    Abstract: A two piece seed boot for a seeding machine has a upper cast portion and a lower cast portion. Both the upper and lower portions are provided with aligned seed passages which received metered seed from the seed tube and discharge the metered seed to the planting furrow. The upper cast portion is mounted to the planting unit frame and the seed tube by an integral mounting clevis. The lower cast portion is provided with first and second upward extending mounting lugs. The first mounting lug is received in a recess formed in the upper portion. The second mounting lug engages the planting furrow side of the upper portion. The rear of the upper and lower portions are provided with aligned mounting holes through which a mounting bolt passes securing the lower portion to the upper portion.

    Abstract: An opener for use in varying ground conditions, ranging from no-till to conventional full tillage conditions, includes an adjustable down pressure control and a down pressure spring and tension link assembly which selectively provide a limited free float opener condition or a conventional down pressure spring controlled bias condition. A sleeve slidably received by the opener arm and mounted over the lower portion of the tension link assembly allows the opener to free float in loose soil conditions so that only the weight of the opener provides downward bias when the down pressure control is adjusted to a minimum condition. The opener is free to ride up and down to follow irregularities in the ground surface. In harder soil conditions such as those encountered in no-till farming methods, the down pressure control is adjusted to a position wherein an enlarged portion on the sleeve bottoms against the opener arm and the spring begins to compress so that the opener operates in the conventional spring biased mode. The sleeve allows increased downward movement of the opener to follow depressions in the soil.

    Abstract translation: 用于不同地面条件的开启器，从免耕到常规全耕耕作条件，包括可调节的下压控制和降压弹簧和张紧连杆组件，其选择性地提供有限的自由开启器状态或常规的下压弹簧 受控偏压条件。 由开启臂可滑动地容纳并安装在张紧连杆组件的下部上的套筒允许开启器在松散的土壤条件下自由浮动，使得当下压力控制被调节到最小时，开启器的重量仅提供向下的偏压 条件。 开启者可以自由地上下移动以遵循地面不规则。 在诸如在免耕种植方法中遇到的较难的土壤条件中，将压力控制调整到其中套筒上的扩大部分抵靠开启臂并且弹簧开始压缩的位置，使得开启器以常规操作 弹簧偏置模式。 套筒允许开启者向下移动以跟随土壤中的凹陷。
