Abstract: Tine assemblies (100a, 100b, 104) are secured by a single bolt (126) extending diametrically through each tine (120) located in a cavity (112) of a tine plate (110). An outer tine assembly (104) is connected to a sleeve (116) rotatably mounted on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

Abstract: A sand dispenser for a scarifier wherein the sand dispenser is mounted on the scarifier and comprises: a sand hopper having an outlet at a lower end of the hopper; a gate located below the outlet and moveable between an open position and a closed position for controlling the flow of sand through the hopper and into a distributor, the distributor including a row of distributing lines through which sand is directed to flow and enter grooves in the ground created by blades of the scarifier, wherein each distributing line is aligned with a groove.

Abstract: Method and apparatus for dispensing aggregates for lawn improvement. Aggregates are delivered to the site in a primary dispensing vehicle, which is configured to allow a smaller secondary dispensing vehicle to be loaded with the aggregate directly from the primary vehicle. The process includes aerating the soil, distributing a variety of soil amendments evenly over the area to be treated and then dragging a unique drag mat over the area to make a smooth contour and to even the distribution of the aggregate.

Abstract: A tensioning device for traction device, particularly chains, comprises an element, particularly a tension shoe (1) that tensions the traction device. The tension shoe (1) is mounted on a pivot axle (2) for pivoting relative to a base element (3), and a spring element (4) acting between the tension shoe (1) and the base element (3) urges the tension shoe (1) against the traction device. To simplify the assembly of the tension shoe (1) and the base element (3), it is proposed that one of the elements (1, 3) comprises at least one mounting eye (6, 11) having a radial mounting aperture (7, 12) for radially receiving the pivot axle (2) arranged on the respective other element (1, 3).

Abstract: A modular dethatcher and seeder includes a housing having a rear opening, a removable rear cover substantially closing the rear opening, and a plurality of tines driven by a motor to rotate about a shaft within the housing. When the device is to be used as a seeder, a seeder attachment is inserted into the rear opening of the housing in place of the rear cover. The seeder attachment can be driven by the rear wheels of the device. Alternatively, when the device is to be used as a dethatcher, a chute can be removably attached to the rear opening and a collection bag is then attached to the chute to hold debris thrown by the tines.

Abstract: The invention relates to a spreader for use on a delivery tube of a seeding tool. The spreader is mounted for adjustable positioning in the product stream providing a selectable width of product scatter. The invention preferably includes a tapered deflecting surface with a convex laterally angled surfaces for achieving an even scatter pattern, especially over the varying scatter widths. The deflecting surface is pivoted or advanced into the product stream to change the breadth of surface struck by the product as a result causing different scatter patterns. In a preferred embodiment the spreader includes a channel for mounting onto the delivery tube with a pivot pin pivotally securing it adjacent the outlet and selectively adjustable securing points for angular adjustment. The spreading deflecting surface is separated from the outlet in the direction of product stream so that deflected product is not shielded by the delivery tube.

Abstract: A tractor-drawn seed sowing apparatus including a seed sower which travels on a ground surface while furrowing with furrow-cutting claw wheels, a power transmitter connected to a tractor so as to transmit a driving force of the tractor to the seed sower, and a coupler which connects the seed sower to the power transmitter, and the coupler is made of vertically and horizontally arranged linkages so that the seed sower can make up-and-down, pitching, rolling and yawing motions on irregular ground surfaces.

Abstract: A nursery cultivating assembly is carried on a modified zero turning radius tractor and includes a cultivating device, a spraying device, and a tank assembly operably interconnected thereon, while providing for trees to be planted closer together.

Abstract: A special cultivating machine, lawn care apparatus and process are provided to properly prepare, efficiently condition, and gently cultivate the soil, turf and lawn in a uniform manner without uprooting, ruining, or damaging existing healthy plants and grass and without substantial thatching. The special cultivating machine, lawn care apparatus and process attain excellent seed and soil contact for virtually all soil compositions, textures, and conditions, and accurately follow the contour of the ground soil, turf, or lawn, regardless of mounds, hills, valleys, irregularities, clumps, and other soil conditions. The cultivating machine and lawn care apparatus has spring biased, rearwardly facing, scratching arms (cultivation fingers) which are reciprocatingly driven by a crankshaft. The crankshaft is smoothly rotated by a chain and sprocket arrangement. Desirably, the crankshaft and scratching arms can be raised or lowered by a height adjustment assembly to vary the depth and angle of soil penetration.
