STR46SPVGH • RIDE-ON POWER TROWEL — OPERATION MANUAL — REV. #0 (07/17/08) — PAGE 28
The STR46SPVGH trowel is equipped with a "Torque Converter"
which supplies torque to both the left and right gear boxes.
The function of the a torque converter is to automatically deliver the
correct amount of torque required by the trowel under all load
conditions. This enables the trowel to deliver the necessary torque
for float pan applications and the high rotor speeds required for
burnishing concrete.
The torque converter is of the variable pitch pulley type, (Figure 22)
connected by a drive belt.

to create a belt squeeze force transmitted at the pulley faces.
This condition functions as an automatic clutch.
