The present invention provides an autonomous traveling work machine that can accurately receive positioning signals from navigation satellites and autonomously travel without deviating from a traveling path, even in the case of an inclined slope. The autonomous traveling work machine includes a traveling machine body, a positioning receiver that receives positioning signals from navigation satellites, an autonomous traveling control device that performs control for autonomous traveling along traveling paths based on the positioning signals, an inclination detection unit that detects the inclination of the traveling machine body and outputs inclination angle information, an inclination angle determination unit that determines an inclination angle based on the inclination angle information, and a rotation control mechanism that rotates the positioning receiver with one or more degrees of freedom. The rotation control mechanism keeps the positioning receiver horizontal based on the inclination angle.

A grounds maintenance vehicle having a vehicle frame is disclosed. An implement is coupled to the vehicle frame and has a first implement end and a second implement end. A height selection tool is configured to select one vertical position of a plurality of selectable vertical positions, where each vertical position limits a distance between the implement and the vehicle frame. An implement angle selection tool is configured to change the elevation of the first implement end relative to the second implement end and fix the elevation of the first implement end relative the second implement end. The implement angle selection tool has a manually engageable mechanism configured to change the elevation of the first implement end relative to the second implement end when the implement angle selection tool is disengaged.

Systems and methods for automated lockout systems for moving a cutterbar between a rigid configuration and a flexible configuration in response to actuation of one or more gauge wheels. In some implementations, a cutterbar is movable into a rigid configuration in response to extension of a gauge wheel. In some implementations, the cutterbar is movable into a flexible configuration in response to retraction of a gauge wheel. In some implementations, movement of a cutterbar into a rigid configuration occurs simultaneously with extension of a gauge wheel. In some implementations, movement of the cutterbar into a flexible configuration occurs simultaneously with retraction of a gauge wheel. In some implementations, movement of a gauge wheel and a cutter bar is performed in response to fluidic pressure.

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

A boom mower having a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. There is a break-away mechanism that enables the cutting mechanism to pivot relative to the at least one translation assembly.

In one aspect, a system for determining soil clod size distribution as an agricultural implement is being towed across a field by a work vehicle may include a vision-based sensor provided in operative association with one of the work vehicle or the agricultural implement. As such, the vision-based sensor may be configured to capture vision data associated with a portion of the field present within a field of view of the vision-based sensor. Furthermore, the system may include a controller configured to receive vision data from the vision-based sensor. Moreover, the controller may be further configured to analyze the received vision data using a spectral analysis technique to determine a size distribution of soil clods present within the field of view of the vision-based sensor.

A harvesting head for an agricultural combine includes a frame and a support arm coupled to the frame. The support arm is configured to move between an unlocked state in which the support arm is moveable relative to the frame and a locked state in which the support arm is fixed relative to the frame. The harvesting head includes cutting teeth supported by the support arm relative to the frame. The cutting teeth are configured to move relative to the support arm in a reciprocating motion along a longitudinal axis of the frame. The harvesting head includes a gauge member coupled to the frame. The gauge member is configured to sense a height of the frame relative to a surface. The harvesting head includes a control assembly configured to move the support arm into the locked state based on the height of the frame relative to the surface.

A draper header includes a draper frame and a reel arm. The reel arm is coupled to a reel and pivotally coupled to the draper frame. The draper header further includes a cutterbar pivotally coupled to the draper frame. The reel arm and the cutterbar are configured to pivot about the draper frame to adjust a side profile aspect ratio of the draper header from a first aspect ratio to a second aspect ratio. A height of the first aspect ratio is less than a height of the second aspect ratio, and a width of the first aspect ratio is greater than a width of the second aspect ratio.

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.
