General Description

For the CT product line of trowels, engine power is
transferred through a centrifugal clutch and V-belt to the
gearcase and down to the trowel blades. The four trowel
blades are mounted on a spider assembly mounted on the
gearcase output shaft. The spider assembly adjusts the
trowel angle by being raised by the yoke-trowel blade lift.
The trowels can be tilted from 0° - 15 °. The speed
of the trowels ranges from 60-165 rpm, depending on
the model.
