摘要： 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.

摘要： 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.

摘要： 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 pressurized air stream conveys seeds through each seed tube and a seed supply supplies seeds to each singulating meter. 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.

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 harrow implement comprises a tool bar and harrow sections extending rearward therefrom. Each of a plurality of hydraulic cylinders is connected between the tool bar and a corresponding harrow section. A hydraulic control is operative to supply pressurized hydraulic fluid such that the hydraulic cylinders exert a substantially constant selected bias force on the harrow sections. The hydraulic control is operative to direct pressurized hydraulic fluid into a first port on each hydraulic cylinder to exert a downward bias force on the plurality of harrow sections, and operative to direct pressurized hydraulic fluid into a second port on each hydraulic cylinder to exert an upward bias force on the plurality of harrow sections. The hydraulic cylinder can be configured to raise the harrow sections to an idle position above the ground, and to a transport position extending up from the tool bar.

摘要： An air seeder apparatus has a frame and a plurality of furrow opener assemblies spaced across a width of the frame at a narrow row spacing, and a plurality of bulk product containers and a bulk meter mounted on each, one of which dispenses seeds through a distribution network to a seed tube on each furrow opener assembly. A plurality of singulating meter is provided, each dispensing singulated seeds to the furrow opener on one of the furrow opener assemblies. During singulating operation seeds are delivered to the singulating furrow opener assemblies only by the singulating seed meter, and during conventional operation seeds are delivered to the singulating furrow opener assemblies only by the bulk meter. A lift system, when in a singulating mode, maintains idle conventional furrow opener assemblies in the transport position while moving singulating furrow opener assemblies between the operating position and the transport position.

摘要： Each wing of a rear folding implement has a wing frame supported on rear wheels for movement along the ground, and a forewing frame and wheel pivotally attached to the wing frame. A center ball joint pivotally connects right and left inner wings and a center wheel assembly supports the center ball joint. The wings extend laterally and the forewing frames are in a lowered position supported on their wheels when in the operating position. To move the wings into a transport position, the implement is towed forward and the wings pivot about the center ball joint to trail rearward and the forewing frames are moved upward to narrow the implement for transport. An air seeder cart hitch is rearward of and near the center ball joint in the operating position, and when the wings trail rearward the cart hitch is near rear ends of the trailing wings.
