ABSTRACT:
An air-cushion lawn mower has a rotary cutting blade shrouded by a hood. The mower has a fan wheel rotatable about the same axis as the blade, and both the blade and the fan wheel are driven by a motor mounted on the hood. The front part of the hood with respect to the normal direction of travel of the mower, has projections which support a freely rotatable roller which acts to reduce the frictional resistance to forward motion when the mower is used to cut relatively long blades of grass.
