Two obstacles to native forb seed production and harvest are indeterminate ripening and light pappus-bearing seed evolved for wind dispersal. A rigid pipe rake installed on the hood of the Flail-Vac effectively agitated the floral heads knocking seeds loose and allowing them to be sucked in by the suction created from the rotating brushes. This farm equipment is suitable for all types of soils. However plants were frequently hung up on the pipes and dragged until they were broken or uprooted. An elongated hollow housing is provided including front and rear sides and opposite ends. In addition, a lower partial cylindrical shield portion 62 is disposed within the housing 16 and extends rearwardly from the marginal portion 50 and curves upwardly toward its rear end. We modified a Flail-Vac Seed Stripper by mounting heavy loops of chain to the front to provide agitation of the floral canopy to disarticulate mature seed from the flowers of hoary aster (Machaeranthera canescens). Accordingly, previously known forms of seed harvesters are expensive to purchase and require considerable maintenance. Abstract. The force of friction strips the seed off the stalk. ... vacuum hose is a 4 inch suction hose with smooth insides to facilitate seed flow and prevent bridging. The plants produce numerous indeterminately ripening flowers that are scattered throughout the plant (not just on the periphery of the canopy). Ripe seed was knocked off of the flowers and the loose seed was caught by the air current created by the rotating brush. This process unfortunately causes significant damage to mature and immature flowers and allows for about two harvests before the canopy is effectively destroyed. In 2015 we experimented with two modifications to the standard Flail-Vac harvester in an attempt to increase yields of pappus-bearing seed. We saw a 5-fold increase in seed yields compared to yields obtained with a standard Flail-Vac and a significant reduction in seed processing time compared to our previous harvest experience. However, the outlet 48 is defined between the members 28 and 30 at the upper marginal portion of the extension 60 and accordingly, air passing through the housing 16 from the inlet 46 to the outlet 48 moves in the direction of the phantom lines 64 up over the upper portion of the brush 54 and rearward beneath the extension 60 before making a 180° turn forwardly and upwardly along the extension 60 toward the outlet 48.
