Material discharge apparatus is provided having a substantially upright chute which is extendable in its length and through which material operatively flows under gravity from an inlet to a discharge end. Control means are provided to control the discharge of the material from the chute, by controlling the length of the chute and the height of the discharge end relative to the surface onto which the material is discharged, to maintain the level of material in the chute within a predetermined range. |
