The apparatus further includes an elongated moldboard having an arc-shaped front surface that extends between a moldboard top edge and a moldboard bottom edge, the moldboard including one or more pivot arms rotatably coupled to the moldboard support cross-member to provide the moldboard with a pivot axis, wherein the pivot axis is coincident with the moldboard support longitudinal center axis, and further including a hitch assembly.

A drawbar-circle-moldboard assembly for a work machine includes a drawbar, a circle assembly, and a moldboard. The drawbar is configured to be pivotably connected to a frame of the work machine. The circle assembly is rotatably connected to the drawbar and includes a circle member formed from a hollow box section. The moldboard is connected to the circle assembly.

A bucket claw system and method of use wherein the bucket claw system comprises a bucket, either wedge shaped or flat bottomed, that is attached to a piece of heavy equipment such as a loader or skid-steer, wherein the bucket further comprises a plurality of teeth on the outside of the bucket, on the back portion of the bucket, in the area of the transition from the bottom portion of the bucket and the back portion. The bucket claw system can be used by rotating the front edge of the bucket up, exposing the plurality of teeth to the ground, and then moving the plurality of teeth along the ground in order to clear an area of scrap limbs, brush, vines, grass, roots, and undergrowth.

A lever-operated motor grader can include a front end including a pair of steerable tires connected to the front end; a rear end pivotally connected to the front end at an articulation joint, the rear end including a power source operatively coupled to at least two driven tires; a drawbar-circle-moldboard assembly having a blade, the drawbar-circle-moldboard assembly configured for moving the blade into various orientations, the blade movement controlled by a hydraulic system coupled to one or more operator-controlled levers of the motor grader; a controller; and a pressure sensor coupled to the hydraulic system of the blade to deliver to the controller a signal corresponding to a pressure of the hydraulic system; wherein the controller receives the signal corresponding to the pressure of the hydraulic system, and wherein the controller is configured to determine an application of the motor grader based on the received signal.

A road drag implement includes a frame, a hitch assembly, rear wheels and a two grading blades. The frame is supported by the rear wheels and the hitch assembly. The rear wheels and the hitch assembly have articulating support structures that are able to be controllably positioned between a raised transport positions and lowered working positions. A first blade assembly and a second blade assembly are pivotably mounted to the frame. The first blade assembly is in a forward position on the right side of the frame and the second blade assembly is behind the first blade assembly on the left side of the frame. Actuators connect between the frame and each respective blade assembly which are able rotate the blade assemblies between a first retracted position for transport and a second extended position for road work.

A vehicular accessory system includes a first accessory pivotable in a first direction via pressurized fluid at a first actuator and pivotable in a second direction via pressurized fluid at a second actuator, and a second accessory pivotable in a third direction via pressurized fluid at a third actuator and pivotable in a fourth direction via pressurized fluid at a fourth actuator. A valve assembly is in fluid communication with the first, second, third and fourth actuators. Responsive to pivoting of the first accessory to a first fully pivoted orientation, the valve assembly automatically operates to supply pressurized fluid to the third actuator to pivot the second accessory in the third direction. Responsive to pivoting of the first accessory to a second fully pivoted orientation, the valve assembly automatically operates to supply pressurized fluid to the fourth actuator to pivot the second accessory in the fourth direction.

A grading machine includes a machine body, a grading blade, a drawbar connecting the grading blade to the machine body, a blade sideshift cylinder and a blade sideshift cylinder rod, a user interface, and a control system. The control system may be configured to receive an input from the user interface and extend or retract the blade sideshift cylinder to adjust a sideshift of the grading blade to one of a plurality of predetermined sideshift positions based on the input.

A work vehicle includes a work implement operatively connected to a frame through an actuator having a cylinder and a piston rod. Control circuitry is operatively connected to the actuator and includes a processer and a memory, wherein the memory is configured to store program instructions and the processor is configured to execute the stored program instructions to: identify one of an initial retracted reference position of the piston rod based on an initial minimum retracted distance or an initial extended reference position of the piston rod based on an initial maximum extended distance; identifying an end of stroke position of the piston rod after identifying one of the initial retracted reference position of the piston rod or the initial extended reference position of the piston rod; and moving the work implement with respect to the work vehicle based on a work implement command modified by the identified end of stroke position.

In accordance with one or more aspects, a circle drawbar for a motor grader has a drawbar frame having two elongated members, and a circle frame that has a surface defined by an inner and outer diameter. The circle frame has a circle gear located radially inward of the inner diameter, allowing the circle frame to be rotatable relative to the drawbar frame around an axis of the circle gear. A platform having a top, bottom, and an edge depends from the drawbar frame and covers the circle gear. A debris remover is connected to the platform and removes debris from the surface of the circle frame as the circle frame rotates.
