Abstract
A lawnmower with a tractor and a gang of mowers pivotally supported by the tractor for up and down motion when moving on the ground is provided. A mower support arm is pivoted on the tractor and has a pivot axis for each of the mowers, and a camming action is created by the up and down mower movement and that causes the pivot axis to move horizontally relative to the tractor to thereby avoid having the mowers move horizontally, and it maintains a constant spacing between the mowers and avoids having the mowers collide when moving up and down. Shorter length mowers can thus be used in the gang, thereby following the ground contour more closely.
