| 89 | SOWING DEVICE FOR LAWNS | PCT/NL2007000257 | 2007-10-10 | WO2008063050A8 | 2008-09-04 | REINCKE MARINUS |
| The invention pertains to a device for sowing new grass seed, fertilizer or other products in an existing lawn. The device comprises a chassis (1) which includes a drive shaft (15) in the horizontal plane fitted with cams, around which bearing-mounted pin disk (12) combinations have been fitted. The device is also fitted with a seed dosing system, consisting of a seed tray (3) and a driven dosing roll (5), the dose of which can be changed. The dosed seed (4) falls onto a guiding plate (10) along its full width, where the seed (4) is distributed in rows by means of funnel plates (11) and is introduced to the pin disks (12). The pin disks collect the seed and plant it in the existing lawn. In order to improve results on hard soil, a vibrating action in the vertical plane can be added to the pin disks (12) by driving the central drive shaft (15). This vibrating movement pushes the seed into the soil, presses it against the side of the hole and improves penetration of the pins in hard soil. | ||||||

| The present invention is directed in part to grass seed mixtures for low maintenance lawns and uses thereof. Lawns established from seeds blended in certain proportions as described in the disclosure have a slow growth rate and deep roots and grow well in many regions around the world. Because these lawns require little watering or fertilizer, and can be hardy and naturally insect-tolerant, they are safe and environmentally friendly. | ||||||

| 93 | MODULAR DETHATCHER AND SEEDER | PCT/US0041793 | 2000-11-02 | WO0131992A2 | 2001-05-10 | MORAN RICHARD TADASHI; BIEGEL EDWARD T |
| A modular dethatcher and seeder includes a housing (10) having a rear opening, a removable rear cover (12) substantially closing the rear opening, and a plurality of tines (40) driven by a motor (11) to rotate about a shaft within the housing (10). When the device is to be used as a seeder, a seeder attachment (20) is inserted into the rear opening of the housing (10) in place of the rear cover (12). The seeder attachment (20) can be driven by the rear wheels (13) of the device. Alternatively, when the device is to be used as a dethatcher, a chute (50) can be removably attached to the rear opening and a collection bag (55) is then attached to the chute (50) to hold debris thrown by the tines (40). | ||||||
