A compression roll housing for an agricultural machine, having a side panel provided with at least one elongated aperture for receiving a shaft of a compression roll and allowing movement of the shaft within the aperture. The housing is provided with a cover plate which rotates about an axis parallel to the shaft and is provided with an indentation to partially surround the shaft. Movement of the shaft, such as along a longitudinal axis of the aperture, causes the plate to rotate to provide a cover across the aperture to prevent the escape of any material from the housing.

Subfield moisture model improvement in generating overland flow modeling using shallow water calculations and kinematic wave calculations is disclosed. In an embodiment, a computer-implemented data processing method comprises: receiving precipitation data and infiltration data for an agricultural field; obtaining surface water depth data, surface water velocity data, and surface water discharge data for the same agricultural field; determining subfield geometry data for the agricultural field; executing a plurality of water calculations and wave calculations using the subfield geometry data to generate an overland flow model that includes moisture levels for the agricultural field; based on, at least in part, the overland flow model, generating and causing displaying a visual graphical image of the agricultural field comprising a plurality of color pixels having color values corresponding to the moisture levels determined for the agricultural field. Output of the overland flow model is provided to control computers of seeders, planters, fertilizer spreaders, harvesters, or combines to control seeding, planting, fertilizing or irrigation activities in the field.

A harvester may include a crop path along which crops are moved, a working member to interact with weed seeds moving along the crop path and a controller. The controller is to receive data indicating forthcoming weed seeds and is to output control signals controlling the working member based on the data.

A crop divider assembly for a harvesting header includes a housing defining an interior cavity and including a forwardmost end. A divider rod has a first end and a second end, where the first end is coupled to the forwardmost end of the housing. A light-emitting mechanism is coupled to the second end of the divider rod. The divider rod extends upwardly from the forwardmost end, and the light-emitting mechanism is positioned at a location above the forwardmost end of the housing.

An agricultural vehicle including a chassis and a sectional header system carried by the chassis. The sectional header system includes a center section connected to the chassis, at least one additional section, and at least one coupling assembly that removably connects the center section to the at least one additional section. The at least one coupling assembly includes at least one actuator connected to the center section and the at least one additional section. The at least one actuator is located underneath the pivot point. The at least one additional section is configured for being coupled to the center section in harvesting of a crop material and decoupled from the center section and subsequently towable in transportation of the sectional header system.

A transport system for a harvesting header including at least one dolly wheel being laterally shifted towards the main header frame with an acute angle relative to an elongate tongue where the acute angle allows the centerline of the harvesting header to travel essentially colinear with the centerline of the towing vehicle. The transport system may be further provided with gauge wheels being repositionable for use as a trailing wheel assembly and/or the at least one dolly wheel.

A system includes a vehicle system. The vehicle system includes at least one sensor and a mapping server system communicatively coupled to a mapping client system. The mapping server system is configured to receive a signal from the at least one sensor; update a mapping tile disposed in a tile cache to derive an updated mapping tile based on the signal; and visually display the mapping tile to an operator of the vehicle system.
