Abstract: A mini-hopper for an agricultural row unit that has a fill tube supplying material to a hopper. A backflow preventer is disposed in the fill tube or in a line to the inlet to prevent flow of material from the mini-hopper through the fill tube when the mini-hopper is in a transport position.

Abstract: Air seeders that have force actuators acting on the firming implement and/or the closing wheel to adjust the downforce. In one example, the seeding implement includes a support arm having first and second portions. A finning implement support arm is pivotally connected to the support arm second portion at a first pivot at a first end of the finning implement support arm. A firming implement force actuator is pivotally connected to the support arm second portion at a first end of the firming implement force actuator and connected to the firming implement support arm at the second end of the firming implement force actuator.

Abstract: An air-boom spreader has a hopper for containing particulate material, a metering device having a plurality of sluices, a plurality of outlets transversely spaced-apart on a boom in a direction perpendicular to the direction of travel of the spreader, and a plurality of air lines connecting the plurality of sluices to the plurality of outlets for conveying the particulate material in an air stream from the plurality of sluices to the plurality of outlets. The spreader has more than twice as many outlets as sluices, and the plurality of outlets has an innermost outlet, an outermost outlet and at least three other outlets between the innermost outlet and the outermost outlet whereby each of the innermost outlet and the outermost outlet are supplied with half as much of the particulate material as each of the at least three other outlets.

Abstract: An apparatus for separating grains of seed or fertilizer includes a separating device having a housing with a housing base for mounting on an agricultural machine. A releasable housing cover is arranged on the housing base in a releasable manner. A grain sump receives the grains introduced into the housing interior to be separated out. A rotatable separating disc having openings is positioned in the housing interior. An overpressure region is formable in the housing cover on a front side of the separating disc during operation, such that a flow can form from the overpressure region through the openings to the rear side of the disc and grains separated can be localized near the openings. A grain transfer device includes a feed, a wall bushing and an outlet, wherein the separated grains can be introduced through the feed into the bushing and discharged from the housing interior through the bushing.

Abstract: A trench detection system for an agricultural implement includes a row unit configured to form a trench in soil, to deposit an agricultural product in the trench, and to at least partially close the trench after deposition of the agricultural product. The trench detection system also includes a tactile probe assembly behind the row unit that, in operation, contacts the soil after closure of the trench and generates a signal indicative of a quality of the closure.

Abstract: A purging system for a multiple variety seed meter of a multi-variety planter. The purging system includes seed return valves that may be arranged for receiving seed that was removed from the seed meter. The seed return valves return the removed seed into corresponding appropriate seed storage compartments to allow a new seed variety to be delivered to the seed meter while reducing seed variety mixing in the seed meter. A pipe with a purge passage may extend from the seed meter to a purging hose that delivers the removed seed to the seed return valve(s). Each seed return valve may be a vacuum-actuated piston airlock valve assembly with a valve plunger that reciprocates to define seed collecting and releasing states of the valve.

Abstract: Agricultural implement assembly, for the rapid transformation of a seed drill with a drilling or dragging dosing device, volumetric supplier to an on-demand supplier and vice versa, including at least one hopper containing a granular input, such as grains, seeds or granules of agrochemicals, and a delivery device arranged under the hopper. This device has a structure consisting of two physically delimited areas. A seed box is formed by side walls that delimit its width, a bottom wall, a rear wall with the air inlet from the fan, and a front partition that has at least the passage of the seed to the area where the dragging rotor is eventually located for the case of drilling work, or to the area where the containment slope is located for the case of on-demand supply.
