Retarding Performance
To determine retarding performance: Add lengths of all
downhill segments and, using this total, refer to proper
retarding chart. Read from gross weight down to the percent
effective grade. Effective grade equals actual % grade minus
1% for each 10 kg/t (20 lb/ton) of rolling resistance. From this
weight-effective grade point, read horizontally to the curve
with the highest obtainable gear, then down to maximum
descent speed brakes can properly handle without exceeding

cooling capacity. The following charts are based on these
conditions: 32° C (90° F) ambient temperature, at sea level,
with 24.00 R35 tires.
NOTE: Select the proper gear to maintain engine rpm at the highest

possible level, without overspeeding the engine. If cooling oil
overheats, reduce ground speed to allow transmission to shift to
the next lower speed range.

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/t (20 lb/ton)
of rolling resistance. From this weight-resistance point, read

horizontally to the curve with the highest obtainable gear, then
down to maximum speed. Usable rimpull will depend upon
traction available and weight on drive wheels.
