  • Publication number: 20230276741
    Abstract: A blade has a flat body with a first side, a second side, an aperture extending between the first side and the second side, and an outer peripheral edge. The aperture has a central axis defining an axis of rotation. A plurality of teeth is formed along a portion of the outer peripheral edge forming a cutting edge. Each of the teeth has a tip that is a radial outermost part of the flat body in a plane defined by the tip and the central axis of the aperture. The cutting edge has a first end and a second end. The distance between each tip of the teeth increases from the first end of the cutting edge to the second end thereof. The distance between each tip and the central axis increases from the first end of the cutting edge to the second end thereof.

  • Patent number: 11647699
    Abstract: A tree saw attachment for a modular landscape trimmer is disclosed. In one embodiment, the tree saw attachment is provided with a drive unit having a drive shaft operably connectable to a motive source and a transmission operably connected to the drive shaft. An anvil is connected to and extending from an output side of the transmission of the drive unit, and a blade is connected to the output shaft of the transmission. The blade has an arcuate outer peripheral edge with teeth formed along a portion thereof forming a cutting edge so as the output shaft is rotated, the distance between the cutting edge and a central axis of the output shaft increases until the blade has substantially completed one rotation. Rotation of the blade causes the blade to move transversely with respect to the anvil to engage and cut material positioned between the blade and the anvil.

  • Patent number: 10300973
    Abstract: A taillight assembly including a support member, a right light assembly, a right lens assembly, left light assembly, and a left lens assembly. The right and left light assemblies are mounted to a light supporting portion of the support member. The right assembly includes a first light source oriented to direct a first beam of light in a rearward direction and a second light source oriented to direct a second beam of light in a rightward direction. The left light assembly includes third light source oriented to direct a third beam of light in rearward direction and a fourth light source oriented to direct a fourth beam of light in a leftward direction. The right and left lens assemblies are mounted to the light supporting portion to house the right and left light assemblies, respectively, and cooperate to disperse the first, second, third, and fourth beams of light 270 degrees horizontally.
