A vehicle supported implement for handling separate loads independently, and related methods of use, are presented. The implement is configured to move a load, such as a hay bale, rotating the load radially about an axis, from a first position at a first elevation to a second position at a second elevation. It includes a first frame member and a second frame member pivotally connected to the first frame member at a joint. The axis of rotation intersects the joint normal to the back side of the first frame member and the second frame member rotates radially about the axis of rotation between the first position and the second position. The implement includes an actuator, such as a hydraulic cylinder, connected to the frame members to control the rotation. The implement includes an attachment feature on the back side to secure it to a vehicle.

A control system for a work vehicle includes a controller. The controller receives actual topography information of a work target. The controller determines a design surface that is positioned below the actual topography. The controller generates a command signal to move the work implement along the design surface. The controller determines if slip of the work vehicle has occurred. The controller raises the design surface when the blade tip of the work implement is positioned below an initial target surface when the slip occurs. The initial target surface is the design surface before the occurrence of the slip.

A work vehicle includes a work implement. A control system for the work vehicle includes an input device and a controller. The controller is configured to communicate with the input device, receive an input signal indicating an input operation by an operator from the input device, acquire vehicle information including a position of the work vehicle when the input signal is received, and orientation information of the work vehicle when the input signal is received, and determine a target design surface indicating a target trajectory of the work implement based on the vehicle information and the orientation information when the input signal is received.

A construction vehicle includes a frame and a linkage assembly. The linkage assembly includes a linkage member and a work implement. The work implement includes a wall structure defining a first edge, a second edge, and a material engaging portion. The work implement also includes a first support plate disposed proximate to the first edge. The first support plate defines a first opening proximate to the material engaging portion. The work implement further includes a second support plate disposed. The second support plate defines a second opening proximate to the material engaging portion. The work implement includes a conduit coupled to the first support plate and the second support plate and defining a cavity. Each of the first and second openings are aligned with the cavity. Further, the work implement also includes a weight member removably received within the cavity defined by the conduit.

The controller is further configured to generate jobsite density information based on the tool engagement and the indication of force exerted on the earth moving tool, the controller being further configured to cause a wireless communication module to provide an indication of the jobsite density for the position indicated by the position detection system to at least one remote device.

A work machine includes a machine frame and a cab supported from the machine frame. At least one pivotal connection between the cab and the machine frame allows the cab to be tilted relative to the machine frame. The pivotal connection includes first and second devises fixed to the machine frame, the first and second devises including first and second aligned pin openings, respectively. A pivot pin is received through the pin openings so that the pivot pin is pivotable relative to the machine frame. A viscous mount includes a housing portion, a plunger portion, and a flexible element connecting the plunger portion to the housing portion. The housing portion is attached to the cab, and the plunger portion is attached to the pivot pin between the first and second devises such that the cab and the viscous mount are pivotable with the pivot pin relative to the machine frame.

A blade operation control part of a blade control device controls operation of a blade such that when a blade load is equal to or less than a first load threshold value and a position deviation is equal to or greater than a position threshold value, the blade is lowered to make the position deviation approach zero. The blade operation control part controls operation of the blade such that the blade is raised regardless of the position deviation when the blade load is equal to or greater than a second load threshold value.
