Description

  The present invention relates to an agricultural vehicle such as a tractor, and more particularly to an auxiliary device that improves workability during refueling and that can provide good boarding / exiting performance.

  Generally, in an agricultural vehicle such as a tractor, when refueling a fuel tank, a fuel tank such as a poly tank is placed in the vicinity of a fuel filler port, and fuel is supplied using a manual or electric pump. However, in an agricultural vehicle that has a fuel filler opening at the upper part of the fuselage (for example, the upper part of the bonnet) and the placement space for the fuel tank is not secured, the fuel tank is placed at the upper part of the fuselage to supply fuel. Not only is it difficult to stably support the hood, but it also has the disadvantage of scratching the bonnet.

In view of this, it has been proposed to provide a fueling auxiliary base in which a fueling tank can be placed in the vicinity of the fueling port (see, for example, Patent Documents 1 to 4). With this configuration, the oil tank can be stably supported during refueling, so that not only the workability of refueling is improved, but also the inconvenience of damaging the bonnet or the like can be avoided.
