GRANULAR MATERIAL APPLICATOR WITH SPEED COMPENSATOR ABSTRACT The specification discloses an applicator (10) for precisely dispensing granular materials, such as her- bicides, pesticides and the like, with improved control while compensating for the speed and travel direction of the implement carrying the applicator. The applicator (10) comprises a hopper (14) with an arcuate hopper bot- tom extension (40) and an internal feed rotor (42). The arcuate hopper bottom extension (40) is preferably inclined, and the openings (44) in the end preferably include straight lowermost sides oriented parallel to the rotational axis of the feed rotor (42) to obtain better flow control in conjunction with a revolving transfer means (54) located beneath and closely adjacent to the bottom end of the hopper. The revolving transfer assembly (54) preferably includes a plurality of rollers (56) for individually receiving material from the ope- nings (44) in the hopper and distributing it for applica- tion. The feed rotor (42) and transfer assembly (54) are vertically and laterally offset and are interconnected for counter rotation in unison responsive to travel of the applicator (10) such that the rate of material application is directly proportional to the speed of travel.
