    摘要： A distribution tower comprising an upright conduit for pneumatically conveying particulate material in a primary stream. The tower additionally includes a distribution head at the upper end of the conduit, with the distribution head comprising a plenum chamber for receiving the primary stream of particulate material from the conduit. The distribution head further comprises a plurality of discharge outlets for directing particulate material out of the plenum chamber by splitting the primary stream into a plurality of secondary streams. Each of the secondary streams is discharged from the distribution head via one of the discharge outlets. The tower additionally includes a flow adjustment system configured to adjust a distribution of particulate material between the secondary streams without completely restricting the flow of any of the secondary streams through their respective discharge outlet. The tower further includes a control system for controlling operation of said flow adjustment system.

    摘要： A control system for a tillage implement broadly includes front and rear sensors, a leveling assembly, and a controller. The front sensor is positioned on a front of a central section, wherein the front sensor is configured to obtain height information indicative of a height of the front of the central section above a ground. The rear sensor is positioned on a rear of the central section, wherein the rear sensor is configured to obtain height information indicative of a height of the rear of the central section above the ground. The leveling assembly is configured to adjust a front to rear orientation of the central section. The controller is configured to receive the height information from the front sensor and the height information from the rear sensor, and to provide instructions to the leveling assembly to adjust the front to rear orientation of the central section based on the received height information.

    摘要： A depth-adjustment assembly for ground openers of an agricultural implement. The ground openers each include an opening disc, a gauge wheel, and a support assembly securing the ground opener to the agricultural implement. The support assembly is configured to raise and lower the ground opener with respect to the ground and/or to adjust a down-pressure of the ground opener. The depth-adjustment assembly comprises for each of the ground openers, a linkage assembly and a depth-adjustment arm configured to adjust a relative position between the opening disc and the gauge wheel. At least a portion of the linkage extends in parallel relationship with the support assembly. The depth-adjustment assembly further comprises a laterally-extending common pivot bar. Each linkage assembly is secured to the common pivot bar, such that rotation of said common pivot bar is configured to simultaneously adjust the relative position between the opening disc and the gauge wheel of each of the ground openers.

    摘要： A ground-opening apparatus for an agricultural implement. The ground-opening apparatus comprises an opening disc for excavating a furrow in the ground, and a support assembly securing the opening disc to the agricultural implement. The support assembly comprises an upper bar, a lower bar, a forward bar, and a rearward bar. The upper bar and the lower bar extend generally in parallel relationship. The lower bar and the rearward bar are joined at a lower, rearward joint. A rotational axis of the opening disc extends through the lower, rearward joint of the support assembly.
