等という極めて有用な新規的効果を奏するものである。In summary, according to the present invention, a front dozer including a blade, a dozer arm, a dozer cylinder and the like is provided in front of a machine frame, and an operating lever of the front dozer is arranged near a driver's seat. In the machine, the main transmission lever and the position control lever are centrally arranged on one side of the driver's seat, and the front dozer is located at a position located in front of the front most tilted position of each lever and substantially in the center between the levers. Since the operation levers are installed, various levers are centrally arranged on one side of the driver's seat, but the lever group related to the operation of the machine body and the operation lever of the front dozer are limited to a limited space. Can be used to place the image at a position where it can be visually and intuitively recognized. Further, since the grips of the operation levers are positioned higher than the grips of the other lever groups, only the operation levers of the front dozer project upward, so that even if the levers are centrally arranged, the operation levers are concentrated. It is possible to correctly and smoothly use the operation related to the aircraft and the lever operation of the front dozer without inducing mistaken operation. And the like, which are extremely useful new effects.
