Abstract: A work vehicle includes a body including a takeoff and landing section on which an unmanned aerial vehicle is capable of taking off and landing, a travel device supporting the takeoff and landing section and capable of traveling on the ground, and a tilt acquirer configured or programmed to acquire a tilt of the takeoff and landing section from a horizontal plane, and an attitude adjustment mechanism configured to adjust an attitude of the body in accordance with the tilt acquired by the tilt acquirer such that, in a case where the tilt is equal to or more than a threshold, the attitude adjustment mechanism is operable to adjust the attitude of the body to reduce the tilt below the threshold.

Abstract: A work vehicle includes a hydraulic device and a battery. The battery is held by a lower portion of a body, below the hydraulic device and between right and left travel devices.

Abstract: A work vehicle includes: a body 1; a plurality of travel wheels 2 at front and back portions of the body 1 on each of left and right sides; a plurality of holder mechanisms A held by the body 1 and holding the respective travel wheels 2 in such a manner as to be capable of moving the travel wheels 2 independently of one another relative to the body 1; a detector B configured to detect a state of a travel surface; and a controller C configured to, based on the state that the detector B has detected, control the holder mechanisms A to move the travel wheels 2 relative to the body 1.

Abstract: A work vehicle includes a vehicle body including a loading portion that is able to load a load, drive wheels located in front and rear on both right and left sides of the vehicle body and steerable separately, a steering angle detector to detect respective orientations of the drive wheels, and a controller configured or programmed to perform drive control to drive each of the drive wheels and control to change the respective orientations of the drive wheels separately. The controller is configured or programmed such that the respective orientations of a first of the drive wheels located on one of right and left sides of the vehicle body and a second of the drive wheels located on the other of the right and left sides of the vehicle body are different from each other when the drive control is stopped.

Abstract: A work machine includes a front wheel, a rear wheel, an intermediate wheel between the front wheel and the rear wheel, and a transmission to receive a driving force from a drive source and transmit the driving force to the intermediate wheel and at least one of the front wheel or the rear wheel that is drivable as a driving wheel. The intermediate wheel has an outside diameter smaller than an outside diameter of the driving wheel.
