By Adjusting Ground Wheel Or Skid Relative To Carrier Patents (Class 56/17.2)
  • Patent number: 11252867
    Abstract: A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, and an operating arm connected to the first end of the main body. The distance in the horizontal direction between the axial central line of the cylindrical gripping portion of the operating arm and the axes of the elongated handle of the main body along the length direction is less than 5 cm. Because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the operator feels more comfortable during the transporting process, the volume of lawncare apparatus during transporting is reduced and the convenience of transporting is improved.

  • Patent number: 11224163
    Abstract: A rotary cutter for cutting grass, brush, shrubs, bushes, trees, and other vegetation, and a method of using the same. The cutter includes a bi-fold door proximate to an open front portion of the cutter's deck, which defines an open cutting area. The bi-fold door moves between a closed position where it shields the cutting area and an open position where it exposes the cutting area. The bi-fold door includes a front cover rotatably coupled to a rear cover via the first hinge, with the rear cover being rotatably coupled to the deck via the second hinge. The cutter also includes a first ramp and second ramp flanking the open front portion of the deck. Protrusions of the bi-fold door slide along inclined surfaces of the ramps as the bi-fold door moves between the closed position and the open position.

  • Patent number: 10939615
    Abstract: A mower deck can include a linkage that enables adjusting the height of the mower deck with a single action. The mower deck can include a rolling mechanism support arm at each corner and a coupling mechanism that extends between the front and rear rolling mechanism support arms on each side of the mower deck. A shaft can extend between the two front rolling mechanism support arms and can be rotated via an actuator. When the shaft is rotated, the front rolling mechanism support arms will rotate in unison, and the coupling mechanisms will cause the rear rolling mechanism support arms to also rotate in unison. In this way, a single action can cause the height of the mower deck to be adjusted.

  • Patent number: 9192100
    Abstract: An apparatus that removes matted clumps of wet grass from a lawnmower discharge port includes a hinge having a first flap secured to a trailing edge of the discharge port. A second flap is secured to a rigid flat plate about mid-length of the plate. The plate has a position of repose normal to a longitudinal axis of symmetry of the lawnmower and a pivoted position parallel to the longitudinal axis. The position of repose allows grass clippings propelled by a rotating blade to travel without obstruction toward the discharge port. A cord is secured to the plate so that a lawnmower operator can cause the plate to pivot from its position of repose to drive matted clippings through the discharge port. A torsion spring resists the pivoting of the plate and returns the plate to its position of repose when the cord is released by the operator.

  • Patent number: 8069639
    Abstract: A mower is provided that includes a height-adjuster assembly that adjustably connects the ground engaging wheel to the housing of the mower at an adjustable height from the ground. The height-adjuster assembly includes a bracket fixed to the housing, an arm, a sleeve, a wheel mount, a pin, and a handle. The arm is rotatably mounted relative to the housing and the bracket about a pivot point. The sleeve is fixed to the arm for rotation with the arm relative to the housing and the bracket about the pivot point. A handle overlays the pin and the sleeve. The handle is configured to be grasped by a user for movement along a first direction to move the pin from a first position into a second position. Upon reaching the second position, the handle and the sleeve can be rotated to rotate the ground engaging wheel relative to the housing.

  • Patent number: 8001754
    Abstract: A height adjuster mechanism for mounting on a frame of a grass and/or ground treatment machine to vary the height of the frame relative to a ground-engaging roller assembly and thereby adjust the height setting of a grass and/or ground treatment module mounted on the frame. The mechanism includes an open-topped housing provided on a rotary adjuster and having an upper surface which defines a height adjustment reference datum level. An insert is movable up and down within the open-topped housing in which the upper surface of the insert can be adjusted to be substantially flush or coplanar with the upper surface of the open-topped housing so as to set a datum level of the treatment module. Means are provided for determining the extent of angular adjustment of the rotary adjuster so as to set any required height adjustment of the treatment module.

  • Patent number: 7958709
    Abstract: A grass treatment device height adjustment assembly for adjusting the height of a grass treatment tool above ground level includes a height adjustment mechanism and an elongate rotational element, such as a roller, having first and second ends. The rotational element has an axle extending substantially along the longitudinal axis of the element about which the element rotates. The height adjustment mechanism includes a rotatable member connected to the axle of the rotational element wherein the rotatable member is associated with a second fixed axis of rotation that is substantially parallel to but offset relative to the first rotational axis. The second axis of rotation enables the height adjustment mechanism to adjust the position of the first axis of rotation relative to the second axis of rotation.

  • Patent number: 7958943
    Abstract: A wheel mounting and height adjustment mechanism for use with a power equipment unit/implement such as a lawn mower. In one embodiment, the mechanism may include a block defining a plurality of bores, each bore to selectively receive an axle of a wheel assembly. A plate member may be provided in or near the block. The plate member may include a plurality of elongate cutouts such that a separate cutout is selectively alignable with each of the plurality of bores. When the plate member is in a disengaged position such that a first portion of each cutout is aligned with its respective bore, each cutout permits the axle to fully enter its respective bore. However, when the plate member is moved to an engaged position, each cutout may engage the axle to capture the respective wheel assembly.
