A work machine is provided with grade control capability using an imaging system, e.g., rather than GPS. The work machine includes at least one work implement for working at least part of a terrain, and first sensors (e.g., cylinder sensors) generate signals corresponding to positions of the work implement. Second sensors (e.g., stereo cameras) generate signals corresponding to positions of representative features of the terrain (e.g., curbs) in a field of view. A controller receives the signals and determines in a local reference system independent of a global reference system: first position information corresponding to the work implement; and second position information corresponding to the representative features. According to a selected control mode, target parameters for the work implement are determined based on the second position information corresponding to the representative features, and output signals are generated corresponding to a difference between the first position information and the target parameters.

A retention assembly, to slidably retain a blade to a support bracket of a grader machine, includes a yoke, a bearing arrangement, and one or more pins. The yoke is adapted to be coupled to the support bracket, and includes a first sidewall, a second sidewall, and a cavity defined therebetween. The first sidewall defines a first thickness and one or more first bores. The second sidewall defines a second thickness and one or more second bores. The second bores are correspondingly co-axial to the first bores. The bearing arrangement is received within the cavity and is adapted to support the blade for a sliding movement of the blade relative to the bearing arrangement. Further, the pins extend correspondingly through at least one of the first bores or the second bores, and into the cavity to engage and retain the bearing arrangement within the cavity.

A control system is disclosed for use with a machine. The control system may have a first blade mountable to the machine and configured to engage a ground surface below the machine, and at least a first actuator configured to move the first blade. The control system may also have a second blade mountable to the machine and configured to engage the ground surface below the machine, and at least a second actuator configured to move the second blade. The control system may additionally have a controller in communication with the at least a second actuator. The controller may be configured to determine a first position of the first blade, and to automatically cause the at least a second actuator to move the second blade to a second position based on the first position of the first blade.

A construction machine comprising a chassis, a steering, and a powertrain for driving the construction machine by the chassis, an earth-moving tool for working a terrain, and a measuring system having a first measuring unit configured for generating first measuring data in a first detection range and comprising at least a first camera and a first LiDAR scanner configured for rotating a first measuring beam around a first axis and around a second axis non-parallel to the first axis with a rotating speed of at least 0.5 Hz with respect to each axis, an interface connecting the first measuring unit to a computer configured for, based on the first measuring data, at least one of generating a three-dimensional model of the terrain within the first detection range, identifying an obstacle or a person within the first detection range, and controlling the steering, the powertrain, and/or the earth-moving tool.

A retention assembly to slidably retain a blade to a support bracket of a grader machine. The retention assembly includes a yoke adapted to be coupled to the support bracket, and the yoke includes a base wall, a first sidewall extending directly from the base wall, the first sidewall being configured to face the blade, and a second sidewall extending directly from the base wall, the second sidewall configured to face away from the blade and spaced apart from the first sidewall to define a cavity therebetween, along with the base wall. A retainer extends from at least one of the first sidewall, the second sidewall, and the base, and a bearing arrangement is received within the cavity and adapted to support the blade for sliding movement of the blade relative to the bearing arrangement. The retainer engages the bearing arrangement and retains the bearing arrangement within the cavity.

One embodiment is a work machine including an actuator coupled with a chassis, a suspension coupled with the actuator, and a tool mount coupled with the suspension. A grading tool assembly is coupled with the tool mount. A wireless receiver is coupled with the suspension. An electronic controller in operative communication with the receiver and the actuator is structured to adjust the actuator in response to a signal received by the receiver effective to simultaneously adjust the position of the receiver and the force applied to the suspension. A grading indicator is coupled with the suspension and provides a visually perceptible indication of a current state of grading relative to a desired state of grading.

A debris blower system for clearing debris from the path of a road grader. The debris blower system generally includes a mounting platform configured to mount to a road grader, a blower unit attached to the mounting platform, an exhaust tube attached to the blower unit, and a motor attached to the mounting platform. The exhaust tube may be configured to rotate relative to the blower unit to alter the flow of air from the blower unit. The motor is configured to rotate the exhaust tube and alter the direction of air from the blower, which is generally to a road surface in front of a road grader. The debris blower system may also be attached to a lifter, which permits the mounting platform to be raised and lowered to further control the outflow of air from the blower unit.

A control method is performed in a motor grader, the motor grader including a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. The control method includes detecting a load applied to the blade and revolving, when the detected load is larger in value than a predetermined reference value, the swing circle in such a direction that the blade angle is smaller than the blade angle at the time of detection of that value.

A work vehicle capable of accurately obtaining current topography to be worked is provided. A motor grader includes a vehicular body frame, a blade, and a camera. The blade is arranged between a front end of the vehicular body frame and a rear end of the vehicular body frame. The camera is configured to obtain current topography in front of the vehicular body frame. The camera is attached to the vehicular body frame. The camera is arranged in front of the blade.

A control method in a motor grader including a running wheel, an inclination mechanism which inclines the running wheel, an operation portion, and a sensor capable of detecting whether or not the running wheel is at an erect position includes outputting from a controller, a control signal for driving the inclination mechanism in response to an operation command in accordance with a state of operation onto the operation portion and stopping output of the control signal in response to the operation command when the sensor detects the erect position.
