Abstract

A working vehicle includes an operator's seat, a vehicle body to travel selectively using either manual steering performed manually by the operator or automatic steering performed based on a position of the vehicle body detected by a position detector without manual operation by the operator, and a first operation actuator on a lateral side of the operator's seat to selectively start or terminate the automatic steering during rearward traveling of the vehicle body or to correct the position of the vehicle body during rearward traveling of the vehicle body.

First claim

What is claimed is:

1. A working vehicle, comprising:
an operator's seat on which an operator sits;
a steering wheel provided in front of the operator's seat;
a steering column provided below the steering wheel;
a vehicle body to travel selectively using either manual steering performed manually by the operator or automatic steering performed based on a position of the vehicle body detected by a position detector without manual operation by the operator;
a first operation actuator on a lateral side of the operator's seat to selectively start or terminate the automatic steering during rearward traveling of the vehicle body or to correct the position of the vehicle body during rearward traveling of the vehicle body; and
a second operation actuator to perform an operation relating to the automatic steering and operable to selectively start or terminate the automatic steering during rearward traveling of the vehicle body or to correct the position of the vehicle body during rearward traveling of the vehicle body; wherein
the first operation actuator is rearward relative to a front end of the operator's seat and forward relative to a rear end of the operator's seat; and
the second operation actuator is disposed on the steering column.

2. The working vehicle according to claim 1 , further comprising:
a console on the lateral side of the operator's seat; and
an armrest between the console and the operator's seat; wherein
the console:
includes a front portion positioned outward of the steering wheel in a vehicle width direction, and a rear portion positioned outward of a rear portion of the operator's seat in the vehicle width direction; and
is located next to the armrest in the vehicle width direction; and

the first operation actuator is on an upper portion of the console and at a position higher than the armrest.

3. The working vehicle according to claim 2 , wherein the first operation actuator is disposed outward in the vehicle width direction from a fore-and-aft central portion of the armrest or a vicinity thereof and is disposed at a fore-and-aft central portion of the console or a vicinity thereof.

4. The working vehicle according to claim 1 , wherein
the first operation actuator is positioned outward of a fore-and-aft central portion of a seat portion in a vehicle width direction or in a vicinity thereof; and
the seat portion is a portion of the operator's seat on which the operator is to sit.

5. The working vehicle according to claim 1 , wherein the second operation actuator is on an opposite side of a central portion of the operator's seat relative to the first operation actuator.

6. The working vehicle according to claim 1 , wherein the first operation actuator is operable to selectively start or terminate the automatic steering during forward traveling of the vehicle body or to correct the position of the vehicle body during forward traveling of the vehicle body.
