Rotating cylindrical flailing vegetation cutter
View Patent ↗A rotating cylindrical flailing vegetation cutter, which includes a power rotated shaft having a cross-sectional profile. Disks are provided having a central aperture adapted to slide over the shaft and non-rotatably engage the cross-sectional profile. Each of the disks remain separate from and unattached to the shaft. Spacers are secured between the disks to maintain relative lateral spacing of the disks and form a disk assembly. Flail members are carried by the disk assembly.
1. An apparatus comprising:
a power rotated shaft having a polygonal cross-sectional profile with an exterior surface having at least three connected engagement surfaces;
disks laterally spaced along the shaft and having a central aperture adapted to slide over the shaft and non-rotatably engage the cross-sectional profile, the central aperture being polygonal with an equal number of matching engagement surfaces, each of the disks remaining separate from and unattached to the shaft;
spacers secured between the disks to maintain relative lateral spacing of the disks and form a disk assembly, the spacers being in the form of spacer sleeves spaced radially in relation to the shaft and overlying bolts, and the bolts coupling each of the disks with an adjacent disk to form disk pairings; and
at least three pivotally mounted flail members circumferentially and laterally spaced in relation to each disk of the disk assembly, each of the at least three flail members having a mounting aperture, the mounting aperture overlying one of the bolts, each of the flail members being maintained in a desired lateral spacing on the one of the bolts by at least one of the spacer sleeves, and the flail members positioned between each of the disk pairings being laterally offset from the flail members positioned between an adjacent one of the disk pairings.
2. The apparatus as defined in claim 1 , wherein the shaft is square in cross-section and has four connected engagement surfaces.
