Abstract: A grass cutting machine comprising a chassis including a chamber for receiving a cushion of air for supporting the chassis, a cutting member, a power source, a drive line for drivingly connecting the power source and the cutting member, a source of pressure air, and a grass collection device. The collection device comprises a receptacle for receiving cut grass and includes a base wall, an upper wall, and at least one side wall. The receptacle has at least one inlet disposed externally of the chamber and in the region of the base wall for entry of cut grass entrained in a stream of air directly into the receptacle part of at least the base wall includes an air permeable region to retain cut grass in the receptacle and to permit the said stream of air to be drawn through cut grass retained in the receptacle and through the air permeable region in the bases wall so as, to filter the air stream and compact the cut grass in the receptacle.

Abstract: A grass cutting machine includes a grass cutter, a motor for driving the grass cutter, a housing for supporting the machine above ground datum, collector for collecting grass cut by cutter, and a fan for establishing a flow of air. The collector for cut grass further includes a duct for directing cut grass entrained in a stream of air from the fan. The duct has a collection mouth at an upstream end thereof and disposed in the region of the ground datum, thereof, and a downstream end of the duct connected to the collector. At least one air-outlet aperture is disposed in the region of the collection mouth, each aperture serving to direct at least a portion of the stream of air downstream from the collection mouth so as to draw into the mouth cut grass and to transport the cut grass through the duct to the collector.

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 includes 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 the ground surface, 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 crosswise and displaced longitudinally relative to the vertical axis of the cutting blade and with respect to normal forward operational movement of the mower, a device 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 the ground surface to vary the height of cut of the cutting blade.

Abstract: This invention relates to grass cutting appliances. In particular a grass cutting appliance in the form of a lawn mower comprises a hood, a cutting member for rotation in a substantially horizontal plane within the hood, a handle for controlling directional movement of the appliance during a cutting operation, a power source disposed remotely from the cutting member and supported from the handle, and a drive line for drivingly connecting the power source and the cutting member.
