Abstract

A work vehicle includes a steering wheel on a rear side with respect to a display, in front of a driver seat, and that includes spokes and a ring-shaped portion connected to the spokes. An opening is between the spokes and the ring-shaped portion. The work vehicle further includes a steering controller to change a steering angle of a steerable wheel based on a wheel angle that is a rotation angle of the steering wheel about a wheel rotation shaft, and an adjuster to adjust a relationship between the wheel angle and the steering angle.

First claim

The invention claimed is:

1. A work vehicle comprising:
a driver seat;
a steerable wheel;
a display to display various types of information;
a steering wheel on a rear side with respect to the display, in front of the driver seat;
a wheel angle detector to detect a wheel angle that is a rotation angle of the steering wheel about a wheel rotation shaft;
a controller to change a steering angle of the steerable wheel based on the wheel angle; and
an adjuster to adjust a relationship between the wheel angle and the steering angle; wherein
the steering wheel includes a plurality of spokes and a ring-shaped portion that is connected to the spokes, and an opening is located between the spokes and the ring-shaped portion; and
the adjuster is configured or programmed to set, as an appropriate angle, the wheel angle that allows the display to be in a field of view from a side of the driver seat through the opening, and adjusts the relationship such that the steering angle becomes a neutral steering angle when the wheel angle is the appropriate angle.

2. The work vehicle according to claim 1 , wherein the appropriate angle is stored in advance, the adjuster is configured or programmed to read out the stored appropriate angle, and to adjust the controller based on the read appropriate angle such that the steering angle becomes the neutral steering angle.

3. The work vehicle according to claim 1 , wherein the adjuster is configured or programmed to set, as the appropriate angle, a rotation angle of the steering wheel at a point in time at which a manual operation tool to set the appropriate angle is operated, and to adjust the controller such that the steering angle becomes the neutral steering angle when the wheel angle is the appropriate angle.
