摘要： To form a furrow for row guidance systems, a shank is mounted on a frame forwardly of a wheel which includes a V-shaped tire. The shank opens the ground and the tire crushes clods and packs the sides of the furrow. Depth bands on each side of the tire shape the edges of the furrow and prevent loose dirt from rolling back into the furrow. When utilized to reform a furrow, the frame is pivotally connected to the implement for rocking about an upright axis to allow the wheel to trail and average out guidance system corrections and driver steering corrections so that the reformed furrow will be more accurate for the next operation.

摘要： A combination wheel shield and ladder for an agricultural vehicle such as a sprayer includes a deformable plastic body with a profile designed to control the path of deflection and to return the body to original shape after deflection. The shield is mounted on a steel framework also designed to help control deflection and assure return to the original shape. A bail limits maximum shield deflection and increases the strength of the framework. A ladder is incorporated into a plastic wheel shield extension A combination handle-step structure located above the wheel and special platform structure located on the drop axle provide convenient access to the operator's station for all adjusted positions of the drop axle.

摘要： Locking structure for a harvester basket having an upper basket portion telescopingly received within a lower basket portion. Channel lock-ups are located at three of the four corners of the basket. Each lock-up includes two channels, one channel having a length equal to the extension length of the upper basket portion and the other half that length. The two channels are connected together by a pivot pin in the middle of the long channel. One end of the long channel is connected by a pivot pin to the basket and one end of the short channel is connected by a pivot pin to the top of the upper basket portion. As the upper basket portion is raised or lowered, the channels pivot about the middle of the long channel. Approaching the raised position, the upper portion of the long channel may be used as a lever to urge the upper basket to the final extended position. The upper channel portion is received against the upper portion of the short channel, and a quick-lock pin is inserted through the upper ends of the channels adjacent the upper edge of the basket to secure the basket in the telescoped position.

摘要翻译： 收纳篮的锁定结构具有可伸缩地容纳在下篮部分内的上篮部分。 频道锁定位于篮子四个角落的三个角落。 每个锁定包括两个通道，一个通道的长度等于上部筐部分的延伸长度，另一半的长度。 两个通道在长通道的中间通过枢轴销连接在一起。 长通道的一端通过枢轴销连接到篮子，短通道的一端通过枢轴销连接到上篮部分的顶部。 当上筐部分被升高或降低时，通道围绕长通道的中间枢转。 接近上升位置，长通道的上部可以用作杠杆，以将上筐推动到最终延伸位置。 上通道部分抵靠短通道的上部容纳，并且快速锁销穿过与篮筐的上边缘相邻的通道的上端插入以将筐固定在伸缩位置。

摘要： A depth sensing skid arrangement for an implement including a spring steel depth skid connected to a shank which in turn is pivotally connected to a shank support bracket including a spring trip arrangement which permits backing of the implement without damage to the skid or shank. The shank support bracket in turn is connected to a transverse beam operably connected to valve control structure for operating a hydraulic cylinder to maintain a preselected depth of penetration of earth-working tools mounted on the frame. To provide an averaging effect, two resilient depth skids are transversely spaced on the beam.
