A grounding rod having an elongated metal rod, an adjustment member, and a bracket. The bracket is attached to a metal portion of a piece of machinery. The adjustment member is mechanical, electric, or hydraulic and raises and lowers the elongated rod from a transport position where the elongated rod does not engage the ground, to a lowered position where the elongated rod is pushed into the ground.

A GNSS antenna and an inertial measurement unit are placed at a longitudinal center of a unit base mountable onto a work vehicle. A wireless communication unit is placed at the longitudinal one end side of the unit base. A wireless communication antenna of the wireless communication unit is placed in a front part of the unit base, which is located on the front side of a vehicle body when the unit base is mounted on the work vehicle. The GNSS antenna is provided above the inertial measurement unit.

A hydraulic fluid pressure amplifier system includes a boost cylinder assembly, an energy storage device in fluid communication with the boost cylinder assembly, and a working cylinder assembly. The boost cylinder assembly is configured to selectively receive a plunger member into a boost cylinder, wherein movement of the plunger member received in the boost cylinder compresses a charge fluid within a blind side volume of the boost cylinder from a first fluid pressure to an amplified fluid pressure greater than the first pressure. The working cylinder assembly is selectively operable responsive to receiving a source hydraulic fluid having a nominal fluid pressure less than the amplified fluid pressure for effecting the movement of the plunger member into the boost cylinder. The energy storage device is operable to selectively receive and store a portion of the charge fluid compressed to the amplified fluid pressure.

An energy storage device for storing energy generated from operation of a work vehicle includes a ballast providing ballast weight to the work vehicle, a stator of an electric machine mounted on the work vehicle, a rotor of the electric machine fixed for rotation with the ballast, spaced from the stator by a gap, and configured for rotation relative to the stator such that the electric machine is configured to generate electrical current from rotation of the rotor and the ballast relative to the stator and to rotate the rotor and the ballast from electrical current received by the electric machine, and a gap modulator coupled to at least one of the stator and the rotor and configured to selectively adjust the gap between the rotor and the stator based on an operation of the electric machine.

A working vehicle includes a vehicle body to be coupled to a working device, a communication controller to obtain first operation information relating to operation of the working device, the communication controller being electrically connected to the working device to communicate bi-directionally with the working device, an applicability judging device to judge applicability of the working device to the operation based on the first operation information obtained by the communication controller, and a display device to display the applicability judged by the applicability judging part.

A travel control system includes a permission unit that permits outermost periphery automatic traveling if predetermined permission conditions are satisfied. The permission conditions include a first condition and a second condition. The first condition is that a reference value corresponding to a working width W1 of a work device 30 is larger than a lateral width W2 of the work device. The second condition is that the reference value is larger than a threshold value determined by a threshold value determination unit. The threshold value determination unit determines the threshold value based on a reference distance D1 between a front end position of a work vehicle 1 and a reference position SP at which the work device 30 is switched from a working state to a non-working state.

The purpose of the present invention is to improve visibility of a status display unit while simplifying the installation of the status display unit and preventing damage to the status display unit. The present invention comprises: a work vehicle body capable of traveling automatically; a status detection unit that detects the status of the work vehicle body; and status display units that show a status display according to the status of the work vehicle body detected by the status detection unit. At least one pair of status display units are arranged diagonally across the work vehicle body in plan view.
