A work vehicle comprising a frame supported by a ground engaging device. A boom assembly is coupled to the frame. A boom cylinder is coupled to the frame and the boom assembly. An attachment coupler is coupled to a distal portion of the boom assembly. At least one tilt cylinder is coupled to the boom assembly and the attachment coupler. A primary attachment is coupled to the attachment coupler. A secondary attachment is coupled to the primary attachment. The secondary attachment comprises a stand configured to move between a standing mode and a stored mode, wherein the stand automatically moves to the standing mode when it is decoupled from the primary attachment.

A convertible box blade scraper apparatus includes a frame assembly including a first sidewall, a second sidewall, one or more shank support cross-members, a first blade support cross-member having a first scraper blade secured thereto, a second blade support cross-member extending between and secured to the first sidewall and the second sidewall, and having a second scraper blade and a leveling blade secured thereto, and a moldboard support cross-member, the moldboard support cross-member having a moldboard support longitudinal center axis. 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 grading machine includes a machine body, a grading blade, and at least one grading blade sensor configured to sense a position and orientation of the grading blade. The grading machine also includes a drawbar connecting the grading blade to the machine body, at least one drawbar sensor configured to sense a position and orientation of the drawbar, a user interface, and a control system. The control system may be configured to receive an input from the user interface and perform an automatic turnaround operation.

A joint orientation system is provided for a work vehicle having a chassis and an implement coupled to the chassis at a joint. The joint orientation system includes a first IMU positioned on a first side of the work vehicle relative to the joint and configured to collect a first IMU acceleration and a first IMU angular velocity and a second IMU positioned on a second side relative to the joint and configured to collect a second acceleration and a second angular velocity of the implement. A controller is configured to receive the first and second IMU accelerations and the first and second IMU angular velocities; determine a joint orientation correction based on IMU accelerations and IMU angular velocities; modify an estimate of joint orientation with the joint orientation correction to generate a current joint orientation; and output the current joint orientation for actuation of the implement.

Disclosed is a ground modifying apparatus of a type sometimes known as levellers, typically as used on tractors and skid-steer vehicles. In current practice these are used for preparing, levelling, and contouring the ground. Such device includes at least an accessory body portion supporting a ground modifying accessory or includes a way to attach the same. The apparatus includes a travelling carriage assembly pivotably attached by a carriage pivot, about a rotational axis substantially parallel to a longitudinal axis of the apparatus. The carriage pivot is positioned lower than the center of gravity of the travelling carriage assembly.

A control device receives, from an engine load sensor device, a value of an engine load of an engine of an equipment operating in an operating environment. The control device compares the value of the engine load to a target engine load range defined by a minimum target engine load value and a maximum target engine load value. Responsive to determining that the value of the engine load is less than the minimum target engine load value, the control device lowers a cutting blade of the equipment to increase an engagement of the cutting blade with a surface or subsurface. Responsive to determining that the engine load is greater than the maximum target engine load value, the control device raises the cutting blade of the equipment to decrease the engagement of the cutting blade with the surface or subsurface.

A system associated with an implement of a machine is provided. The system includes a plane determination module configured to determine a track plane based on a relationship between at least two tracks of the machine. The system also includes an implement control module. The implement control module is configured to compute a location of two or more blade tip points of the implement of the machine in three dimensional space based on at least one constraint of a geometry of the implement. The implement control module is also configured to determine a blade tip point plane based on a relationship between at least two blade tip points of the implement. The implement control module is further configured to compare the blade tip point plane with the track plane and determine if the blade tip point plane is parallel to the track plane based on the comparison.

A levelling apparatus, typically as used on tractors, excavators and skid-steer vehicles includes a blade body portion and body mounting portion connected by an arrangement of fixed and adjustable linkages, preferably hydraulic, to allow movement of the blade body portion (relative to the body mounting portion) in substantially an up and down direction, as well as rotational movement about an axis perpendicular to the general plane of an attached blade.

The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

An embodiment of the present disclosure relates to a blade support frame for a dozer, which supports a blade, the blade support frame including: a ball joint configured to support the blade so that the blade is rotatable; a front plate coupled to the ball joint; an upper plate disposed on an upper portion of the front plate and coupled to the front plate; a lower plate disposed on a lower portion of the front plate and coupled to the front plate; and an inner diaphragm disposed between the upper plate and the lower plate and configured to support a portion between the upper plate and the lower plate.
