  • Patent number: 11014266
    Abstract: A cutting system for slabs which includes a longitudinal guide having a pair of surfaces opposite to each other, the pair made up of a lower surface and an opposite upper surface, a suction cup coupled to the lower surface of the longitudinal guide suitable to selectively adhere to a slab and defining a contact surface of the longitudinal guide on the slab, the longitudinal guide further including a pair of rails parallel to each other coupled to the upper surface of the longitudinal guide and suitable for slidably coupling to a scoring slider. The rails are arranged on opposite sides with respect to a median plane of the suction cup perpendicular to the contact surface thereof.

  • Patent number: 9605406
    Abstract: An apparatus for cutting an edging trench around a landscape bed is constructed with a cutting blade that is rotated to help move the apparatus in the desired direction of travel while being operated to create an edging trench. The machine can be constructed in self-propelled, non-self-propelled or manually operated stick forms. The apparatus has a cutting blade that is configured in a cone-shaped manner with the narrow diameter located toward the center of the apparatus. The rotor is formed with a pair of thin slicing blades mounted on a spline shaft removable from the apparatus for maintenance. A first slicing blade shears the grass along the top of the trench and forms a vertical wall, while a second slicing blade forms a sloped wall. Displaced soil is discharged from the cutting blade and spread directly over the adjacent landscape bed to eliminate the need for subsequent clean-up operations.

  • Publication number: 20100224378
    Abstract: An edger has a main frame that can be advanced controllably relative to a subjacent terrain, a cutting assembly on the main frame, a drive for rotating the cutting assembly around a first axis, and material repositioning structure on at least one of the main frame and cutting assembly. The cutting assembly is configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation. The material repositioning structure controllably repositions material dislodged from underlying terrain by the cutting assembly to thereby avoid accumulation of dislodged material upon the edger as the edger is operated.

  • Patent number: 7059107
    Abstract: An edger assembly for use with a mechanized vehicle includes a mechanized vehicle, laterally adjustable shafts extending laterally outwardly on both sides of the vehicle, and dual elongated arms attached at each end of the shafts each generally perpendicular to the shafts. The edger assembly also includes an edging assembly attached to each arm wherein the edging assembly has a blade. Further, the edger assembly includes a protecting arm connected to the edger and slidably positioned to engage an object prior to blade contact and a mechanical linkage. The mechanical linkage can be constructed and arranged to move in response to protecting arm movement, where movement of the mechanical linkage moves the blade from an edging position to a non-edging position.

  • Patent number: 6116349
    Abstract: A device for trimming the edge of a lawn device comprises a rotary cutter which, in use, rotates about an axis which is substantially horizontal with respect to the ground. The device further comprises a guide which is mounted to extend, in use, in a substantially vertical downward direction to a depth greater than or substantially equal to the depth to which the rotary cutter extends. The guide is preferably mounted to extend, in use, in a substantially vertical downward direction to a depth greater than or substantially equal to the depth to which the rotary cutter extends.
