  • Patent number: 8215247
    Abstract: A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification.

  • Publication number: 20110232552
    Abstract: An opener for depositing fertilizer and seed in a single pass, double-shoot manner includes a rotating disc that cuts a furrow in a planting surface, a fertilizer tube that drops fertilizer into the furrow, and a trailing seed tube assembly, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface onto which seed is deposited. The seed trench provides a seed bed that is offset from the bottom of the furrow to provide horizontal and vertical stratification of the seed and fertilizer.

  • Patent number: 7631817
    Abstract: A lock assembly operable to secure a lift linkage associated with moving a boom assembly between a lowered, operative position and a raised, inoperative position is provided. The lock assembly includes a lock pin mounted at a carrying frame interconnected between a lift linkage and the boom assembly. The lock assembly also includes a lock plate mounted at the lift linkage. In the raised position of the lift linkage, the lock plate includes a slot configured to align so as receive the lock pin. Once aligned, the boom is pivoted toward the folded, stowed position. As the boom pivots, the boom pushes the lock pin through the slot. The lift linkage is then lowered to seat the lock pin in the slot and thereby secure the lift linkage and supported boom in the raised, folded position.

  • Patent number: 7431221
    Abstract: A lock assembly is provided to secure a multi-stage folding boom assembly having left and right booms, each boom having an middle section that pivots about a vertical axis with respect to an inner section, an outer section that pivots about a second vertical axis with respect to the middle section. The lock assembly includes a first interlock portion that receives a second interlock portion when the first section pivots laterally inward about the first vertical axis with respect to the second section to a first stage folded position. As the middle section pivots forward and laterally inward toward a second stage folded position with respect to the third section, the first interlock portion slidably moves and interlocks with the second interlock portion to restrain the outer section from falling out of alignment with respect to the middle section.

  • Patent number: 7429003
    Abstract: An assembly for locking a suspension arrangement operatively connected between a boom assembly and a carrying frame that are supported on a boom support implement or vehicle is provided. The implement or vehicle also includes a lift linkage operable to move the carrying frame and connected boom assembly between a lowered, operative position and a raised, inoperative position. The lock assembly includes a lock pin and a bracket assembly. The lock pin is mounted at the lift linkage. The bracket assembly includes a first bracket and a second bracket. The first bracket is mounted at the boom assembly and the second bracket is mounted at the carrying frame. In the raised, inoperative position of the boom assembly, the first and second brackets are configured to receive the lock pin in a locked position to restrain the boom assembly from swinging or rotating with respect to the lift linkage.

  • Patent number: 7426827
    Abstract: A system for reducing oscillating movement of a boom assembly about a fore-and-aft aligned axis defined by a pivotal connection of a suspension arrangement independent of a carrier frame is provided. The system includes an accumulator, a cylinder actuator mechanically interconnected between the carrier frame and the boom assembly, and a metered orifice connected in fluid communication to restrict a fluid flow between the accumulator and the cylinder actuator. In response to rotation of the boom assembly in a first direction relative to the carrier frame, the system creates a force resisting the rotation of the boom assembly in the first direction. Thereby, the system deadens oscillating pivotal movement of the boom assembly relative to the carrier frame and exerts a biasing force to assist in returning and/or maintaining the boom assembly at a generally horizontal alignment.

  • Patent number: 7395663
    Abstract: A system to lock a roll-suspension arrangement operatively connected to allow pivotal movement of a boom assembly about a fore-and-aft axis independent of a carrier frame is provided. The system includes an actuator cylinder having an end movable in a linear direction relative to a fixed end. The fixed end of the actuator cylinder is connected at the carrier frame, and the movable end is connected at the boom assembly. The system further includes a lock valve located in fluid communication with the actuator cylinder. The lock valve in a closed position prevents a fluid flow therethrough so as to restrain movement of the actuator cylinder and rotation of the boom assembly with respect to the carrier frame. In an open position, the lock valve releases movement of the actuator cylinder so that the boom assembly freely pivots independently of the carrier frame.

  • Patent number: 6343661
    Abstract: A suspension system supports an implement on a work vehicle and includes a linkage mechanism providing pivotal connection between the work vehicle and the implement and adapted to pivot in such manner as to permit relative upward and downward movement between the vehicle and the implement while maintaining a controlled or selected orientation between them. A hydraulic actuator capable of extending and retracting is operatively connected between the work vehicle and the implement so as to effect the pivotal motion of the linkage and relative motion between the vehicle and implement. A shock absorber is interposed between the hydraulic actuator and one of the work vehicle and the implement for absorbing shock loadings tending to pass between the vehicle and the implement via the hydraulic actuator when in use. The shock absorber includes an elongated link mounted for pivotal motion at a point between opposing ends thereof.
