Embodiment Construction

[0023] figure 1 Is a perspective view of the mower body 10 of the present invention, with conventional handles and forage collection bins or bags omitted for clarity. The lawn mower shown is of the type known as a "rotary mower" in which a motor turns the cutting blade about a vertical axis, either by direct drive action or by an indirect drive mechanism in which the blade Mounted on a motor shaft, in an indirect drive mechanism, the motor drives a belt which in turn drives a pulley on which the cutting blade is mounted. The body 10 comprises a platform 11 of the type described above, on which most of the functional structures of the mower, such as the electric motor, are mounted. For example: Platform 11 includes a front (in use) axle assembly (covered) carrying an axle on which a pair of front wheels 12 are mounted. Likewise, at the rear of the mower there is a pair of rear wheels 13 mounted on a rear axle carried by a rear axle assembly (covered).

Abstract

The present invention relates to improvements in or relating to vegetation cutter apparatus. In particular, it relates to improvements in construction and manufacture of housings for lawn mowers. The lawnmower of the inveniton has a deck with a lower surface defining a cutting chamber, a cutting element mounted within the cutting chamber, a motor assembly driving the cutter element, the motor being mounted on an upper surface of the deck, wherein the vegetation cutting apparatus further comprises a discharge chute having a discharge chute inlet in communication with the cutting chamber and a discharge chute outlet, a cover covering at least a portion of the motor assembly, and a pivotable deflector guard biased into a closed configuration against the discharge chute outlet. The discharge chute comprises a chute floor, chute sides and a chute roof. The present invention is characterised in that at least a portion of the chute roof is formed by a portion of the motor cover.

Description

technical field [0001] The present invention relates to improvements in ground working equipment. In particular, it relates to improvements in the construction and manufacture of housings for ground working equipment including debris ejection, especially lawnmowers, scarifiers and vertical cutters. Background technique [0002] Devices such as lawn mowers are typically complex products assembled from multiple injection molded plastic parts. In the center of these parts is the platform. The platform is the installation part of most components of the mower, especially the installation of the prime mover (usually an electric motor or a small gasoline engine) for the device. In the rotary electric lawn mower of the present invention, the motor is installed on the upper surface of the platform. Some lawn mowers have direct drives, in which case the motor's drive shaft passes through a hole in the deck. An elongated cutting blade is mounted on the end of the drive shaft within...
