- 12 - ABSTRACT This invention relates to rotary-type lawn mowers which may be supported on either a cushion of air (a hover mower) or on a wheeled/roller system. In more detail a rotary mower according to the invention comprises a hood, a cutting blade disposed within the hood and mounted for rotation about a substantially vertical axis, a power unit for driving the cutting blade in a cutting mode, above ground datum, at least one mower support rolling member disposed externally of that area ascribed during rotation of the cutting blade, a support lever rotatably supporting at least one rolling member mounted with its rotational axis of symmetry disposed athwartship and displaced longitudinally relative to the vertical axis of the cutting blade and with respect to normal forward operational movement of the mower, means for hingedly connecting the support lever to a part of the mower at a position remote from the mower support rolling member whereby angular movement of the support lever about the rotational axis of the said rolling member creates displacement of the cutting blade relative to ground datum to vary the height of cut of the cutting blade.
