  • Publication number: 20110278030
    Abstract: In orchards or fields of grape vines, weeding in inter-plant spaces may be performed with a mechanical weeder. The weeder may include a frame configured to be propelled by a motorized vehicle. A rotatable weeder unit may be pivotally connected to a pivot arm attached to the frame and a spring may be connected to hold the rotatable weeder unit in a nominal pivotal position relative to the frame responsively to a force exerted by the spring. When encountering a producing plant, the weeder unit may deflect away from the plant thereby precluding damage to the plant.

  • Patent number: 4489787
    Abstract: For cutting the roots of weeds in agricultural fields, rolling knives in the form of flat, circular plates with sharp, peripheral edges are journaled to struts connected to a tool bar drafted in a direction of draft. The knives rotate about knife axes that are normal to knife planes containing their sharp edge. All knife axes are about 45.degree. from vertical. For bedded fields, the rolling knives are preferably connected to the tool bar in knife sets of two for each soil bed, with the knives of each set engaging opposite sides of each bed. As the rolling knives roll within the soil, their sharp edges sever the roots of weeds. In an alternate embodiment, a vertical stabilizer plate is rolled opposite each rolling knife to stabilize the soil therebetween. In another embodiment, each strut includes a hinge that has a hinge axis substantially within the knife plane. The knives swing about the hinge axes and trail in the direction of draft following the path of least resistance through the soil.

  • Patent number: 4090571
    Abstract: An implement preferably has elongated, stationary beams that extend horizontally transverse to the normal direction of travel. Staggered soil cultivating rotors are fastened to the beams at spaced apart locations and are ground driven to work closely adjacent strips of soil or a single broad path. Each rotor is freely rotatable about an upwardly extending shaft and has downwardly extending soil working members, such as tines, with lower active portions. Each active portion can have a lower outwardly directed part that, during rotation, describes a circle having a radius about equal to or less than the length of the active portion. The outwardly directed tine part increases ground contact and improves rotation. The rotors can be mounted in pairs; the rotors of each pair being angled from the vertical so that they rotate in opposite directions from one another.

  • Patent number: 4034814
    Abstract: A cultivator or harrow has a row of soil working members and each of these members is a rotatable support on a shaft that is driven to rotate about an upwardly extending axis. Each support is comprised by two similar diametrically opposed portions and each portion has a lower tine and an upper tool that differs in shape and form from the lower tine. The upper tool can be a pair of different tines or a tine-like extension of the support portion that functions as a rigid tine. The lower more resilient tine works the sub-soil and the upper tool works the topsoil. The lower tines of the two portions can be a single element of spring steel that is retained by quick release pins in lower support recesses and the fastening portions of the lower tines can bear on the heads of further pins that retain upper tines in their corresponding recesses so that one release means retains all of the tools on each support portion.
