or cup held beneath the lower hopper opening 43 c preferably the drive assembly 32 includes a prime mover in the form of an electrically driven motor 65 fig3 mounted in a vertical orientation by a c shaped bracket 66 bolted to the structural frame 29 the motor 65 has an upwardly directed drive shaft 66a extending into a fluid drive unit 67 of the type that is well known in the art and is preferably a model fv supplied by fluid drive engineering co of wilmette ill the drive unit 67 has a housing 68 and a hollow shaft 69 that receives and is affixed to the motor drive shaft 66a by a key 70 or the like the shaft 69 extends into the interior of the housing 68 and is connected to a drive vane not shown a complimentary drive vane not shown is attached to the interior of the housing 68 and the housing is filled with oil that transmits drive force from the shaft 69 to the housing 68 which is rotatable with respect to the shaft 69 a pulley 71 is formed in the bottom of the housing 68 and is connected to a shank 75 fig3 of the auger 30 by means of a belt and pulley drive train shown generally at 76 thus the fluid drive unit 67 provides an indirect drive linkage between electric motor 65 and the auger 30 prior art devices to the present invention did not include an indirect connection between the motor 65 and auger 30 but instead the motor was directly connected to.
