Abstract: A depth of cut/height adjuster for a grass treatment insert mounted to rotate in a frame supported on front and rear rollers. The adjuster permits an operator to vary the height of a frame relative to the front roller and thereby adjust the depth of cut of the grass treatment insert. The depth/height adjuster includes a frame mount block for attachment to the frame. The frame mounting block has a throughbore in which is threaded a shaft. A roller mounting block for attachment to the front roller is rotatably mounted on a lower end of the shaft. A vertical gauge attached to the roller mounting block when aligned with a marker on the frame mounting block (such as the bottom edge) indicates the relative distance between the roller mounting block and frame mounting block which is correlated with a height setting of the grass treatment insert.

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.

Abstract: A fully-adjustable lightweight trimmer attachment assembly (10) broadly comprises a wheel (14), a rod (16) extending from the wheel (14), and a mounting mechanism (18) for rotationally mounting the rod (16) to a trimmer (12). The rod (16) preferably includes an axle section (16a) through the wheel (14), a trailing section (16b) perpendicular to the axle section (16a), a centering section (16c) parallel to the axle section (16a), and a vertical section (16d) aligned at ninety degrees to the centering section (16c) and at sixty degrees to the trailing section (16b). With the vertical section (16d) vertical, the trailing section (16b) forces the wheel (14) to follow the vertical section (16d), providing a castering effect. The mounting mechanism (18) includes a rod mount (30) rotationally secured to the vertical section (16d) and a shaft mount (32) operable to be secured to the trimmer (12) and rotate about the rod mount (30).

Abstract: The attachment comprises a resilient member in communication between the wheel of the attachment and the weed trimmer shaft, which reduces vibration experienced by the weed trimmer operator. The resilient member further allows the operator to tap the trimmer head against the ground to release additional trimming line in a normal fashion as if the wheeled attachment were not in use.

Abstract: A riser attachment for mower height adjustment includes a bracket attachable to a mower and a roller removably attachable to the brackets. Each bracket includes a cavity therein which receives an arm extending from a support structure which rotatably supports each end of the roller such as through an axle passing through a collar in an interface to which the arm is connected. The roller or other bearing surface extends below a mower support plane in which primary ground support structures of the mower are located. The roller or other bearing surface of the riser attachment thus elevates a cutting reel of the mower slightly to provide a second cutting height for the mower. This second cutting height can be adjusted through height adjusters which control a distance that the arms extend into the cavities of the brackets. Levers are rotatable to secure or release the arms within the cavities.

Abstract: An apparatus and method for adjusting the height of a wheel, particularly a caster wheel, in relation to a structure such as a mower deck of a lawnmower includes a frame member, a hollow guide member, a transverse element, and a lever.

Spaced recesses are formed in the angled section and arranged along the adjustment direction. The guide member and transverse element are attached to the structure. The angled section is slidable through the guide member. The lever is pivotably connected to the transverse element and includes a locking element. By pivoting the lever, the locking element can be brought into engagement with a selected one of the recesses to fix the angled section at a desired position relative to the guide member and thus the height of the structure relative to a ground surface over which the caster wheel or wheels roll.
