[0001] Cabin type agricultural vehicle [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural work vehicle, and more particularly to a cabin type agricultural work vehicle in which a driver's seat is surrounded and protected by a cabin.

In order to protect the driver's seat from the external environment and to improve the quietness and to ensure a pleasant and safe driving environment, the box-shaped cabin of transparent glass is used in the driver's seat It is widely adopted as a protection structure. This is commonly referred to as a 'cabin type farm work vehicle'.

However, the cabin type agricultural worker has difficulty in securing the visibility relative to the open type agricultural work vehicle in which the driver's seat is opened due to various components (cabin loop, front filler, rear filler, side door filler, etc.) constituting the cabin. Especially, when the loader attached to the front of the vehicle rises to the maximum, it is difficult to grasp the exact position of the loader due to the narrow field of view.

Therefore, in the conventional cabin type agricultural machine, there has been an attempt to form a cabin frame including a filler and a glass provided thereon in a curved shape to secure a wider field of view. However, in order to accomplish this, it is necessary to change the design of the cabin frame and to modify the production facility inevitably, which requires a lot of time and cost. Further, when the cabin frame is formed in a curved shape, There is a high degree of concern.
