An agricultural equipment air screen cleaning assembly having a frame having an airflow opening having a non-circular outer perimeter, a screen mounted to the frame within the airflow opening and extending to the non-circular outer perimeter, a motor, and a suction wand operatively connected to the motor and located on an upstream side of the screen. The suction wand is rotatably connected about a rotation axis at a central region of the screen, and includes: at least one distal end that is movable in a radial direction with respect to the rotation axis to follow the non-circular outer perimeter as the suction wand rotates about the rotation axis, one or more inlet openings facing the screen, and an internal suction flow path in fluid connection with the one or more inlet openings, the suction flow path extending from a manifold to the distal end of the suction wand.

An agricultural vehicle header suspension having a frame, a plurality of supports extending forward from the frame, an anchor plate, a frame pivot joining the frame to the anchor plate to be rotatable about a frame pivot axis, a frame actuator connected between the anchor plate and the frame and configured to resiliently hold the frame at a predetermined position relative to the anchor plate, and to allow the frame to move through a range of motion relative to the anchor plate, upon compression and/or extension of the frame actuator. The frame actuator may be, for example, at least one single-acting hydraulic actuator, mechanical spring, or a pneumatic cylinder.

A combine grain cleaning system having front and rear rollers, a conveyor belt having an upper surface extending from the front roller to the rear roller, a motor operatively connected to the conveyor belt and configured to drive the upper surface in a belt travel direction from the front roller to the rear roller, and a baffle located adjacent the rear roller. The baffle has a leading edge, a trailing edge located behind the leading edge with respect to the belt travel direction and below the leading edge with respect to a vertical direction, and a baffle surface extending from the leading edge to the trailing edge. One or more sieves are located below the baffle, and a fan is provided to direct an airflow at least partially upwards in the vertical direction adjacent the rear roller. A method for separating grain is also provided.

An agricultural vehicle header includes a frame supporting components of the agricultural vehicle header. A reel is mounted to the frame such that a weight of the reel produces a bending moment on the frame in a first direction that can cause the header to droop toward a ground surface. A gauge wheel is mounted to the frame such that a normal force, which is produced by the gauge wheel on the ground surface, is transmitted to the frame to cause a bending moment on the frame in a second direction that is opposite to the first direction in order to either limit or prevent drooping of the header toward the ground surface.

A harvesting assembly for harvesting a crop includes a frame, a cutting knife configured cut crop, a feed drum, a draper assembly, a first auger assembly, and a second auger assembly. The draper assembly and the auger assemblies are configured to move the cut crop toward to the feed drum. The auger assemblies each include a first auger, a second auger, and a mounting unit coupled to the frame and coupled between the first auger and the second auger to support the first auger and the second auger during rotation of the augers.
