A striper arrangement (200) for striping a lawn (1) configured to be arranged on a robotic work tool (100). The striper arrangement (200) comprises a striper mat (10) and a holding arrangement (300) for holding the striper mat (10) in contact with a N surface of a lawn (1) and is configured such that the striper mat (10) is movable in upwards and downwards direction; and further configured to bias the striper mat (10) in downwards direction by a biasing force (BF), such that movement of the striper mat (10) in upwards direction is restricted until a counter force (CF) exerted by the striper mat (10) onto the holding arrangement (300) exceeds the biasing force (BF). The counterforce (CF) is the force exerted by the striper mat (10) onto the holding arrangement (300) when the striper mat (10) transits from a convex bent shape to a concave bent shape or vice versa. A robotic work tool 100 comprising a striper arrangement (200) for striping a lawn (1).

A system and method for automated lawn chemical treatment application are described. The system comprises a station having a series of concentrated chemicals capable of being mixed and diluted in a reservoir having a water supply to form a specialty formula and a craft which receives the specialty formula for dispersal. Various features of the craft enable a systematic treatment of various plants and/or areas of a law to reduce or eliminate the growth of unwanted plants while promoting the growth of desired plants. These may include the addition of imaging sensors and artificial intelligence to recognize unwanted plants versus desirable plants and develop means to inhibit or grow each over a specified period. A homeowner's ability to consistently treat plants with low-volumes of chemical treatments is enhanced, thus limiting environmental effects and reducing chemical waste.

A ground surface treatment vehicle and systems and methods using the same. In some embodiments, the vehicle may be adapted to autonomously or semi-autonomously identify and optionally treat target areas such as divots on turf surfaces. The vehicle may identify the target area via onboard or remote sensors and autonomously treat the target area by providing a treating material such as infill, seed, particulate matter, and liquids.

This invention is directed to a turf grooming deck configured for attachment to a lawn tractor and includes a deck member positioned between front and rear wheels of the lawn tractor and having an upper platform and a plurality of downwardly depending surfaces that, together, defines an interior area. A plurality of channels is mounted to a bottom surface of the upper platform and arranged in a diamond configuration. Further, the sidewalls define channel openings by which the channels are accessed. The turf grooming deck includes first and second brush modules, each brush module including a plurality of brush members, a first module including a plurality of metal tines and the second module including a plurality of push broom type bristles. The brush modules are interchangeable by insertion or removal thereof relative to respective channels via respective channel openings.

An apparatus for applying a desired amount of mechanical abrasion to plants and selective cutting of undesirable plant material. The apparatus includes a base, a brush and an elevation device for maintaining the base at desirable height. The base has a first longitudinal axis and a plurality of grooves, the grooves being oriented approximately perpendicular to the first longitudinal axis. The brush has a second longitudinal axis and a plurality of bristles and/or blades extending outwardly from the second longitudinal axis. The brush is attached to the apparatus such that the second longitudinal axis is substantially parallel to the first longitudinal axis and the brush is rotatable about the second longitudinal axis. The brush is spaced from the base such that the plurality of bristles engage the plurality of grooves. The base is adjustable enabling the operator to move the base closer or further from the rotating brush/blades.
