The reassuring sound of lawns being mowed of a summers afternoon may soon become a thing of the past, assuming that the lawns in question are big enough to accommodate Wolf-Garten’s ‘Zero’ mower; a device that cuts grass with a laser beam.
The ‘zero’ is a two-seater ‘lawn care vehicle’ approved for use on public roads with a working width of 150 cm and powered by an engine said to produce practically no emissions due to catalytic afterburning.
Features of the new lawnmower include laser cutting and measuring systems, cameras and sensors to control the vehicle’s operations and Internet/intranet access for groundsmen who need to order supplies on the move.
Additionally, Wolf also state that the mower chops grass clippings into tiny particles and dries them before applying them to the lawn in a jet of air.
Wolf-Garten put the secret of the Zero’s development down to a patented process they call siltidry, which enables the lawnmower to solve several problems at once, including noise pollution, waste disposal, nutrient administration and lawn disease.
Wolf-Garten’s siltidry process is also said to optimise the recycling of cuttings as a natural part of lawn fertilisation. It does so by applying the tiny particles to the lawn and, initially, by dehydrating the clippings. Since grass has an 80 % water content, the drying operation significantly reduces the cuttings’ volume.
The tiny dry particles that fall on the lawn cannot, say Wolf-Garten, give rise to thatch and do not foster lawn diseases. Rather, they form the basis of a supply of nutrients to the grasses that are said to be enhanced by Wolf’s new granular lawn fertiliser.
This fertiliser accelerates composting of the dried grass particles, balances the soil’s nitrate content, and supplies the soil with all the necessary nutrients.
