ABSTRACT:
A gauge for determining the height to which grass should be cut is configured as an elongated strip having a reference edge at one end adapted to be placed against the ground. On the strip there are plural sets of different indicia, with two longitudinally spaced apart corresponding discrete markings in each set, one for grass height before cutting and the other for height after cutting. The distances of the two markings in each set from the reference edge follow a three to two ratio. The correspondence between markings is indicated either by color or by alphanumeric symbols.
