摘要： A blade mounting structure of a bulldozer capable of enhancing visibility and operability of a blade is provided. A left portion and a right portion of a blade and a vehicle main body are swingably connected with a set of left and right straight frames. The straight frames and the blade are swingably connected respectively by a hydraulic cylinder and a support member. The blade mounting structure includes an arm for connecting a single one of the straight frames and the blade to be swingable up and down and to the left and the right. A connecting point of the arm and the blade is provided on an axis line connecting horizontal axes of rotation of connecting points of the set of left and right straight frames and the blade in plane view.

摘要： A blade has an overall blade width of W, and includes a central front portion, interposition front portions, and side front portions. A straight first edge section is arranged on the lower end of the central front portion. Each of the front surfaces of the central front portion, the interposition front portions, and the side front portions is formed in an arc-shaped surface that has a prescribed radius R2. The radius R2 satisfies the following formula: R2=(0.7 to 1.0)×H, where H is the height from the edge of the first edge section to the top end of a soil retaining plate in side view in a digging posture when the edge angle α of the edge sections is an angle of 40° to 55°.
