The pre-fuel filter 6100 is attached to the right side step 3000.

More specifically, the pre-fuel filter 6100 is joined to the right side step 3000 with the bolt 6101 and the bolt hole 3005, into which this is screwed, used.

It is desirable that the main fuel filter 6200 be attached, directly or indirectly, to at least one of the vehicle side attaching frame 1100 and the right side step 3000.

In the present embodiment, the main fuel filter 6200 is attached to the fuel filter cover holding frame 6210 which is attached to the vehicle side attaching frame 1100.

Since, by attaching/detaching the vehicle side attaching frame 1100 to/from the frame body a, the right side step 3000, the pre-fuel filter 6100, the main fuel filter 6200 and the fuel filter cover holding frame 6210 can be integrally attached to or detached from the vehicle main body 1000, the maintenance becomes easy.

And, the fuel filter cover 6300 is attached to the fuel filter cover holding frame 6210.

More specifically, the upside of the fuel filter cover holding frame 6210 is joined to the vehicle side attaching frame 1100 with the welding part 6211 used, and the downside of the fuel filter cover holding frame 6210 is joined also to the right side step 3000 with the welding part 6212 used as well.

Further, the front side of the fuel filter cover 6300 is joined to the fuel filter cover holding 6302 and 6303, and frame 6210 with the bolts 6301, the bolt holes 6213, 6214 and 6215, into which these are screwed, used, and the rear side of the fuel filter cover 6300 is joined also to the right side step 3000 with the bolts 6304 and 6305, and the bolt holes 3003 and 3004, into which these are screwed, used as well.

Furthermore, the fuel filter cover 6300 possesses the fuel filter cover lower part plate 6320 which can be allowed, by unfastening the butterfly nuts 6321 and 6322, to slide with respect to the left-and-right direction that is shown by the bidirectional arrow Y.

In case a configuration is adopted in which the fuel filter cover lower part plate 6320 that can be allowed to slide is provided, the maintenance of the pre-fuel filter 6100 and the main fuel filter 6200 is easily implemented, and the convenience can be improved.

Additionally, the fuel filter cover 6300 is an example of the cover of the present invention.

In addition, the fuel filter cover holding frame 6210 is an example of the cover holding frame of the present invention.

In the above, detailed descriptions have been given regarding the configuration and action of the tractor of the present embodiment.

Now, if the one or more fuel filters (the pre- fuel filter 6100 and the main fuel filter 6200) are arranged at a front side of the right side substep (the right side step 3000) as described above, with vacant space being exploited, the plural fuel filters become able to be attached.

However, the size of the vacant space like that is limited.

Hereupon, the present inventors consider that. in order to amply exploit the vacant space, it is necessary to further push on with the reduction of the number of components in the configuration of the neighborhood of the pre-fuel filter 6100 and the main fuel filter 6200.

Hereupon, in what follows, specific descriptions are given regarding the reduction of the number of components in the configuration of the neighborhood of the pre-fuel filter 6100 and the main fuel filter 6200. (1) A configuration is considered in which a filter stay for joining, with the bolt 6101 and the bolt hole 3005, into which this is screwed, used, the pre-fuel filter 6100 to the right side step 3000 is provided integrally with the right side step 3000.

For example, bolt holes into which bolts for attaching the filter stay to the right side step 3000 are screwed may be, in such a way that the position of the pre-fuel filter 6100 can be adjusted with respect to the up-and-down direction which is shown by the bidirectional arrow Z, provided at two or more spots of the right side step 3000 regarding the up-and-down direction.

Of course, it goes without saying that, corresponding to this, bolt holes into which bolts for attaching the main fuel filter 6200 to a plate are screwed may be provided at two or more spots of the plate regarding the up-and-down direction, in such a way that the position of the main fuel filter 6200 can be adjusted with respect to the up-and-down direction, with the size of the plate for attaching the main fuel filter 6200 to the fuel filter cover holding frame 6210 which is joined to the vehicle side attaching frame 1100 with the welding part 6211 used being allowed to be larger with respect to the up-and-down direction.

Then, for example, since by adjusting the attaching positions of the pre-fuel filter 6100 and the main fuel filter 6200 the heights of these can be changed, the raising amount of the mower deck which is installed between the front wheels and the rear wheels becomes able to be sufficiently ensured. (2) A configuration is considered in which the fuel filter cover 6300 is provided integrally with the right side step 3000.

For example, the fuel filter cover 6300 may be configured so as to be divided into the fuel filter cover lower part plate 6320 and a base part as a filter bracket which is integrated with the right side step 3000, in such a way that the fuel filter cover lower part plate 6320 can be allowed, by unfastening the butterfly nuts 6321 and 6322, to slide with respect to the left-and-right direction which is shown by the bidirectional arrow Y.

Then, for example, since the fuel filter cover lower part plate 6320 can be allowed to slide and detached even if the base part is integrated with the right side step 3000, the maintenance of the pre-fuel filter 6100 and the main fuel filter 6200 becomes able to be implemented with ease through the opening part of the downside, as being described above.

Of course, it goes without saying that at the base part, the front loader oil pressure hose attaching part 6310 and so forth may be provided.

A vehicle in the present invention is able to realize attachment of one or more fuel filters to a location other than the engine, and is useful for an objective of utilization as a work vehicle and so forth like a vehicle for agriculture such as a tractor and so forth.
