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 motor grader includes a front frame, a rear frame, an actuator that pivots the front frame with respect to the rear frame, an operator operation apparatus, a display apparatus, and a controller. The controller causes the display apparatus to show any one of an image showing a state of pivot and an image different from the image showing the state of pivot, based on a signal from the operator operation apparatus.

The present invention provides a device that comprises a housing with a protection screen and a chain storage rack secured inside the housing. The present invention further includes an attachment plate positioned on the back side of the housing, a winch assembly attached to the housing, a boxed blade attached to the front side of the housing, a plurality of gripper steel teeth attached to the boxed blade, and a plurality of D-rings attached to the housing.

A grading machine include a machine body, a grading blade, at least one grading blade sensor configured to sense a position and orientation of the grading blade, a drawbar connecting the grading blade to the machine body, a drawbar centershift cylinder, a user interface, and a control system. The control system is configured to receive an input from the user interface and position and orient the grading blade and the drawbar to one of a plurality of predetermined maintenance positions based on the input.

A land plane that may be moved over an agricultural field to smooth any irregularities in the surface of the field is pulled by a tow vehicle and has a blade assembly in a general diamond shape. The general diamond shape may be between 30 and 35 feet wide and 35 and 40 feet long. Thus, the land plane may have a sufficient length for drag and earth moving capability to economically and properly level a field, and a sufficient width to cover a substantially large area in single pass over the field. Further, the land plane may have foldable wing sections that enable the land plane to be transported over a typical state or county road or highway.

A system, method, and apparatus includes measuring wear of a cutting edge of a blade of a work vehicle. Blade position or calibration measurements are made with or without a cutting edge. A wear condition of the cutting edge is acceptable when the blade position measurement less an acceptable wear to the cutting edge amount is less than a blade calibration measurement. A wear condition of the cutting edge is unacceptable when the blade position measurement less an acceptable wear to the cutting edge amount is greater than a blade calibration measurement. Alternatively, a wear condition of the cutting edge is unacceptable when a blade calibration measurement plus a tolerance margin is greater than the blade position measurement. The wear condition of the cutting edge is acceptable when the blade calibration measurement plus a tolerance margin is less than the blade position measurement.
