Abstract: A product distribution device shown as an agricultural air seeder in which product distribution can be selective stopped and started in sections of the machine width. The functioning of the section control system is monitored by sensors that directly detect the control member position as opposed to sensing the commanded position of the control member. Likewise, in generating a map of the area covered, the actual detected position of the control member is used instead of the commanded position of the control member. An operator is notified of inconsistencies between the commended position of the control member and the sensed position.

Abstract: A volumetric metering system for metering a product in an agricultural machine includes a roller element, a drive mechanism configured to rotationally drive the roller element to convey the product along a conveyance path to a product receiving component, and a guide element disposed on a side of the roller element. The guide element is configured to guide the product along the conveyance path, and is biased towards the roller element.

Abstract: A volumetric metering system for metering a product in an agricultural machine is presented. In one example, the volumetric metering system comprises a roller element, a drive mechanism configured to rotationally drive the roller element to convey the product along a conveyance path to a product receiving component, and a guide element disposed on a side of the roller element. The guide element is configured to guide the product along the conveyance path, and is biased towards the roller element.

Abstract: A drive assembly for a combine head includes a hub and a bearing received over a portion of the hub. The bearing defines a rotational axis of the hub. A plane passes radially through the bearing relative to the axis. A sprocket is coupled to the hub and is coaxial with the bearing. The sprocket has a plurality of teeth located around a perimeter of the sprocket, the plurality of teeth being located so that the plane passes radially through the plurality of teeth.

Abstract: The invention comprises a point and cover assembly for a row crop header including a point; a cover coupled to the point with a hinge; a latch fixed to the cover, the latch having a first spring-loaded latch pin for pinning the cover to a first row unit, a second spring loaded latch pin for pinning the cover to a second row unit, and a member coupling the two latch pins together that is operable by one hand to release both latch pins; and a point support fixed to the cover, the point support comprising an elongate member fixed at its rear end to the cover and having an adjustable point rest at its front end for supporting the point at a plurality of different heights.
