Abstract: A grass treatment device 801 that comprises a first roller 701 configured to contact a grass surface 802, a second roller 805 configured to contact the grass surface 802, a treatment tool 804 capable of treating the grass surface 804. The grass treatment device 801 further comprises adjustment means 303, 305 configured to allow an adjustment of a distance between the treatment tool 804 and the first roller 701, the adjustment capable of affecting a distance 807 between the tool 804 and the grass surface 802. The adjustment means 303, 305 further comprises graduation means configured to indicate to a user predetermined quantized intervals of the distance 807 between the tool 804 and the grass surface 802.

Abstract: A grass treatment device (100) is provided, which comprises a frame (101), at least one roller (104) mounted to the frame and configured to contact a grass surface and a grass treatment tool (105) mounted to the frame substantially adjacent the roller and configured to treat the grass surface. The grass treatment device (100) comprises a rotating assembly (108) mounted substantially adjacent the roller (104) and having a plurality of bristle members (110), and driving means (114) operably connecting the rotating assembly to the roller. The driving means comprises a gear mechanism having a first driving gear (115) attached to an axis of the roller and a first driven gear (116) attached to an axis of the rotating assembly, whereby motion of the roller (104) is translated to the rotating assembly (108).

Abstract: A grass treatment device height adjustment assembly for adjusting the height of a grass treatment tool above ground level includes a height adjustment mechanism and an elongate rotational element, such as a roller, having first and second ends. The rotational element has an axle extending substantially along the longitudinal axis of the element about which the element rotates. The height adjustment mechanism includes a rotatable member connected to the axle of the rotational element wherein the rotatable member is associated with a second fixed axis of rotation that is substantially parallel to but offset relative to the first rotational axis. The second axis of rotation enables the height adjustment mechanism to adjust the position of the first axis of rotation relative to the second axis of rotation.

Abstract: A grass treatment device comprises: a first grass treatment element disposed towards a front portion of the device; a second grass treatment element disposed towards a rear portion of the device; a third grass treatment element disposed substantially between the first and second grass treatment elements, the third element being in the form of a grass cutting tool; and a fourth grass treatment element connectable at a position substantially between the first grass treatment element and the grass cutting tool, the grass treatment elements being elongate and having their longitudinal axes disposed substantially parallel to each other, the grass treatment device characterized in that the fourth grass treatment element is configured to be displaced from the position located between the first grass treatment element and the grass cutting tool in order to enable the first grass treatment element to substantially occupy the position.
