Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tractor which is convenient for transportation and storage.

[0002]

2. Description of the Related Art When transporting a tractor, the tractor is long in the front and rear. Therefore, after removing the front wheels and the rear wheels, two tractors A are tilted with respect to the container 99 as shown in FIG. 16, for example. Each of them was packed 98, and three of them were lined up in the front and back to form a two-tiered stack, and a total of 12 tractors A were stored in the container 99 and transported.

[0003]

Therefore, in the conventional case, since the tractor is long in the front and rear, the number of units loaded in the container is greatly limited, and it is inconvenient to transport and store the tractor. In view of the above problems, the present invention makes it possible to shorten the front and rear lengths of a tractor by a simple disassembling operation, thereby facilitating transportation and the like.

[0004]

The technical means of the present invention for solving this technical problem is to provide the front axle frame 2 with:
In the tractor to which the steering arm 23 connecting the tie rods 25 and the steering booster 26 are attached, the front axle frame 2 is configured to be divided into a frame body 19 and a frame front portion 20, and The steering arm 23 and the steering booster 26 are attached so as to be retractable so as not to project to the frame front portion 20 side.

[0005]

When transporting the tractor, by removing the frame front portion 20 of the front axle frame 2 from the frame body 19, the front and rear length of the tractor can be shortened by a simple disassembling work. As shown in the drawing, the tractors A can be packed 98 one by one and arranged laterally with respect to the container 99, and eight tractors A can be arranged in the front-rear direction to be stacked in two stages. Therefore, a total of 16 tractors A can be compactly stored in the container 99. Moreover, at this time, since the steering booster 26 and the like can be housed in the frame body 19 without being removed, pipes and the like related to hydraulic pressure do not have to be removed from the tractor A.
