Abstract
A grass mowing or cutting machine suitable for towing by general application vehicles is disclosed. The machine is operated by its advance and comprises a wheeled frame having a horizontal cutting disc which rotates about a vertical axis. A drive mechanism connects the cutting disc to the wheel(s) of the wheeled frame so that when the mowing apparatus is pulled or pushed, the cutting disc will be rotated by the rotation of the wheel(s). A gearing mechanism is typically provided between the cutting disc and the wheel(s). The cutting disc is preferably of web-like construction and includes aerodynamics portions to exert a downward force on the disc as it rotates through the air. The moving apparatus is designed for relatively high speed towing.

Mowing apparatus for cutting grass or the like, the mowing apparatus being adapted in use to be pulled or pushed by a vehicle, comprising:
- a wheeled frame;
- a cutting member mounted for rotation about a generally vertical axis;
- drive means connected between at least one wheel of the wheeled frame and the cutting member whereby the cutting member is located by rotation of the wheel(s);
- wherein the cutting member comprises a central hub member, a plurality of equally spaced, generally flat, radial arm members having their inner ends connected to the hub member, each blade member having an upswept portion along its trailing edge such that a downward force is exerted on the blade when it rotates rapidly through air;
- and
- a plurality of connection members each connected between a respective pair of adjacent arm members and each being adapted to have a blade member connected thereto.
