| 221 | STRUCTURE FOR CONVERTING AN INTEGRAL IMPLEMENT TO A DRAWN TYPE | US10298619 | 2002-11-15 | US20040094313A1 | 2004-05-20 | Brian E. Myers |
| Attachment structure for converting an integral implement to a pull-type implement includes wheel modules which can be placed at different locations along the frame to avoid interference with tool standards or other hardware. Each module includes both a forward gauge wheel and a rearward transport wheel. The transport wheels are located behind the center of gravity of the implement for stability, and the forwardly located gauge wheels offset the moment resulting from standard draft. A hitch storage jack doubles as a gauge wheel adjustment tool. To maintain the wheels in phase and provide a transport lock-up feature, a simple parallel circuit with pilot operated check valves on the base or lift end of each cylinder is utilized. | ||||||

| 235 | Headline stop for agricultural planter | US437757 | 1999-11-10 | US6131669A | 2000-10-17 | Terrance A. Friggstad; David R. Hundeby |
| An agricultural planter is provided with hydraulically operated devices to effect the folding and unfolding of the planter support structure between operative and transport configurations. The planter includes a laterally extending tool bar that is pivoted about a transverse axis to forwardly roll the tool bar between a lowered field operating position and a raised transport position. The transverse pivot axis is located such that the first component of the pivotal movement of the tool bar from the field operating position is generally vertical, while a second component of the pivotal movement of the tool bar approaching the transport position is generally horizontal and forwardly of the first component. The headland position corresponds to a position in which the tool bar is raised sufficiently to move the planting units mounted thereon out of the ground to facilitate the turning of the implement at the end of the field. A sensor senses the positioning of the tool bar at the headland position and activates a valve in the hydraulic circuit to stop the operation of the tool bar actuators pivotally rotating the tool bar. A bypass, in the form of a solenoid that when selectively energized will override the signal of the sensor, selectively permits the tool bar to be raised the entire way to the transport position. | ||||||
