Abstract

The present invention is a work vehicle having a first operation tool which is rockable or movable in a front/back direction arranged on a one side of a driver's seat. A second operation tool is rockable or movable in the front/back direction and is arranged forward of the first operation tool. A third operation tool is depressible and is arranged between the first operation tool and the second operation tool in the front/back direction.

First claim

What is claimed is:

1. A work vehicle, comprising:
a driver's seat;
a first operation tool which is rockable in a front/back direction and arranged on one of a left side and a right side of the driver's seat;
a second operation tool which is rockable in the front/back direction and arranged forward of the first operation tool; and
a third operation tool which is depressible and arranged between the first operation tool and the second operation tool in the front/back direction,
wherein the third operation tool is located below an upper end of both the first operation tool and the second operation tool, and
wherein the third operation tool is located forward of the first operation tool even when the first operation tool is in a forward position.

2. The work vehicle according to claim 1 , wherein the first operation tool, the second operation tool, and the third operation tool operate at least one work apparatus.

3. The work vehicle according to claim 1 , wherein the third operation tool is a PTO clutch operation tool which disengages/engages power transmitted to a PTO shaft.

4. The work vehicle according to claim 1 , wherein the second operation tool is a front loader operation tool which is rockable in both the front/back direction and a right/left direction, and operates a front loader.

5. The work vehicle according to claim 1 , wherein:
the first operation tool comprises a user grippable first grip arranged at a position higher than the third operation tool; and
the second operation tool comprises a user grippable second grip arranged at a position higher than the first operation tool and the third operation tool.

6. The work vehicle according to claim 1 , wherein the work vehicle is a tractor.

7. The work vehicle according to claim 1 , wherein the first operation tool is located more rearward than a front end of the driver's seat and the second operation tool is located more forward than the front end of the driver's seat.

8. The work vehicle according to claim 7 , wherein the upper end of the first operation tool is located below the upper end of the second operation tool.

9. A work vehicle, comprising:
a driver's seat;
a first operation tool which is rockable in a front/back direction and arranged on one of a left side and a right side of the driver's seat;
a second operation tool which is rockable in the front/back direction and arranged forward of the first operation tool; and
a third operation tool which is depressible and arranged between the first operation tool and the second operation tool in the front/back direction,
wherein the third operation tool is located below an upper end of both the first operation tool and the second operation tool, and
wherein the first operation tool is a PTO speed change operation tool adapted to change a speed of a PTO shaft.

10. A work vehicle, comprising:
a driver's seat;
a first operation tool which is rockable or movable in a front/back direction and arranged on one of a left side and a right side of the driver's seat;
a second operation tool which is rockable or movable in the front/back direction and arranged on one of the left side and the right side of the driver's seat; and
a third operation tool which is depressible and arranged on one of the left side and the right side of the driver's seat;
wherein:
the first operation tool comprises a first grip arranged at a position higher than the third operation tool; and
the second operation tool comprises a second grip arranged at a position higher than the first operation tool and the third operation tool, and

wherein an upper end the third operation tool is located below an upper end of both the first operation tool and the second operation tool, and
wherein the third operation tool is located forward of the first operation tool even when the first operation tool is in a forward position.

11. The work vehicle according to claim 10 , wherein the first operation tool, the second operation tool, and the third operation tool operate at least one work apparatus.

12. The work vehicle according to claim 10 , wherein the third operation tool is a PTO clutch operation tool which disengages/engages power transmitted to a PTO shaft.

13. The work vehicle according to claim 10 , wherein the second operation tool is a front loader operation tool which is rockable in the front/back direction and the right/left direction and operates a front loader.

14. The work vehicle according to claim 10 , wherein the work vehicle is a tractor.

15. A work vehicle, comprising:
a driver's seat;
a first operation tool which is rockable or movable in a front/back direction and arranged on one of a left side and a right side of the driver's seat;
a second operation tool which is rockable or movable in the front/back direction and arranged on one of the left side and the right side of the driver's seat; and
