A control system for a work vehicle includes an acceleration detection device and a controller. The acceleration detection device detects an acceleration of the work vehicle. The controller determines whether the acceleration is greater than a first threshold and reduces the a vehicle speed when the acceleration continues to be equal to or greater than the first threshold over a predetermined first determination time period.

A work vehicle includes a rotary member, a support member, a sealing ring, a pressure controller, and a vehicle speed determination component. The rotary member has a first hydraulic fluid supply channel to supply the hydraulic fluid to the steering clutch, and is rotated by power from the transmission when the steering clutch is engaged. The sealing ring is disposed between the rotary member and the support member and is mounted adjacent to the connected part between the first hydraulic fluid supply channel and the second hydraulic fluid supply channel. The pressure controller controls the engagement pressure to be a specific first pressure when the vehicle speed is determined not to be equal to or greater than a specific speed, and controls the engagement pressure to decrease from the first pressure when the vehicle speed is determined to be equal to or greater than a specific speed.

A device may receive machine data indicating a pose of one or more components of a machine. The machine data may be generated based on first data from one or more first sensor devices associated with the machine. The device may generate validation data to validate the machine data. The validation data may be generated based on second data from a second set of sensor devices. The device may perform a comparison of the machine data and the validation data and determine, based the comparison, whether the machine data is validated or not validated. The device may selectively control an operation of the machine based on the machine data. Based on determining that the machine data is validated, the operation may be controlled based on the machine data. The operation may be controlled without the machine data based on determining that the machine data is not validated.

The present disclosure is directed to systems and methods for operating a grading machine. The method includes (i) receiving information indicating a current position of a moldboard of the grading machine; (ii) determining if the moldboard is moving toward an avoidance zone, and the avoidance zone is defined by a distance from a scarifier of the grading machine; and (iii) in response to a determination that the moldboard is moving toward the avoidance zone, adjusting at least one operating parameter of the moldboard or the scarifier of the grading machine.

A system includes a processor and a display. The processor acquires shape data indicative of a shape of the surroundings in a traveling direction of a work machine. The processor generates a guide line. The guide line is disposed spaced from the work machine. The guide line indicates the shape of the surroundings in the traveling direction of the work machine. The processor synthesizes a surrounding image and the guide line and generates an image including the surroundings image and the guide line. The display displays the image including the surroundings image and the guide line based on a signal from the processor. The system may further include the work machine, a camera that captures the surrounding image, and a sensor that measures the shape of surroundings.

An example bushing of a hydraulic hammer tool includes a bulk region and an inner region. The inner region has a relatively greater hardness than the bulk region. The inner region may also be compressively stressed, while the bulk region may have tensile stress. The stress and/or hardness profile of the bushing may enhance its resistance to wear and galling defects when a hammer of the hydraulic hammer tool is held in alignment by the bushing. The bulk region of the bushing may be relatively soft, resulting in the bushing having a relatively high level of toughness. The bushing may be formed using medium to high carbon steel by rough forming the bushing, hardening the bushing, tempering the bushing, induction hardening the inner region of the bushing, and then quenching the inner region.

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 system and method for steering a machine. The system may comprise a controller configured to receive a steering command and determine a target angular turn rate for the body and a target turn direction for the body. The controller may be further configured to determine a steering mode based on a transmission output torque, the steering mode including Traction-steering, Assisted-steering or Implement-steering. When the steering mode is Assisted-steering, the controller is configured to steer the machine in the target turn direction and at the target angular turn rate by (a) moving an implement from a first position to a second position and (b) diverting or removing power from a first ground engaging traction member. When the steering mode is Implement-steering, the controller is configured to move the implement from a first position to a second position to steer the machine in the target turn direction and at the target angular turn rate without diverting or removing power from the first ground engaging traction member.

Provided is a construction machine equipped with a dozer and capable of holding the dozer in an upper position. The construction machine includes a dozer cylinder that brings the dozer into rotational movement, a first cylinder pin, a first connection member joined with an end of the first cylinder pin and defining a first through-hole, a second cylinder pin, a second connection member joined with an end of the second cylinder pin and defining a second through-hole, and a fixing member to be detachably connected to the first and second connection members to interconnect them and thereby fix the dozer in the upper position.
