A riding mower (2) includes a cutting unit (6) suspended from a traction unit (4). Cutting unit (6) is suspended from a forwardly extending frame (8) by four suspension units (40-43). Each suspension unit includes an upwardly opening saddle member (44) in which a pin (51) carried on cutting unit (6) is received. At least some of the pins (51) are longitudinally constrained in the saddle members (44) to longitudinally couple cutting unit (6) to frame (8). This allows cutting unit (6) to move upwardly relative to frame (8) at each of the suspension units to allow the cutting unit (6) to tilt or float relative to frame (8).

A vegetation cutting apparatus, which comprises: (a) a base unit which is movable over the ground in a longitudinal direction; (b) a cutting unit having means for cutting vegetation; and (c) means for mounting the cutting unit on the base unit, wherein the mounting means comprises means for suspending the cutting unit from the base unit on at least two laterally spaced suspension points with the cutting unit free to move upwardly at each suspension point to allow the cutting unit to tilt side-to-side laterally relative to the base unit, wherein the suspending means comprises a suspension unit at each of the suspension points, wherein each suspension unit comprises a suspension member carried on the cutting unit which is received in an elongated vertical slot on the base unit to allow upward vertical movement of the cutting unit relative to the base unit at each of the suspension points, and wherein at least one of the suspension members on the base unit is also continuously longitudinally constrained in the vertical slot on the base unit to longitudinally couple the cutting unit to the base unit for movement therewith.
