摘要： A more robust attachment member or pin is provided for use with farm implements that are attached to a farm vehicle by a quick hitch adapter. The attachment member includes an elongated member having a length and extending between a first end and a second end; and at least three surfaces extending longitudinally along a substantial portion of the elongated member between the first and second ends, the at least three surfaces having at least two different radii. Two of the surfaces are either generally flat or have a very large radius. Two other surfaces, disposed between the generally flat surfaces, have a smaller radius and the two other surfaces may have the same or different radii.

摘要： A ground engagement tool, such as a universal coulter, with an integrated offset to facilitate multiple mounting configurations. In some embodiments, the ground engagement tool includes a polygonal shank, defining, for example, an octagonal or hexagonal cross-section. The polygonal shank enables rotational offset to be secured in discrete rotational orientations. A lower bracket is mounted to a spindle, providing an angular displacement range for angular deflection of the ground engagement tool. The spindle includes a key structure that complements the angular orientations of the polygonal shank so that the lower bracket can be compensated for the rotational offset. A rotational indexing plate enables selection of one of a plurality of angular displacement ranges. Retention rods may be implemented for setting a depth of the tool. A dirt deflector may also be provided, dimensioned to prevent spewing dirt from landing on adjacent plant rows and to prevent fouling in muddy conditions.

摘要： A towed vehicle hitch tongue includes movably connected front and rear tongue members, and a fully exposed master cylinder connected at opposite ends thereof to the tongue members such that a rearward force urging the front tongue member toward the rear tongue member forces pressurized braking fluid out of a port thereof into a braking circuit configured to exert a braking force. The braking circuit prevents braking until the rearward force warrants braking, provides dampening of the brake action, allows the towed vehicle to reverse, and can provide emergency stopping and dampening of movement of the hitch tongue. Instead of using movable front and rear tongue members, sensors can detect what the towed vehicle is doing, and apply appropriate braking force in response.

摘要： A locking mechanism for joining an elongate member to an assembly may include a frame, clamp, actuator and link between the clamp and actuator. Stop surfaces on the clamp and actuator cooperate to secure the elongate member. A pin and the force transmitted by a compression spring may further be provided for additional security. The link between the clamp and actuator retracts the clamp permitting the elongate member to be detached from the assembly. A linear actuator may be operatively disposed between the frame and the actuator for opening and closing the clamp about the elongate member.

摘要： A fastener is disclosed. The fastener includes a housing, a cage, one or more retaining members, and a plunger. The housing defines a housing cavity. The housing cavity includes a recess. The cage is disposed at least partially in the housing cavity. The cage includes a cage cavity and one or more passages in the cage aligned with the recess. The one or more retaining members are retained within the one or more passages. The plunger is movable in the ball cage cavity between a first position to cause the one or more balls to be displaced outwardly relative the one or more passages to seat the one or more retaining members in the recess thereby mechanically locking the housing to the ball cage, and a second position thereby allowing the one or more retaining members to be displaced radially inwardly relative the one or more passages to cause the one or more retaining members to be unseated from the recess.
