Abstract

A working vehicle includes an inertia detector to measure inertia information of a vehicle body, a rear axle supporting a rear wheel, and a transmission case rotatably supporting the rear wheel. The inertia detector overlaps with at least a portion of the transmission case in a plan view and is capable of accurately measuring inertia information when a vehicle body changes attitude.

First claim

What is claimed is:

1. A tractor comprising:
an inertia detector to measure inertia information of a vehicle body;
a right rear wheel;
a left rear wheel;
a transmission case of the vehicle body to transmit a driving force to the right rear wheel and the left rear wheel; and
a rigid portion including a pair of vehicle frames; wherein
one of the pair of vehicle frames is located at a right side of the transmission case, and the other one of the pair of vehicle frames is located at a left side of the transmission case; and
the inertia detector is provided at a position adjacent to the rigid portion including the pair of vehicle frames and located in a space between the pair of vehicle frames.

2. The tractor according to claim 1 , further comprising:
a first fender covering an upper portion of the right rear wheel; and
a second fender covering an upper portion of the left rear wheel; wherein
the inertia detector is at a middle position between the first and second fenders in a front view.

3. The tractor according to claim 1 , wherein the inertia detector overlaps with at least a portion of the right and left rear wheels in a side view.

4. The tractor according to claim 1 , wherein the inertia detector is fixed and housed in a mud-guard case.
