  • Patent number: 8590632
    Abstract: A single pass ground driven tiller and seeder apparatus includes a support frame, an elongated drive rotor journaled transversely on the frame, a tillage assembly pivotally connected to the frame and formed by a pair of rearwardly extending bearing plates and having an elongated tillage rotor journaled thereto and extending transversely therebetween, and a firming roller journaled between mounting plates pivotally connected to the bearing plates. The drive rotor is rotated by ground contact as the apparatus is drawn along by a tractor. The drive rotor is drivingly engaged with the tillage rotor so that the tillage rotor rotates at a faster speed than the drive rotor. A seed metering mechanism is supported on the frame and deposits seed in front of the drive rotor. The tillage rotor breaks the soil and incorporates the seed into the soil, after which the firming roller firms the seed bed.

  • Patent number: 7308946
    Abstract: A travelling rolling digger (1) for sequential hole drilling or for producing sequential cultivated spots in soil. The travelling rolling digger (1) includes at least one drilling shaft which is rotatable by a drive mechanism about a longitudinal shaft axis and has a rotating soil penetrating edge. The drilling shaft is mounted to roll about a horizontal shaft in a soil penetrating plane while the horizontal shaft moves in a direction of travel of the traveling rolling digger. The rotating drilling shaft enters the soil at an entry angle and digs into the soil while the horizontal shaft moves in the direction of travel and the drilling shaft continuously changes its angle relative to the soil from the entry angle to a vertical position. The traveling rolling digger further comprising at least one cleaning blade (6).

  • Patent number: 7234535
    Abstract: A novel drill for the aerification of turf grasses is disclosed. The drill comprises a chuck and a fluted turf drill bit held by the chuck. The chuck includes a locking mechanism which permits the chuck to rotate freely about its longitudinal axis when loaded in compression (as when the drill is inserted into the ground) but which locks, preventing rotation, when the drill is loaded in tension (such as when the drill is withdrawn from the soil). The drill bit has a smooth upper section and a fluted lower section. The smooth section decreases the probability of entangling the turf in the drill bit with subsequent lifting of the turf when the drill is withdrawn. The tip of the drill bit is adapted to provide a torque to the drill bit during insertion into the ground. Thus, the bit spirals into the ground upon insertion, but locks upon removal, thereby permitting the flutes of the bit to cut a cylindrical hole in the ground while removing soil from the hole by retaining it in the space between the flutes.

  • Patent number: 4224997
    Abstract: A soil cultivating implement has an elongated frame portion and a plurality of rotatable members mounted at the lower ends of respective elongated shafts. Each member includes a carrier and tools on radial arms are connected to the carrier. The carrier is fastened to a nonrotatable tube through a hood and flange arrangement that prevents stalks and the like from fouling the shaft housed within the tube. The tools can be rigid tines or resilient strip-like blades which are angled downwardly in the direction of rotation. Guides in the form of rods can be mounted to coextend with the tools, upwardly to the rear so that soil loosened by the tools is displaced upwardly by forces that crumble the displaced soil before the latter falls rearwardly. Drive to shafts is effected through a gear box on the frame portion and further shafts that have pinions in mesh with those on the soil working member shafts. A further implement can be linked to the frame portion and driven via a rear shaft of the gear box.

    Abstract: An implement assembly includes two elongated frame portions with respective coupling members that are linked to one another. Either frame portion can be leading or trailing and in a preferred arrangement, the leading frame portion has tined soil working members that work overlapping strips of top soil while the trailing frame portion has tined tools that work subsoil in non-overlapping paths. A common transmission can be fixed to either respective gear box that rotates the members and the tools. In either arrangment, the transmission is connected to the driving gears for both the members and the tools which can be rotated at different speeds from that of the members. A ground engaging wheel can be positioned at either side of the center of the assembly to bear on ground that is located between neighboring tools and/or members. The member can work paths of soil having different widths from those of the tools.

  • Patent number: 4117312
    Abstract: An electrical heating cable which limits power output once an established temperature limit is reached. The cable includes a high-resistance element and a temperature-sensitive variable resistance element electrically connected in series between two electrical conductors otherwise insulated from each other by insulating material. The temperature-sensitive resistance undergoes a substantial positive increase in resistivity when the temperature of the cable nears the established temperature limit. The increase in resistivity substantially reduces the heat-generating current flowing in the cable to limit the power output.

  • Patent number: 4051902
    Abstract: A cultivating implement has one or more forward cultivating rotors that are driven to work the top soil. During this working, stones and debris are unearthed. At the rear of the cultivating members, one or more rows of soil working members are moved through the soil and these members are soil engaging members with edges that contact the stones and push the stones down into the subsoil. The soil engaging members can be discs with edges having projections and the discs can be driven to rotate in the same or opposite direction as the rotor. Alternatively, the soil engaging members can be bars that extend down into the soil. In either case, a sieve of rods or bars can be positioned behind the rotor to allow fine soil to pass while stones are guided downwardly in front of the fine soil. The lower ends of the soil engaging members can be interconnected with a horizontal shaft on which the discs are mounted. A protective hood overlies the rotor as well as the soil engaging discs or bars.

    Abstract: A cultivating machine has one or more working members that are driven to rotate about upwardly extending axes. Each working member is connected to a drive transmission to turn and, spaced apart soil working members mounted for free rotation about respective axes, are moved through the soil. At least two of the soil working members are different from one another and capable of workingthe soil in different ways. One member can be a group of tines that are freely rotatable about an upwardly extending axis and an adjacent member can be a disc that rotates about a horizontal axis. Each member includes a stub shaft that is journalled in a universal mount so that the members can be released and exchanged to meet varying soil conditions. The mount has a pivot connection and a setting device to retain the soil working member at various working angles. Also, the stud shaft is adjustable within a sleeve of the mount.

    Abstract: An agricultural implement combination has a forward cultivator with soil working blades that rotate about a horizontal axis extending transverse to the direction of travel and a rear harrow having tined soil working members that rotate about upwardly extending shafts positioned in a row also extending transverse to the direction of travel. The cultivator and harrow each have a coupling member and their coupling members are linked by pairs of arms that cross one another when the implement is viewed from the side. A driving system includes a separate transmisson with change speed gearing for the cultivator and the harrow and the input shaft of the cultivator is connectable to a prime mover p.t.o. A telescope shaft connection bridges the two transmissions so that the blades of the cultivator and the tined members of the harrow can be driven from a single p.t.o. The harrow preferably has a supporting roller at the rear to smooth the soil worked first by the cultivator and then by the harrow.
