1,144,825. Seed sowing machines. MASSEY FERGUSON Inc. 14 June, 1966 [15 June, 1965], No. 26366/66. Heading A1D. Seeds are carried by centrifugal force from a hopper into chambers 59 of an accelerator member 48 and pass into cells 64 of a metering member 60 which is rotated in the same direction as the member 48 but at a slower speed. Each seed is ejected from an opening 38 by centrifugal force. Rotatable clearance wheels 67 prevent more than one seed entering each cell 64. The wheels 67 may be omitted or may be replaced by brushes.
