A surveying system is provided having a work machine with at least one sensor configured to produce a signal indicative of a longitudinal pitch of the work machine and a lateral roll of the work machine. The work machine additionally includes a locating device configured to determine the location of the work machine, a communicating device configured to communicate over a network, and a controller in communication with the at least one sensor and the locating device. The controller is configured to receive the signals from the at least one sensor, create survey data by linking the signals with the location of the work machine, and communicate the survey data using the communicating device over the network to one or more offboard controllers. At least one offboard controller is configured to compare the survey data to one or more threshold values, calculate variances, and generate a map displaying the variances.

A grade control system for a motor grader configured to adjust the speed of the motor grader based on a difference between a desired grade and a current grade. The difference between the desired grade and the current grade provides a current error signal which is compared to a predetermined acceptable error signal or a predetermined range of acceptable error signals. If the current error signal is outside the range of acceptable error signals, the vehicle is automatically slowed down. If the vehicle is within the range of acceptable error signals, the vehicle speed either remains the same or the vehicle speed is increased to improve productivity, while maintaining the current error signal within the range of acceptable error signals. The desired grade is provided to an electronic control unit resident on the grader from either a 2D cross slope machine control system or a 3D machine control system.

In a motor grader, a total drawbar position may be determined based on signals from various sensors on a drawbar-circle-moldboard (DCM) assembly. The sensors can include rotational sensors for one or both lift arm angles, and one or both yoke primary angles in combination with sensors detecting lengths of the lift cylinders. The sensor information may be used to calculate roll, pitch and yaw angles of the drawbar relative to a frame of the motor grader.

A blade for use with a grading machine comprises an attachment portion, a working portion including a plurality of teeth, each tooth defining a bore, and a plurality of wear resistant inserts retained in the bores of the teeth.

An operator cab for a machine such as a motor grader includes an access door coupled to a frame by way of a hinge mechanism. The hinge mechanism has abutting cam and follower surfaces with geometry to control the swinging of the access door such as under the force of gravity. The cam surface has a double-sloped profile of rotation about the pivot axis of the hinge mechanism so that the access door swing is controlled in either of a first or a second swing direction toward a dwell location of the access door.

A power train is provided having a reduced size and weight. A hydraulic motor includes a rotatable output shaft. Wheel bearings rotatably support a rotatable housing relative to a motor housing. A hydraulic clutch mechanism permits or prohibits rotation of a second carrier of a second planetary gear reducer about the center of rotation of the output shaft. The hydraulic clutch mechanism is disposed on the radially inner side relative to the wheel bearings.

A stand is disclosed for supporting a moldboard and a drawbar of a grading machine. The stand may comprise a base frame and a component support unit. The said stand may be configured to support the moldboard, and the component support unit may be configured to support at least a portion of the drawbar. The base frame and the component support unit may be configured to: (a) support a substantial portion of the moldboard above the base frame; and (b) support a substantial portion of the drawbar above the base frame and the moldboard when the moldboard is supported on the stand.

A moldboard assembly is disclosed. The moldboard assembly may include a blade and a wear strip in sliding contact with the blade. The wear strip may include a high visibility material that is transferred onto the blade at a predetermined percentage of a useful life of the wear strip.

A coordinated control method and system for a work vehicle having a primary implement and a secondary implement and one or more controllers. The controller(s) receive a primary implement position input, which is used to generate a primary implement control command to drive one or more primary actuators to position the primary implement. The controller(s) generate a secondary implement control command that is coordinated with the primary implement position input to drive one or more secondary actuators to position the secondary implement in a relative orientation with respect to an orientation of the primary implement resulting from the primary implement control command.
