Abstract
Abstract The assembly is so configured as to use common parts, whereby another assembly, having a different gear ratio, can be formed using the selfsame common parts. Only different gears, and a different frame is required to form the alternative assembly having the other gear ratio. Accordingly, stocking of discrete parts for the differing assemblies is greatly reduced.
