Abstract: An seeder includes a frame on ground wheels defining tool bars for seeding elements spaced across the frame. Each element includes a pair of parallel arms connected to the tool bar bracket forming a parallel linkage for up and down movement of a support arm connected at a rear end and carrying the packer wheel. A spring applies a downward spring force on the parallel linkage to apply a downward force on the packer wheel so that the spring force increases as the parallel arms pivot upwardly and decreases as the parallel arms pivot downwardly. A control device is arranged to raise and lower the tool bar in response to a detected value of a sensor so as to change the angle of the parallel linkage and change the spring force. A cam controlled double rack adjustment of the height of the opener allows the user to change seeding depth.

Abstract: A furrow opener apparatus attachable to an implement has a trailing arm with a packer wheel at the rear end, and a furrow opener attached forward of the packer wheel. An actuator moves the trailing arm between a lowered operating position and a raised transport position. A latch mechanism engages the implement frame and the trailing arm when the actuator is operated to move the trailing arm to the transport position, preventing the trailing arm from moving downward. A release mechanism moves the latch mechanism to an unlatched position when the actuator is operated to move the trailing arm from the raised transport position to the lowered operating position, allowing the trailing arm to move down from the transport position.

Each drill in a set of drills is a separate unit which is mounted on a vehicle. Each unit includes a split press wheel with an opener mounted within the wheel. The units can easily be individually mounted or adjusted on the vehicle for spacing and height. The opener has an articulating adjusting arm which allows easy adjustment to all preferred positions.

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.

Abstract: A trip assembly for a ground-working implement includes a rigid toggle member and a spring toggle member that are pinned, respectively, at a first point to a ground-engaging tool and at a second point to a frame. The rigid toggle member and the spring toggle member are pinned together at a third point that is a small distance vertically below a line extending between the first two points. A fulcrum from the rigid toggle member is in contact with the top of the spring toggle member at a central position. An obstruction force transmitted to the ground-engaging tool is transmitted to flex the spring toggle member vertically upwardly at the central position. As the spring toggle member flexes vertically upwardly, the third point moves upwardly through the small distance. Once the third point crosses the line between the first two points, the trip assembly trips and moves the ground-engaging tool to a vertically upwardly removed tripped position.

Abstract: A seed drill including depending furrow openers having a lower shovel and a supporting seed boot. Each seed boot is pivotally supported on a longitudinal drag bar assembly connected to it about a transverse pivotal connection. The forwardly extending arm at the upper end of the seed boot selectively engages one end of a longitudinal leaf spring mounted to the drag arm assembly. A preselected planting position for the shovel and seed boot is defined by an overlying adjustable stop. An arcuate abutment surface is interposed between the seed boot arm and leaf spring. A stop is interposed between the drag arm assembly and leaf spring for limiting upward movement of the free spring end.
