  • Publication number: 20230240179
    Abstract: Apparatuses and agricultural implements are directed to maintaining engagement of float arms of an agricultural implement with a ground surface, maintaining a consistent load distribution to the ground, and maintaining a height of a cutterbar of the agricultural implement at a selected distance of the ground. An agricultural implement may include a frame configured to couple to an agricultural vehicle, a float arm pivotably coupled to the frame, a cutterbar coupled to float arm, and a biasing component disposed between the float arm and the frame that biases the float arm away from the frame.

  • Publication number: 20230070185
    Abstract: A harvesting machine includes a cutter head having a cutter bar for cutting crop from a ground surface and a rotatable reel located above the cutter bar. Reel arms of the reel each include a plurality of fingers thereon to engage the crop. The cutter head also has an actuator configured to adjust a pitch of the fingers with respect to the reel arms. A controller is operably connected with the cutter head and is configured to receive an input on a cutter head posture relative to the ground surface, with the input on the posture of the cutter head including one or more of a height of the cutter head or an angle of the cutter head relative to the ground surface. The controller operates the actuator to automatically control the pitch of the plurality of fingers based on the received input on the posture of the cutter head.

  • Patent number: 11483977
    Abstract: A harvesting head for a collection machine that harvests material. The head includes conveyor belts to transport material towards the collection machine, and blower heads to help prevent material from falling off the conveyor belts. The conveyor belts can include a feed belt that feeds material towards the collection machine, and a side belt that carries material towards the feed belt. Blower heads can blow across the side belt and towards the center of the feed belt. Blower heads can be located below the side belt. Blower heads can be located near the front of the feed belt and blow towards the collection machine. A feed drum can move material towards the collection machine, and blower heads can blow across the feed drum and towards the feed belt or collection machine. Blower heads can be movable, or have adjustable flow rate, velocity, direction or spread.

  • Patent number: 10617060
    Abstract: An agricultural harvesting head comprises a frame that supports a cutter configured to cut an agricultural product. The agricultural harvesting head also comprises a set of laterally extending and forward tilted feeding tracks that guide the cut agricultural product to a center of the agricultural harvesting head. The set of feeding tracks comprise a base web of elastomer-impregnated fabric, elongated cleats that extend upward from the base web and extend across substantially the entire width of the base web and a plurality of textured protrusions that extend upward from the web between adjacent elongate cleats. The textured protrusions protrude upward from the base web a distance sufficient to catch and hold grain rolling downhill in a direction perpendicular to the direction of travel of the feeding track and extend over substantially the entire width of the base web.
