<P>PROBLEM TO BE SOLVED: To provide bulldozer equipment capable of securely supporting not only an outer end part of a blade but also an intermediate part of it by a supporting body. Ž<P>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, the 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 longitudinal shaft Z. The supporting body 4 has a sliding part 4B facing the blade 5 at a tip of an arm part 4A protruding outward in the right and left directions. A guide member 6 is provided on a rear surface of the blade 5 and regulates the movement of the blade 5 leaving a front part while allowing the blade 5 to swing vertically. This guide member 6 has an outer periphery guide member 6A engaging with an outer periphery side of the sliding part 4B in the radial direction of the longitudinal shaft Z and an inner periphery guide member 6B engaging with an inner periphery side of the sliding part 4B.
