US Patent 7587886 Lawnmower with cutter deck locator assembly

A lawnmower cutter deck is fitted with a side-to-side deck locator comprises first and second laterally spaced bearings that are disposed longitudinally between the cutter deck and the lawnmower frame. Each of the bearings is laterally spaced from a corresponding stop when the deck is centered relative to a longitudinal centerline the frame and permits limited lateral movement of the cutter deck relative to the frame through a stroke corresponding to the width of the space. Each of the bearings is movable vertically along the corresponding stop so as to permit uninhibited vertical movement of the cutter deck relative to the frame and pivoting of the cutter deck about longitudinal and lateral axes. A fore and aft locator may also be provided and be connected to the cutter deck and to the frame to at least substantially prevent fore and aft movement of the cutter deck relative to the frame.
