the percent of total resistance. Total resistance equals actual percent grade plus 1% for each 10 kg/metric ton (0 lb/ U.S. ton) of rolling resistance. From this weight-resistance point, read horizontally to the curve with the higest obtainable gear, then down to maximum speed. Usable rimpull will depend upon traction available and weight on drive wheels.
