  • Patent number: 12180674
    Abstract: A land plane with a ripper, including a plane portion including at least two cutter bars and a ripper mechanism having a ripper bar assembly having ripper teeth that are shiftable between a downwardly extended orientation in which the ripper teeth are biased to extend downwardly beyond the at least two cutter bars thereby facilitating ground engaging contact of the ripper teeth and a retracted orientation in which the ripper teeth are above the at least two cutter bars. The ripper mechanism further includes a latching mechanism and a reset bar extending outwardly away from the plane portion and coupled to the latching mechanism. The reset bar is shiftable between a first position wherein the ripper teeth are secured in the retracted orientation by the latching mechanism and a second position wherein the ripper teeth are biased toward the extended position by the latching mechanism.

  • Patent number: 12152357
    Abstract: A snow plow cutting edge, including at least one elongate backing plate removably fastened to a lower edge of a snow plow moldboard or to a cutting edge trip mechanism. The elongate backing plate has a long axis and a plurality of biasing member engaging structures. Slide bars are engaged to the elongate backing plate. The slide bars are arranged proximate one another along the long axis of the elongate backing plate and are slidable generally perpendicular to the long axis. Biasing members are engaged between the biasing member engaging structures and the slide bars such that the slide bars are biased generally perpendicular to the long axis toward a surface to be cleared of snow. Replaceable cutting edge sections are removably attached to one of the plurality of slide bars and located adjacent at least one of the other replaceable cutting edge sections.

  • Publication number: 20240337081
    Abstract: A wing plow including a main moldboard; a first side plate secured to a first end of the main moldboard by a first hinge having a first vertical axis of rotation and a second side plate secured to a second opposing end of the main moldboard by a second hinge having a second vertical axis of rotation. The wing plow further includes a first actuator driving the first side plate and a second actuator driving the second side plate. Optionally, a programmable logic controller (PLC) is operably coupled to the first actuator and the second actuator and is programmed to control the first actuator and the second actuator to position the first side plate and the second side plate based on a sensed angle of orientation of the main moldboard and a plurality of modes that are operator selectable.

  • Publication number: 20240122115
    Abstract: A collection system for a mower, including a collector, that has a mounting panel that is removably coupleable to the mower at a discharge of a mower deck and a collecting enclosure that is hingedly coupled to the mounting panel such that the mounting panel and the collecting enclosure together enclose a collecting volume that receives discharged matter. The collecting enclosure is shiftable about a hinge axis between a discharge collecting orientation in which the collecting enclosure abuts the mounting panel and is positioned to receive the discharged matter therein through an opening of the mounting panel and an emptying orientation in which the collecting enclosure is raised by rotation about the hinge axis such that the discharged material exits the enclosure by gravity.

  • Patent number: 11472331
    Abstract: The laser light safety guide to assist in guiding a prime mover utilize for snowplowing including a laser that can be mounted within a cab of the prime mover and oriented to emit a visible laser beam directed through a transparent structure the prime mover. The laser light safety guide further comprises a shielding structure opaque to the visible laser beam that is trimmable or adjustable to enclose a space extending from a portion of the laser from which the visible laser beam is emitted to the transparent structure the prime mover. The shielding structure mitigates or contains reflection of the visible laser beam from an interior surface of the transparent structure.

  • Patent number: 11131075
    Abstract: An implement attachment adapter, including a centrally located top clevis; two spaced apart lower clevises located below the centrally located top clevis and on opposing sides of a line extending vertically through the top clevis. The two spaced apart lower clevises being are recessed into or behind a first face of a flat plate. The flat plate further includes side tabs located proximate each horizontal peripheral edge thereof extending outwardly away from the first face of the plate. A bottom tab extends outwardly downwardly away from the first face at an obtuse angle relative to the plate. A top bar extends across proximate a top portion of the plate and outwardly away from the first face of the plate and is oriented at an acute angle to the plate. The plate further presents engagement apertures and a second face opposing the first face to which the implement may be coupled.
