A device and method operated thereby may control a hydraulic pump to pump a hydraulic fluid into a chamber of a piston coupled to a fifth wheel of the tractor to raise the fifth wheel. The device, and method operated thereby, may sense, at intervals as the fifth wheel rises, a pressure value of the hydraulic fluid in the chamber. The device, and method operated thereby, may process the pressure values to determine when the landing gear is lifted off the ground.

A multipurpose work vehicle according to one or more embodiments of the present invention includes a driver's seat at the center of a vehicle body in the left-right direction of the vehicle body; and an occupant's seat to the left or right of the driver's seat in the left-right direction of the vehicle body, wherein the occupant's seat is offset rearwardly relative to the driver's seat.

A working vehicle includes a position detector to detect a position of a vehicle body based on a signal transmitted from a positioning satellite. A mounting stay pivotally supported by a base stay includes a counter surface that opposes an upper surface of the base stay when the position detector is in a first position. The position detector is movable from the first position to a second position according to rotation of the mounting stay causing the counter surface to face upward. When the position detector is in the second position, a front portion of the mounting stay is higher than an upper end of the roof and a rear portion of the mounting stay is lower than the upper end of the roof.

A tractor in which a lift valve of a hydraulic system for lifting up/down a work machine is mechanically coupled to a lift lever, and conditions for an engine startup are set as follows: a reverser lever is at a neutral position thereof; a PTO (power take-off) clutch is disengaged; a seat switch is ON; and the lift lever is at a lowermost position thereof. A switch driving unit is provided on a side face of the lift lever so that the side face is orthogonal to a turning direction of the lift lever; a switch is provided so as to be opposed to the switch driving unit when the lift lever is turned to be at the lowermost position; and the lift lever at the lowermost position is detected by the switch.

An objective is to appropriately position a communication module that carries out wireless communication to exchange information regarding cooperative travel with another vehicle, in order to simplify the measures that are to be taken to avoid thermal damage, and prevent antenna cables from being damaged, for example. A work vehicle includes: a cabin 4 in which a boarding space is formed; and an electronic control system for automatic driving through which a vehicle body is automatically driven. The electronic control system includes a positioning unit that measures the position and orientation of the vehicle body, and a cooperation control unit that causes the vehicle body to automatically travel in cooperation with another vehicle. The cabin 4 is provided with a roof 62 that provides a storage space 62A that is surrounded by an inner roof 101 and an outer roof 102. The cooperation control unit includes a communication module 71 that wirelessly communicates with another vehicle to exchange information regarding cooperative travel with the other vehicle, including vehicle body position information. Antennas of the communication module 71 are provided on an upper end portion of the cabin 4, and a communication information processing apparatus 122 of the communication module 71 is provided in the storage space 62A.

An agricultural tractor including a chassis having a front end and a rear end, the chassis defining a longitudinal axis; a first axle; a second axle; a hood which substantially encloses an engine compartment; and a cab. The first axle and the hood are proximate the front end of the chassis and the second axle and the cab are proximate the rear end of the chassis. The hood and cab are positioned above the chassis, and the cab and chassis are fixed relative to each other and longitudinally spaced apart on the chassis.

A rolling soil probe which may be pulled by a tractor or a truck or mounted on a trailer. The rolling soil probe includes a rotatable square wheel having four sides, each of which has a soil probe extending outwardly therefrom.
