Abstract: A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.

Abstract: An inductor apparatus includes an inductor assembly mounted under a seed container such that seeds flow into a reservoir. An air conduit carrying pressurized air extends along the reservoir. Seed channels extend from an inlet located above a pickup air opening in the air conduit to an outlet, and a bypass channel extends downward from each seed channel through an upper wall of the air conduit. A pickup air stream flowing out the pickup air opening forms a seed air stream entrained with seeds flowing into each seed channel inlet and a bypass air stream flows from the air conduit through each bypass channel into each seed channel and the combined seed and bypass air streams flow out the seed channel outlets. The seed channel outlets can be arranged along each side of the inductor assembly, and the rate of flow of the bypass air stream can be adjusted.

Abstract: A seed supply system includes a singulating meter with a seed reservoir pressurized to a meter pressure that is in a desired pressure range. A seed supply air stream carries seeds dispensed from a nurse tank to an air release assembly located above the singulating meter. As seeds are metered from the seed reservoir at a rate less than the rate seeds are dispensed from the nurse tank seeds accumulate in the air release assembly. The pressure of the seed supply air stream at the top of the seed column fluctuates and a barrier is operative to resist air flow between the air release assembly and the seed reservoir sufficiently to maintain the meter pressure in the desired meter pressure range. The barrier can be provided for example by an airlock or a column of seed in a drop tube between the air release assembly and the seed reservoir.

Abstract: 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.

Abstract: A seeding apparatus has a frame and a plurality of furrow openers spaced laterally along the implement frame. A like plurality of singulating meters is provided, each mounted on the frame close to a corresponding furrow opener, and seed tubes are configured to receive singulated seeds from a corresponding singulating meter and deposit the seeds in the furrow created by the corresponding furrow opener.

A meter control operates each singulating meter to provide a variable seeding rate that is independent of the seeding rates of the other singulating meters. A seed catching member follows each furrow opener and catches the seeds exiting the seed tubes to maintain a consistent seed spacing in the furrow.

A furrow opener and a packer wheel are attached to a rear link of the assembly. In operation the furrow opener and the packer wheel are in fixed positions with respect to the rear link member, and a bias element is operative to exert a downward bias force on the furrow opener assembly. A front pivot line connecting the upper and lower front pivot axes is parallel to a rear pivot line connecting the upper and lower rear pivot axes, and the front and rear pivot lines are oriented at a pivot angle with respect to a vertical orientation, and the pivot angle is adjustable to vary a furrow depth of the furrow.
