Abstract

In the work vehicle, a pair of left and right fuel tanks is distributed into left and right sides of a traveling body. A tank support plate to support the fuel tanks from below is made up of a pair of front and rear transverse frames extended leftward and rightward below the left and right rear frames, and a pair of left and right tank mounting plates on which the front and rear transverse frames are held in a back-and-forth direction on both left and right sides. The left and right fuel tanks are respectively mounted and secured onto the left and right tank mounting plates. A support mount and the front transverse frame are coupled to each other by a coupling bracket.

First claim

What is claimed is:

1. A work vehicle comprising:
an engine serving as a driving source;
a traveling section configured to drive on a basis of power of the engine; and
a transmission section configured to transmit the power of the engine to the traveling section,
wherein a traveling body is configured by coupling left and right front frames and left and right rear frames in a back-and-forth direction, and an operator's seat is supported on the traveling body with a support mount interposed therebetween,
wherein a pair of left and right fuel tanks are distributed into left and right sides of the traveling body, a tank support plate to support the fuel tanks from below is made up of a pair of front and rear transverse frames extended leftward and rightward below the left and right rear frames and a pair of left and right tank mounting plates on which the front and rear transverse frames are held in the back-and-forth direction on both left and right sides, and the left and right fuel tanks are respectively mounted and secured onto the left and right tank mounting plates, and
wherein the support mount and the front transverse frame are coupled to each other by a coupling bracket.

2. The work vehicle according to claim 1 ,
wherein a front end of each of the left and right rear frames is held by a beam frame, and a rear end of each of the left and right rear frames is coupled to left and right side surfaces of the transmission section, and the traveling body is supported by the traveling section with the transmission section interposed therebetween, and
wherein each of the front and rear transverse frames is secured in a hanging manner by being fastened to a lower surface of the beam frame and a lower surface of the transmission section.

3. The work vehicle according to claim 1 ,
wherein the left and right fuel tanks are fuel tanks having different capacities, and an oil separator to separate water from a fuel in the fuel tanks is mounted on a first tank mounting plate with a first fuel tank having a small capacity mounted thereon, and
wherein the oil separator is mounted at a front position of the first fuel tank on the first tank mounting plate.

4. The work vehicle according to claim 1 , wherein a step for getting on and off the operator's seat is coupled to one end of the front transverse frame being coupled to the support mount.

5. The work vehicle according to claim 1 , wherein a battery is supported on one end of the front transverse frame.

6. The work vehicle according to claim 5 , wherein an operator's seat is supported by an upper part of the traveling body with front support mounts interposed therebetween, a battery case of the battery is supported by the coupling bracket being coupled to one of the front support mounts of the support mounts, and the battery is accommodated in the battery case.

7. The work vehicle according to claim 5 , wherein a step for getting on and off the operator's seat is disposed at lower left and right parts of the operator's seat, and a part of the step is supported by the front transverse frame.
