Abstract: A track apparatus having a frame is provided. The track apparatus is mountable on a rotatable axle of a vehicle and includes a continuous flexible track and a drive wheel mountable to the rotatable axle of the vehicle for rotational movement therewith. The drive wheel drives the flexible track in response to rotation of the axle of the vehicle.

Abstract: A cutting blade for agricultural equipment defined by a truncated diamond configuration in plan view, where the cutting blade is made from a high strength plastic material, and where the leading or cutting edges thereof are beveled in a downward and outward direction. In an alternative embodiment, the cutting blade is in a "double diamond" shape, i.e. similar to two truncated diamond shapes at a right angle to each other. In any event, with either invention form, the cutting blade is reversible for extended use.The invention affords particular adaptability to what is presently and commercially known as home trimming and/or edging equipment; however, more far-reaching end purposes are achieved as, for example, the effective cutting of heavy grass, brush and scrub trees because of the unique shape and the material of each cutting blade per se.
