TRAVEL PERFORMANCE
To determine travel performance: Read from gross weight down to the percent of total resistance. From this weight-resistance point,
read horizontally to the curve with the highest obtainable speed range, then down to maximum speed. Usable rimpull depends upon
traction available and weight on drive wheels.
To determine brake performance: These curves are provided to establish the maximum speed and gearshift position for safer
descents on roads with a given distance. Read from gross weight down to the percent of total resistance. From this weight resistance
point, read horizontally to the curve with the highest obtainable speed range, then down to maximum descent speed the brakes can
safely handle without exceeding cooling capacity.
