Abstract: A method and apparatus for producing a plurality of spaced apart cultivated spots in soil. A spot cultivator (1) is moved across the soil in a direction in which the spaced apart cultivated spots are to be formed. The spot cultivator (1) includes at least one tilling shaft (7) which is mounted to roll about a horizontal axis which moves with the spot cultivator (1) and which is rotatable about a longitudinal axis of at least one tilling shaft (7). At least one tilling shaft (7) is rolled about said horizontal axis in a plane which intersects the soil. The at least one tilling shaft (7) has a length sufficient to contact and penetrate the soil at a controlled spacing during each rotation about the horizontal axis.

Abstract: Ground clearing apparatus (10) and a method for transporting the apparatus are provided. The ground clearing apparatus (10) includes a plurality of ground clearing tools (20) attached to a rotating shaft (18). The ground clearing tools include a chain (22) having a plurality of links and a hammer (24) attached to one end of the chain (22). The rotation of the shaft (18) causes the hammer (24) to strike objects in its path and generally mill the ground surface.

Abstract: Equipment for spraying plants and trees with a plant treating liquid injected into turbulent pulsating air streams, including at least one oblong air outlet structure for issuing turbulent pulsating air streams in diverging directions. The air outlet structure has an oblong air inlet opening for receiving pressurized air and includes a plurality of longitudinally arranged air outlets extending outwardly from the air inlet opening. The air outlets each have a respective axis whose angle of inclination differs with respect to an angle of inclination of an adjacent air outlet. At least one spray nozzle is arranged to inject a plant treating liquid into the turbulent pulsating air streams issued from the air outlet structure.

Abstract: Spraying equipment for plants growing in parallel rows comprises a main horizontal air duct and several secondary ducts extending therefrom in downward direction between the rows of plants. Each duct is provided with air outlets directed towards the plants, which are alternately opened and closed by valves so as to eject the air in pulses. One spray nozzle each is positioned in the center of each air outlet serving to eject into the pulsating air stream a jet of spraying fluid which is thereby carried onto the plants covering these from top to bottom. The equipment is attached to the front or rear of a tractor which carries a supply of spraying fluid and a pump serving to supply the material to each nozzle through piping. A blower is positioned in the main duct supplying air under pressure to the secondary ducts and to the air outlets.

Abstract: A surveying and mapping implement indicates the level differences of the ground over which it travels, in relation to the distance travelled. It comprises a carriage consisting of a swivelling front wheel, two center wheels attached to the outside of a U-shaped vertical frame, and two rear wheels connected to the U-shaped frame by means of a thill and a universal joint positioned co-extensive with the axis of the center wheels. The universal joint permits the rear wheels to move up and down and sideways, as well as to twist in relation to the center wheels. The wheel base between the center wheels and the front wheel is identical with that between the center wheels and the rear wheels, in order to facilitate calculations.
