A work machine including a frame, a ground-engaging element movably coupled to the frame, a movable grading element, an actuator coupled to the movable grading element to controllably drive movement of the movable grading element engaging material to be graded, a sensor, and a controller. The controller comprises a memory that stores computer-executable instruction and a processor that executes the instructions. The instructions include labelling each of at least a plurality of pixels in a first image as a visual marker; selecting the first image as a reference keyframe; tracking at least one region of a subsequent image including the visual marker relative to the reference keyframe to determine an estimate of the current pose as the work machine moves; and adjusting a position of the movable grading element.

A method for control of a compacting machine including a ground-engaging implement and a compacting drum includes receiving a request to activate the compacting machine, receiving a command to propel the compacting machine, and automatically generating a command to move the implement to a raised position in which the implement does not engage the ground based on: the request to activate the compacting machine, the command to propel the compacting machine, or a determination that the implement is below a threshold height. The method also includes, once the implement is in the raised position, propelling the compacting machine.

A gravel recapturing and sifting apparatus for attachment to a vehicle on a roadway includes a framework that includes a mounting portion selectively coupled to a front of the vehicle and a mounting boom having a proximal end attached to the mounting portion and which extends rearwardly alongside the vehicle. The apparatus includes at least one wheel assembly coupled to an outer face of the mounting boom and being outwardly offset relative to the outer face, the at least one-wheel assembly including a wheel having a plurality of tines and that is rotatable when actuated. The tines are spaced apart and radially arranged so as to kick up and urge gravel in a direction toward the mounting boom while allowing grass and weeds to pass through in an opposite direction.

A rotary frame includes a first connecting member of the rotary frame has an arc-shaped concave part. Each second connecting member is non-coplanar with the first connecting member and has a mounting hole. A first reinforcing member is connected between a first end of the first connecting member and one of the second connecting members; and another first reinforcing member is connected between a second end of the first connecting member and the other second connecting member. A second reinforcing member is connected between a middle part of a circumferential edge of the first connecting member and one of the second connecting members; and another second reinforcing member is connected between the middle part of the circumferential edge of the first connecting member and the other second connecting member. Middle regions of the first and second reinforcing members joined to the same second connecting member are separate from each other.

A crawler dozer includes a main frame having a longitudinal central axis. A push frame includes left and right push beams. A dozer blade is pivotally connected to the left and right push beams. At least one tilt cylinder is connected between the dozer blade and at least one of the left and right push beams. The tilt cylinder includes a larger cylinder portion pivotally connected to the dozer blade and a smaller piston portion pivotally connected to the at least one of the left and right push beams. The tilt cylinder includes a cylinder axis diverging laterally outward relative to the longitudinal central axis of the main frame in a forward direction by a splay angle of at least 2 degrees.

A tool bit includes a threaded portion, a shank, a shoulder, an anti-rotation segment and a working portion. The threaded portion may be centered about and extend longitudinally along a first axis. The shank may be centered about the first axis and extend longitudinally along the first axis. The shank may be disposed between the threaded portion and the shoulder. The anti-rotation segment may be disposed between the shoulder and the working portion of the tool bit. The working portion may be oriented to extend lengthwise away from the first axis and to extend lengthwise along another axis that is transverse to the first axis. The working portion may include a planar cutting surface that includes a working edge. The planar cutting surface may be oriented transverse to the first axis.

A work vehicle includes a work implement. A control system for the work vehicle includes an operating device and a controller. The operating device outputs an operation signal indicative of an operation by an operator. The controller communicates with the operating device and controls the work implement. The controller determines a first target design topography. The controller generates a command signal to operate a work implement in accordance with the first target design topography. The controller obtains a displacement amount of the work implement with respect to the first target design topography upon receiving the operation signal indicative of the operation of the work implement during work in accordance with the first target design topography. The controller determines a second target design topography based on the displacement amount. The controller generates a command signal to operate the work implement in accordance with the second target design topography.

A motor grader having ride control for dampening machine bounce using a DCM assembly rotatably coupled to and suspended from a frame of the motor grader is disclosed. Each lift cylinder for the DCM may have an associated ride control circuit with an accumulator, a ride control conduit fluidly connected to a carry end of the lift cylinder and having a flow restriction element, and a ride control accumulator valve fluidly connected to the accumulator and the ride control conduit and operable to either block or allow fluid communication between the carry end and the accumulator through the flow restriction element. Each rid control circuit may also include a head end valve fluidly connected to between the head end of the lift cylinder and a low pressure fluid reservoir and operable to block or allow fluid communication between the head end and the low pressure fluid reservoir.

The application relates to a robust self-propelled device, having an oblong shape and a self-supporting housing (1) of the exoskeleton type, having attached a winch (10) and that is supported by a rail track (8), comprising active parts and supporting parts: a levelling blade (2) connected by means of swiveling rods (9) to the housing exoskeleton and in the top part thereof to a laser receiver (6) by a removable graduated rod (5), also in the rear part it is provided with an active device for placing ducts (3).
