A sensor coupler adapted to operatively connect a sensor to a piston-cylinder assembly. The sensor coupler includes a first end member and a second end member. The first end member is disposed on a port of the piston-cylinder assembly, in communication with the sensor, and the second end member is disposed in a cylinder chamber of the piston-cylinder assembly. Further, one or more cables are extending between the first end member and the second end member. The one or more cables are configured to transmit signals indicative of a position of a piston in the piston-cylinder assembly to the sensor. The sensor coupler further includes a biasing member to connect the first end member and the second end member.

A system for automated control of a motor grader includes a first sensor to indicate bounce of the motor grader and a speed sensor to indicate the ground speed. A controller determines a maximum amplitude of the bounce of the motor grader and controls the ground speed of the motor grader at least in part based upon the maximum amplitude of the bounce. A method is also provided.

An articulation control system is disclosed for use with a mobile machine having a traction device. The articulation control system may have a speed sensor configured to generate a first signal indicative of a travel speed of the mobile machine, a steering angle sensor configured to generate a second signal indicative of a steering angle of the traction device, and an articulation actuator configured to articulate a front frame of the mobile machine relative to a rear frame of the mobile machine. The articulation control system may also have a controller in communication with the speed sensor, the steering angle sensor, and the articulation actuator. The controller may be configured to track a travel path of the front frame based on the first and second signals, and to regulate operation of the articulation actuator to cause the rear frame to follow the travel path of the front frame.

An implement mounting arrangement for a work machine providing simplified, independent lift-roll and pitch-yaw operability. The present arrangement includes at least one push arm connected to the work machine for rotation about a horizontal lift axis; an implement support frame mounted to the at least one push arm for rotation about a roll axis and including a lift arm extending cross-wise to the roll axis, the lift arm including a first terminal end and an opposite second terminal end located respectively on opposite sides of the roll axis in spaced relation thereto; an implement mounted to the implement support frame for rotation about a pitch axis and about a yaw axis; a pair of lift-roll cylinders operably connected between the work machine and the respective terminal ends of the lift arm; and a pair of pitch-yaw cylinders operably connected between the implement and the respective terminal ends of the lift arm; wherein the lift-roll cylinders are operable to rotate the support frame and the implement about the lift axis and about the roll axis relative to the work machine independently of the pitch-yaw cylinders, and the pitch-yaw cylinders are operable to rotate the implement about the pitch axis and about the yaw axis relative to the implement support frame independently of the lift-roll cylinders.
