ABSTRACT:
An improved sheep shearing apparatus comprising a motor suspended from an overhead member by a suspension apparatus, the motor having a drive shaft which is oriented vertically downward and is connected via a flexible shaft assembly to a clipper head assembly. The flexible shaft assembly is characterized as having a sufficient length and torsion resistance such that wherein the clipper head assembly encounters a load during the shearing procedure the flexible shaft assembly resists twisting. The length of the flexible shaft assembly is approximately equal to the vertical distance between the motor and the working surface on which the sheep is to be sheared.
