Abstract

There is configured a work machine whose engine and fuel tank will not be damaged at time of a work even when the engine and the fuel tank are arranged with offset to one side in the left/right direction of the machine body. The work machine includes a machine body that can travel with left and right front wheels and left and right rear wheels and an implement supported to the machine body. An engine driving the front wheels, the rear wheels and the implement and a fuel tank are disposed between the front wheels and the rear wheels in a front/rear direction of the machine body and at positions offset to further outer side than the left/right center of the machine body. There is provided a protection member which protrudes to a further outer side than an outer end position of the fuel tank in an offset direction of the fuel tank.

First claim

The invention claimed is:

1. A work machine comprising:
a machine body that can travel with left and right front wheels and left and right rear wheels;
an implement supported to the machine body;
an oil feeding pipe which extends upwards from the outer end position of the fuel tank in the offset direction as seen in the plan view; and
a cap detachably attached to an upper end of the oil feeding pipe;
wherein an engine driving the front wheels, the rear wheels and the implement and a fuel tank reserving fuel for the engine are disposed between the front wheels and the rear wheels in a front/rear direction of the machine body and at positions offset to further outer side than the left/right center of the machine body,
wherein there is provided a protection member which protrudes to a further outer side than an outer end position of the fuel tank in an offset direction as seen in a plan view, and
wherein the protection member is disposed to protrude to the further outer side in the offset direction than an outer circumference of the cap.

2. The work machine of claim 1 , wherein as seen in the plan view, an outer end position of the protection member in the offset direction protrudes to further outer side than a virtual line which joins an outer end position of the front wheels in the offset direction and an outer end position of the rear wheels in the offset direction.

3. The work machine of claim 1 , wherein the protection member comprises a plate-like member having an arc-shaped outer edge which bulges gently at its center position in the front/rear direction as seen in the plan view.

4. A work machine comprising:
a machine body that can travel with left and right front wheels and left and right rear wheels; and
an implement supported to the machine body,
wherein an engine driving the front wheels, the rear wheels and the implement and a fuel tank reserving fuel for the engine are disposed between the front wheels and the rear wheels in a front/rear direction of the machine body and at positions offset to further outer side than the left/right center of the machine,
wherein there is provided a protection member which protrudes to a further outer side than an outer end position of the fuel tank in an offset direction as seen in a plan view, and
wherein as seen in the plan view, an outer end position of the protection member in the offset direction protrudes to further outer side than a virtual line which joins an outer end position of the front wheels in the offset direction and an outer end position of the rear wheels in the offset direction.

5. The work machine of claim 4 , wherein the protection member comprises a plate-like member having an arc-shaped outer edge which bulges gently at its center position in the front/rear direction as seen in the plan view.

6. A work machine comprising:
a machine body that can travel with left and right front wheels and left and right rear wheels; and
an implement supported to the machine body,
wherein an engine driving the front wheels, the rear wheels and the implement and a fuel tank reserving fuel for the engine are disposed between the front wheels and the rear wheels in a front/rear direction of the machine body and at positions offset to further outer side than the left/right center of the machine,
wherein there is provided a protection member which protrudes to a further outer side than an outer end position of the fuel tank in an offset direction as seen in a plan view, and
wherein the protection member comprises a plate-like member having an arc-shaped outer edge which bulges gently at its center position in the front/rear direction as seen in the plan view.
