Claim 13:
14. 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 a pin engagement mechanism provided on and configured to move in unison with the linkage to prevent linkage movement that would result in additional downward movement of the cutting deck relative to the wheels.
