BULLDOZER EQUIPMENT

PROBLEM TO BE SOLVED: To provide bulldozer equipment capable of transmitting telescopic force of a tilt cylinder to tilt swinging of a blade efficiently. SOLUTION: In this bulldozer equipment, a bulldozer frame 3 elevating and lowering through a bulldozer cylinder S1 is pivotally supported on a traveling machine body 2 through a horizontal shaft X, a supporting body 4 swinging forward and backward through an angle cylinder S2 is pivotally supported on the bulldozer frame 3 through a vertical shaft Y, and the blade 5 swinging vertically through a tilt cylinder S3 is pivotally supported on the supporting body 4 through a fore-and-aft shaft Z. The tilt cylinder S3 connects a tip of a cylinder rod S3a with the blade 5 above the fore-and-aft shaft Z and connects a bottom of a cylinder tube S3b with an arm part 4A being apart from the fore-and-aft shaft Z more than the cylinder rod S3a and protruding outward in the right and left directions of the supporting body 4.
