A work machine includes a vehicle body, and a plurality of radar devices. The vehicle body includes a front frame and a rear frame, traveling wheels disposed on the front frame, and traveling wheels disposed the rear frame. The rear frame is relatively operably connected to the front frame by an articulated mechanism. The plurality of radar devices are positioned on right and left sides of a central axis that extends along a front-rear direction of the rear frame. The plurality of radar devices are installed at a rear part of the vehicle body. Each radar device of the plurality of radar devices includes a detector configured to detect an object, and the detector is installed facing outward from a direction parallel to the central axis.

An operator seat is arranged in a cab. An air-conditioning unit is arranged in front of the operator seat. A lower window through which the outside can be seen from the inside of the cab is arranged in front of the operator seat and laterally to the air-conditioning unit.

A payload detection system for automated payload tip-off of a loading operation includes a tip-off controller. The tip-off controller is configured to receive a signal of a remaining payload target; receive a signal of a material weight within an implement and a signal of an angle of the implement; and determine a tip-off threshold based on the material weight and the remaining payload target. The tipoff controller initiates a bulk dump sequence if a difference between the material weight and the remaining payload target is greater than the tip-off threshold and initiates a slow dump sequence if the difference is below the tip-off threshold. The bulk dump sequence includes a single implement actuation to induce material spill until the tip-off threshold is met and the material is staged. The slow dump sequence includes a plurality of dump then rack actuations to induce and then prevent material spill until the remaining payload target is met, each dump actuation having an associated dump angle and each successive dump angle is progressively smaller.

A mobile work machine includes an operator compartment having an operator interface mechanism configured to receive operator input, a control system configured to generate a control signal to control the mobile work machine in an unmanned operation mode, a machine state detection system configured to detect a machine state of the mobile work machine in the unmanned operation mode, and a visualization system configured to control a visual indicator mechanism in the operator compartment to generate a visual indication of the detected machine state.

A work vehicle includes a work implement and a controller. The work implement includes a vehicular body that travels in excavation, a boom pivotable with respect to the vehicular body, and a bucket pivotable with respect to the boom. The controller calculates a direction of a cutting edge of the bucket, determines a direction of movement of the cutting edge by an excavation operation such that an excavation angle between the calculated direction of the cutting edge of the bucket and the direction of movement of the cutting edge by the excavation operation keeps a predetermined angle, and causes the work vehicle to perform the excavation operation in the direction of movement.

Provided are a cab for a work machine and a work machine capable of preventing a door from opening against an operator's intention. The cab includes a cab body, a door, and a gas spring. The cab body is formed with a doorway. The door is rotatably supported on the cab body. The door opens and closes the doorway. The gas spring biases the door in the closing direction.

A work machine includes a vehicle body, a rearward detecting section, and a control section. The vehicle body includes a traveling unit and a work implement disposed in front of the traveling unit. The rearward detecting section is configured to detect an object when traveling in reverse due to driving of the traveling unit. The control section is configured to decide to validate or invalidate a first control according to a detection of the object, a state of traveling in reverse, and a scooping work state by the work implement. The control section is configured to decide to validate the first control based on the scooping work state when the first control is invalidated.

Provided is a work vehicle which can prevent an engine from stalling regardless of type of a system mounted on a vehicle body. In a wheel loader 1 equipped with a loading work device 11 operated by an electric operation lever 19, first and second directional control valves 5, 6 include neutral positions 5N, 6N for causing hydraulic oil discharged from a hydraulic pump 12 to return to a hydraulic oil tank 10, respectively, and in the case where a discharge pressure P of the hydraulic pump 12 is a main relief pressure Pr or more and an engine rotational speed N is less than a low idle rotational speed NL, a controller 2, 2A restricts the output of control signals to first and second solenoid control valves 3, 4 so as to cause the first and second directional control valves 5, 6 to be switched to the neutral positions 5N, 6N, respectively.

A work vehicle includes a vehicle body, a work implement including an attachment, an operating device and a controller. The operating device can be operated to a dump side and a tilt side to cause the attachment to dump and tilt. The controller executes an automatic drive control in which the attachment is caused to dump as far as a predetermined dumping position when the operating device is operated by a first dump operation amount or greater to the dump side, or to tilt as far as a predetermined tilt position when the operating device is operated by a first tilt operation amount or greater to the tilt side. The controller disables the automatic drive control when a switching time period required for the operating device to be switched between the tilt and dump sides is at least a predetermined disabling time period.

A work machine having a cab coupled to a frame, a steering system coupled to the frame, a controller configured to selectively articulate the steering system, a joystick assembly positioned in the cab and in communication with the controller, a steering wheel assembly positioned in the cab and configured to selectively articulate the steering system, and a steering wheel sensor coupled to the steering wheel assembly and in communication with the controller to identify movement of the steering wheel assembly. Wherein, the controller does not articulate the steering system responsive to movement of the joystick assembly when the steering wheel sensor identifies movement of the steering wheel.
