A controller controls a first drive source and a second drive source based on a rotation speed of a right rear wheel measured by a rotation speed sensor and a rotation speed of a left rear wheel measured by a rotation speed sensor, to thereby independently control a rotation speed of each of a right front wheel and a left front wheel.

A hydraulic circuit for a pair of cylinders of an articulation system includes a pump, a reservoir, a directional control valve (DCV), a pair of actuator valves (AVs) and an articulation charge circuit (ACC). The DCV is fluidly coupled to the pump, the reservoir and the pair of cylinders via a supply line, a fluid return line and a pair of cylinder supply lines (CSLs) respectively. Each CSL has a load check valve (LCV) therein. The AVs are fluidly coupled with the DCV and the pump via a pilot supply line (PSL) for actuating movement of the DCV. The ACC, associated with the PSL and each cylinder supply line downstream of the associated LCV, charges a corresponding CSL with fluid from the PSL for increasing a pressure in the corresponding CSL when the pressure in the corresponding CSL falls below the pressure of fluid associated with the PSL.

A cabin for a machine is disclosed. The cabin may include a floor, a roof, at least one A-post located at a leading end relative to a forward travel direction of the machine, and a C-post located at a trailing end opposite the at least one A-post. The C-post may have first terminal ends located at the floor and second terminal ends located at the roof. The C-post may include a C-shaped beam having the first terminal ends, and a Y-shaped beam structure having the second terminal ends. The Y-shaped beam structure may extend from the C-shaped beam to the roof. The Y-shaped beam structure may include two spaced beams.

A work vehicle includes a cab, a driver's seat disposed inside the cab, a first steering device, a second steering device, a seating sensor, and a control unit. The first steering device is disposed in front of the driver's seat. The first steering device is configured to perform a steering operation of the vehicle. The second steering device is disposed to a side of the driver's seat. The second steering device is configured to perform a steering operation of the vehicle. The seating sensor detects whether or not an operator is sitting in the driver's seat. The control unit disables the steering operation with the second steering device when the seating sensor detects that the operator is not sitting in the driver's seat.

A warning zone system and method is disclosed. The warning zone system can comprise an object detection system, a zone configuration system, and an electronic data processor. The object detection system is arranged on a work vehicle and is configured to detect and classify one or more object obstructions located at a worksite. The zone configuration system is configured to associate position data with the one or more object obstructions and generate object models of the object obstructions based on the associated position data. The electronic data processor is communicatively coupled to each of the object detection system and the zone configuration system and is configured to generate and associate warning zones with each of the object models for display on a user display in near real-time.

A mounting assembly for a blade of a motor grader includes a mounting bracket having a groove, at least one first bore, and a second bore. The mounting assembly includes a wear element disposed in the groove. The wear element includes at least one recess. The wear element is adapted to slidably receive a portion of the blade thereon. The mounting assembly also includes a retention pin disposed in the at least one first bore. The retention pin includes an aperture provided therein. The retention pin is adapted to engage the at least one recess provided on the wear element to limit longitudinal movement of the wear element within the groove. The mounting assembly further includes a lynch pin disposed in each of the second bore and the aperture to limit axial movement of the retention pin within the at least one first bore.

A blade assembly is disclosed. The blade assembly may include a blade having a surface defined between an upper edge and a lower edge of the blade, the lower edge being associated with a cutting edge, and a wear plate attached to the blade. The wear plate may extend along the surface and terminate short of the lower edge. The wear plate may have a plurality of accumulation members.

A motor grader includes a vehicular body, a blade, a front wheel located in front of the blade, two rear wheels located in the rear of the blade, a first sensor which detects a position of the vehicular body as first sensor information, a second sensor which detects an inclination of the vehicular body as second sensor information, a first swing member which rotatably supports both of the two rear wheels arranged in the front and rear relation and is swingably supported by the vehicular body, and a third sensor which detects an angle of swing of the first swing member with respect to the vehicular body as third sensor information. A method of controlling a motor grader includes obtaining the first to third sensor information and calculating positions of the rear wheels based on the obtained first to third sensor information.

A control system is provided for a work vehicle having one or more actuation devices. The control system includes an operator input device configured to receive operator input from an operator of the work vehicle and a controller operatively connected to the operator input device and to the one or more actuation devices. The controller is configured to: receive a control mode selection input including a position control mode selection input or a velocity control mode selection input; receive an actuation request input from the operator input device; determine an operating command corresponding to the actuation request input from the operator input device according to the control mode selection input; and issue the operating command to the one or more actuation devices based on the position or velocity control mode.

A control system is disclosed. The control system may include a first input component to control a lean angle of at least one set of wheels of a machine and to provide a visual and/or tactile indication of the lean angle. The control system may include a second input component to control an articulation angle of an articulated joint of the machine and to provide a visual and/or tactile indication of the articulation angle. The control system may include a third input component to control a rotation angle of an implement of the machine and to provide a visual and/or tactile indication of the rotation angle.
