Claim 15:
16. A method for adjusting the cutting depth of a walk-behind lawnmower, the lawnmower having a cutting deck mounted on front and rear wheels and a handle assembly extending rearwardly from the cutting deck, the method comprising:
moving an adjustment lever;
translating a linkage in response to the motion of the adjustment lever;
rotating a first front bracket and a first rear bracket co-directionally in response to the translation of the linkage;
moving a front link and a rear link in response to the rotation of the first front bracket and first rear bracket;
rotating a second front bracket and a second rear bracket co-directionally in response to the motion of the front and the rear links;
moving a cutting deck vertically relative to the wheels in response to the rotation of the brackets;
inserting a locking pin into the cutting deck at a selected one of a plurality of longitudinally spaced locations along the cutting deck; and, engaging the locking pin with an engagement mechanism on the linkage to prevent linkage movement that would result in additional downward movement of the cutting deck relative to the wheels; and
wherein the locations are spaced so as to permit height adjustment of the cutting deck in increments of less than ½″.
