Abstract
An extendable section, for attachment to a fixed screed, may include a rotatable shaft, and a power receiving component attached to the rotatable shaft. The power receiving component may receive power generated during rotation of a drive shaft, and generate torque and speed for rotating the rotatable shaft. Increasing the driving rotational speed of the drive shaft may increase a driven rotational speed of the rotatable shaft, and decreasing the driving rotational speed of the drive shaft may decrease the driven rotational speed of the rotatable shaft.
