  • Ground working paired row furrow opener
    Patent number: 6357368
    Abstract: A ground-engaging paired row furrow forming tool includes a tool body having fore and aft ends with an outer edge defined on each of two opposing sides of the tool body. A furrowing wing is located adjacent each of the opposing sides and protrudes from bottom portions of the tool body. The tool body has lower surfaces including a central front surface portion which is angled upwards towards the fore end and a center passage is defined between the furrowing wings. This passageway is in part defined by a central rear surface portion which is adapted to be substantially aligned fore to aft in a direction of travel T during operation of the ground engaging tool. This paired row opener works well without compromise in a broad range of soil conditions without fouling and enables planting of seed rows spaced widely apart while minimizing soil surface disturbance.

  • Down-pressure system for agricultural implement
    Patent number: 5687798
    Abstract: The implement has a folding tool-bar, with a main section and wings. Hydraulic rams press the wings downwards relative to the main section during operation. Another ram presses the main-section downwards, reacting the force against a relatively weighty component, such as a air-cart. During non-operation, a carriage wheel is lowered, which raises the main section of the tool-bar off the ground. The wings also are raised clear of the ground. A sensor detects the position of the carriage wheel, and blocks movement of the wings downwards when the carriage wheel is lowered.
