Zusammenfassung:	Clean grain in compartment 26 is discharged by unloading augers driven by sprockets 208, 210 which are driven by a chain 204 coupled to a driving sprocket 202. A swing arm 190 is pivotted to the chassis at 192 and is swingable downwards by a hydraulic cylinder 198 against a biassing spring 194. A constantly rotating sheave 138 is connected by a V-belt 139 to a second sheave 140 which is coupled to the sprocket 202. The sheave 140 is carried by the arm 190 so that when the arm is swung down the belt 139 is tightened and drive is transmitted. Retraction of the arm by the spring 194 causes belt guard 214 to disengage the belt from sheave 138.
