ABSTRACT:
A seeder (20) includes a seed hopper (22) that feeds seed by gravity to a seed dispenser (24). The seed feed wheels (38) of the seeder are mounted in a seed metering tube (30) so that rotation of the seed feed wheels meters the output of the seeds. The seed feed wheels can be formed in segments (50and60) so that by matching different segments, different sizes of seed receiving detents can be used for dispensing the seeds. An adjustment bracket (72) shifts the seed feed wheels so that different sizes of detents can register with the openings of the seed metering tube (30), thereby achieving the desired matching of sizes of detents with the sizes of the seeds.
