Abstract

A multi-function grass care and ground surface maintenance machine comprising a self-propelling rotary lawn mower with a dual purpose rotary cutting blade (9d Figure 9), comprising internal water chambers or channels (7c, Figure 7) fed via a water pump (7a, Figure 7) and a centralised permanently fixed impeller (9d Figure 9) to collect water and simultaneously pressurise water via an integral extended circular housing (9c Figure 9) or tubular column. The water disperses at high pressure through channels in the cutting blades (7d, Figure 7) to two water outlet nozzles situated at each end of the dual purpose rotary cutting blade. The machine may also comprise a tinned roller (2a, Figure 2) or an integral self-propelling rake, de-thatcher or scarifier with tines (3c, Figure 3) with adjustments (4a, Figure 4) and may comprise an integral wheel driven pump unit enabling the application of liquid fertiliser, weed killer and moss killer formulas.

Description

Grass care and ground surface maintenance machine.

This invention relates to a Multi-Function single unit grass care and ground surface maintenance machine. An all encompassing embodiment comprising a self propelling rotary lawn mower with a dual purpose rotary cutting blade, the design and construction of which integrally includes internal water chambers or as the case may be channels within the embodiment to collect water and simultaneously pressurise same via an integral extended circular or tubular column rising from the centre point where therein is an internal and permanently fixed impeller and further thereto disperse water at high pressure from within same through two high pressure water outlet nozzles situated at each end of the dual purpose rotary cutting blade. Further there is an integral self propelling rake, de-thatcher and scarifier and further there is an integral wheel driven pump unit enabling the application of liquid fertiliser, weed killer and moss killer formulas.

The proposed invention addresses a number of both economic and functional issues faced by gardeners and property owners maintaining their lawns and or grass areas in addition to the cleaning of hard surfaces such as inter alia pathways, drives and patios or other hard standings.

Whilst gardeners have access to various types of Lawn Mower namely a Cylinder Mower type or a Rotary Mower type, with each type available using either Electricity and Internal Combustion Engine as a power source. Yet in all cases, irrespective of type used or chosen, both types have a singular purpose and singular function, namely simply cutting grass.

However, when maintaining a lawn or grass area there is much more to do than just cutting the Lawn or grass area. Grass areas and Lawns require regular raking and further they require seasonal scarifying and timely feeding routines. Faced with these essential tasks, in particular raking and or scarifying, gardeners and property owners have two operational options, the first is the use of a spring tined rake and a laborious intense hand raking of the grass area. The second option is the requirement, purchase or use of a second machine, a scarifier or motorised rake, same is separately costly and has only a singular purpose and sole function, which is to rake the grass area. Now we focus on the task of timely feeding routines to the grass area, and or weeding or moss killing of same. Here again the gardener currently has a number of separate options available in order to conduct such tasks. The first represent traditional hand casting of dry granule fertiliser or using a calibrated granule feed spreader. The modem alternative is the application of liquid feed or fertiliser same requires the use of a hand held sprayer, knapsack sprayer or a wheeled pump sprayer, here again the requirement of an expensive third additional machine, and here again such a machine has only one singular purpose and sole function of applying liquid feed or weed and moss killer. The current proposed invention has been developed to accommodate and encompass the provision of all five primary Grass Care purposes and functions, namely grass cutting, raking, de-thatching, scarifying and feeding, with a sixth function, namely hard surface cleaning, explained as follows.

Further thereto both gardeners and property owners are faced with the task of maintaining the cleanliness and weed and moss free condition of hard surfaces situated within their property, such as inter alia hard surface paths, driveways and patios etc., requiring the removal of dirt, grime, stains and moss growth and infestation. Both gardeners and property owners have a number of options available to them in order to tackle such tasks by separate means, for instance a hard bristle broom and water hose together with a garden hoe, or more conveniently a high pressure hose machine. The later represents yet a fourth machine requirement, which again in this instance is costly and here again such a machine has only one singular pinpose and function, namely the cleaning of hard surfaces.

2.

To that end, and to address and overcome the economic and operational issues faced by gardeners and property owners with regard to the requirements of costly additional machinery and equipment in order to efficiently and conveniently perform such various task requirements related to optimum grass care and ground surface maintenance, the current invention proposes a multi function all encompassing embodiment consisting a self propelled rotary grass cutter aka a rotary lawn mower with a dual purpose rotary cutting blade, the design and construction of which integrally includes internal water chambers or as the case may be channels within the embodiment to collect water and simultaneously pressurise same via an integral extended circular or tubular column rising from the centre point where therein is an internal and permanently fixed impeller and further thereto disperse water at high pressure from within same through two high pressure water outlet nozzles situated at each end of the dual purpose rotary cutting blade. Further there is an integral combined rake, de-thatcher and scarifier, and further there is an integral pumping unit providing the precise and accurate application of liquid fertilizer, weed and moss killer.

The proposed invention will now be described by reference to the accompanying drawings.
