TURF OVERSEEDING APPARATUS AND METHODS

摘要

A seeder ( 10 ) includes multiple cutting head units ( 30 ) pivotally mounted to a jack shaft ( 24 ) of a frame ( 12 ) and spring biased downwardly by hold downs ( 80 ). Each multiple cutting head unit ( 30 ) includes multiple roller blades ( 36 ) received on an axle ( 34 ) rotatably mounted in a carrier ( 32 ) and in gearing relation to the jack shaft ( 24 ). The roller blades ( 36 ) include a series of oppositely formed, circumferentially spaced radially extending indentations ( 36 a) extending from a continuous, smooth periphery at a constant extent from the axle ( 34 ). Fingers ( 46 ) extending between the roller blades ( 36 ) are pivotally mounted to the carrier ( 32 ) to adjust the depth of the slits formed by the roller blades ( 36 ). Each hose ( 98 ) extending from a seed box ( 96 ) diverts seed into adjacent slits immediately after the roller blades ( 36 ).
