Abstract
A mower, such as a riding mower, has two side cutting units and a front cutting unit operatively connected to a traction frame. Each side cutting unit can pivot about a substantially vertical axis relative to the traction frame when impact shocks occur on the outer sides of the cutting units. A shock absorber cushions and absorbs such impact shocks, and resists the pivoting motion of the side cutting units, in a bi-directional fashion to be effective during forward or reverse motion of the traction frame.
