ABSTRACT:
An apparatus for precision measurements of the clearance between the blades of a lawn mower and the ground. The apparatus includes a groomer gage and bed knife gage mounted on a plate and adapted to be positioned against the rollers of a mower during the taking of measurements. The plate, when positioned against the rollers simulates the position of the ground. The gages on the plate are positioned on the plate in a manner allowing the respective shafts of the groomer gage and bed knife gage to contact the groomer member and bed knife, respectively. The distance the respective shafts are displaced to cause contact with the groomer member and the bed knife corresponds to the ground clearance of the groomer member and the bed knife, respectively. The respective distances corresponding to the ground clearance of the groomer member and the bed knife are displayed by the groomer gage and the bed knife gage, respectively. The simultaneous measurement of the ground clearance of the groomer member and the bed knife facilitates the adjustment of the mower necessary to achieve the desired cutting height.
