An agricultural vehicle including a chassis and a header connected to the chassis. The header includes a frame, at least one crop divider connected to the frame and having a crop divider body with at least one opening therein, and at least one down crop gatherer rotatably mounted to the at least one crop divider and at least partially extending through the at least one opening of the crop divider body. The at least one down crop gatherer has a first rotational direction. The header also includes a drive unit rotatably mounted to the at least one crop divider and contacting the at least one down crop gatherer. The drive unit has a second rotational direction and is configured for contacting the field and driving the at least one down crop gatherer in its first rotational direction.

A row unit for a header of an agricultural harvester is provided. The row unit includes a frame, a first deck plate assembly mounted to the frame, and a second deck plate assembly mounted to the frame. The first and second deck plate assemblies each include a deck plate, a plurality of deck plate segments extending from the deck plate and moveable between a first position and a second position relative to the deck plate, and a plurality of biasing members for biasing each respective deck plate segment. The row unit includes both operator controlled macro adjustment and automatic micro adjustment of a gap between the first deck plate assembly and the second deck plate assembly. The micro adjustment is achieved through biasing members biasing each respective deck plate segment.

A row unit for a header of an agricultural harvester is provided that includes a frame and two spaced apart stripping plates. The row unit further includes a first stalk roll mounted to the frame adjacent the first stripping plate and a second stalk roll mounted to the frame adjacent the second stripping plate. The first stalk roll includes a primary helical flight having a front end that starts at a front edge of the first stalk roll and the second stalk roll includes a secondary helical flight having a front end that starts at a position axially spaced from a front edge of the second stalk roll.

An agricultural harvester has a chassis, a forward frame fixed to the chassis, and a lateral support bar movably coupled to the forward frame, with the lateral support bar being at least partially positioned within the forward frame. The agricultural harvester further includes a base cutter coupled to the lateral support bar, and a finned roller coupled to the lateral support bar such that movement of the lateral support bar moves the base cutter and the finned roller together.

A system for detecting foreign objects within an agricultural harvester may include a feed roller assembly configured to receive and direct the flow of harvested materials along a flow path defined between a plurality of bottom rollers and a plurality of top rollers from a first end of the feed roller assembly to a second end of the feed roller assembly. The system may further include a first movement sensor configured to generate displacement data indicative of displacement of a first roller of the plurality of top rollers, a second movement sensor configured to generate displacement data indicative of displacement of a second roller of the plurality of top rollers, and a controller configured to determine when a foreign object is present within the flow of harvested materials based at least in part on the displacement data received from the first and second movement sensors.

One or more techniques and/or systems are disclosed for automatically adjusting conditioning rollers of a windrower implement, such as those used to condition hay and other windrowed crops. Adjustments can be made on the fly to rollers used to condition the crop based on several factors such as the condition of the crop, the density, speed, header conditions, and more. Sensors can be used to detect the crop's and others' conditions, and automatic adjustments can be made, such as the distance between conditioning rollers, and/or the pressure applied by the rollers, to meet a desired crop condition for the windrows.
