BULLDOZER EQUIPMENT

PROBLEM TO BE SOLVED: To provide bulldozer equipment capable of reducing the whole length of a vertical shaft and a fore-and-aft shaft and reducing the dimension in the vertical direction from the fore-and-aft shaft to a tilt cylinder while ensuring sufficient strength of the shafts to constitute a structure on a rear surface side of a blade into a compact configuration. 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 supporting body 4 supports the fore-and-aft shaft Z in front of a lower part of the vertical shaft Y, and the tilt cylinder S3 is arranged in front of an upper part of the vertical shaft Y and above the fore-and-aft shaft Z.
