Abstract: A work vehicle includes a cutter device for cutting plant in a field, a storage section for storing plant cut by the cutter device, an inclination angle sensor for detecting an inclination angle ((?d)) of the vehicle body, a display device for displaying the inclination angle detected by the inclination angle sensor, and a reporting device for reporting the inclination angle exceeding a permissible inclination angle ((?a)).

Abstract: An off-road vehicle that travels on the off-road ground includes: a sensor group configured to detect unevenness of the ground; a camera configured to capture the unevenness of the ground; a ground unevenness degree calculation unit configured to calculate a ground unevenness degree indicating an unevenness degree of the ground based on an input parameter; an input parameter setting unit configured to set, as the input parameter, data selected from among data detected by the sensor group and image data captured by the camera; an unevenness-position data generation unit configured to associate the actual vehicle position with the ground unevenness degree to generate ground unevenness-position data; and a data storage unit configured to store the ground unevenness-position data.

Abstract: A work vehicle includes an imaging device for imaging a plant growing in a field and a control device for controlling a sowing device. The control device includes a growth state determination section for determining a growth state of the plant in the field based on result of imaging by the imaging device and a sowing instruction section for instructing the sowing device to carry out a seed sowing operation based on result of determination of the growth state determination section.

Abstract: A work vehicle includes: a seat disposed between front wheels and rear wheels; an engine disposed between the right and left rear wheels rearward of the seat; a battery disposed in a container space positioned downward of the seat disposed frontward of the rear wheels; an air cleaner disposed in the container space and arranged proximally to the battery in a vehicle longitudinal direction; and an opening-closing lid unit for covering the air cleaner and the battery from outside in a vehicle transverse direction. An element of the air cleaner is disposed in the air cleaner so that the element is insertable and removable in the vehicle transverse direction, and a position of the air cleaner is set so that the element is accessible from outside the vehicle body.
