Abstract:
An adjustment mechanism for setting the cut height of a deck of a vegetation cutting device, the mechanism comprising:a) a first bracket attached to the deck; b) a plurality of vertically spaced openings provided in the first bracket; c) a mounting means attached to the deck and spaced from the first bracket; d) a plurality of groups of openings provided in the mounting means with each group corresponding to one of the vertically spaced openings in the first bracket; e) a positioning arm having first and second end portions and an intermediate portion; f) means for releasably pivotally connecting the first end portion of the positioning arm with any selected one of the vertically spaced openings provided in the first bracket; g) means for releasably fastening the intermediate portion of the positioning arm with any selected one of the openings of the corresponding groups of openings in the mounting means; h) a second bracket joined to the second end portion of the arm; and i) a ground engaging wheel rotatably carried by the second bracket, whereby changing the opening within the corresponding groups of openings with which the intermediate portion of the positioning arm is fastened changes the vertical angular orientation of the positioning arm with respect to the deck, and hence the cut height of the deck and, each opening in the first bracket corresponding with one of the groups of openings in the mounting means to provide different ranges of deck cut heights, the groups of openings being spaced from one another and at least one of the groups being at least laterally offset from at least another of the groups so as to enable association of the lowest to highest range of cut height among the groups.
