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: A multiple variety planter has a direct vacuum system that allows for planting multiple varieties of seed while reducing occurrences of mis-planting events or planting inconsistencies such as multiples and skips by providing highly controllable seed meter vacuum performance characteristics that are controllable on a row-by-row basis. The direct vacuum system may include a vacuum unit at each row unit of the planter to apply a vacuum pressure to a seed meter at the row unit. Each vacuum unit may be individually and variably controlled to apply different vacuum pressures based on which seed variety is being planted with the respective seed meter at a given time.

Abstract: A precision pneumatic seed drill. The seed drill comprises at least one sowing element having a seed selector device housing a perforated selector disc which selects seed and has opposing faces subject to a pressure differential. A sowing duct is associated with the selector device. A system measures the speed of forward movement of the seed drill with reference to the ground being sown in order to vary the rotational speed of the selector disc according to the speed of forward movement measured by the measuring system. A pressurization device associated with the selector disc applies the pressure differential to the faces. An ejector along the sowing duct is fed by a compressed air dispenser for pneumatically accelerating the seeds singled out by the selector device. A device for varying the pressure of compressed air fed to the ejector is calibrated according to the typology of the seed to be sown.

The seed meter may also include a first seed disk rotatable within the housing to convey the first seeds from the first seed chamber, a second seed disk rotatable within the housing to convey the second seeds from the second seed chamber, and a drive assembly configured to simultaneously rotate the first and second seed disks. In addition, the seed meter may include a seed deflector movable relative to the first seed disk and/or the second seed disk to control which of the seed types is discharged from the housing based on a selected seed type to be delivered by the seed meter.

Abstract: An agricultural machine includes a seeding system comprising a plurality of planting units, each planting unit configured to meter and deliver seed and a control system configured to obtain a seed planting model that identifies a plurality of seed planting locations on a worksite, identify a machine path on the worksite, identify, based on the machine path, a set of the seed planting locations for each of the planting units, and control each planting unit to deliver seeds to the set of seed planting locations identified for the planting unit.

Abstract: An open-loop or closed-loop control system for an agricultural utility vehicle includes a distributor linkage for dispensing fertilizer, plant protection agent, or seed, and has a center part and two lateral extension arms connected by joints to the center part with a plurality of linkage sections (4) which can be folded relative to one another in a transport position and folded out relative to each other in a working position. The control system also has at least one sensor and a data processing unit configured such that signals of the sensor are processed so as to generate a control signal for the hydraulic device, and the hydraulic device can be controlled in order to set damping of vibrations occurring on the distributor linkage in a direction of travel.

Abstract: An apparatus, which may be a tillage apparatus, may have a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices.
