  • Patent number: 5809759
    Abstract: A crop harvester has bristle guards (39) mounted on the cutter bar (14) as crop lifters and to capture fruit lost by dehiscence during cutting. Each bristle guard is a set of laterally oriented bristles (44). Dehisced fruit is swept into the header by a pickup reel (16) having bristle bats (74). The bristles (76) are supported on the leading side by a strip (78) of flexible belting. The belting protects the bristle against being cut by the cutter bar. The crops are supported against being pushed forward by the bristle bats (74) of the reel. The diameter is reduced to about one-half normal and the reel index in increased to provide an aggressive reel operation, ensuring that plants are properly engaged in the bristle guards for cutting.
