Claim:
A dozer apparatus comprising: a dozer frame supported to a traveling machine body to be pivotable about a horizontal shaft, the dozer frame being vertically movable by a dozer cylinder; a support body supported to the dozer frame to be pivotable about a vertical shaft, the support body being pivotable in a fore/aft direction by an angle cylinder; and a blade supported to the support body to be pivotable about a fore/aft shaft, the blade being vertically pivotable by a tilt cylinder; the support body supporting the fore/aft shaft downwardly and forwardly of the vertical shaft; and the tilt cylinder being disposed upwardly and forwardly of the vertical shaft and also upwardly of the fore/aft shaft, wherein the support body includes arm portions projecting outward in a right/left direction and a sliding portion provided at the leading end of each arm portion and facing the blade; in a rear face of the blade there is provided a guide member that restricts forward departing movement of the blade while allowing vertical pivoting movement of the blade relative to the sliding portion; the fore/aft shaft has an axis set lower than a vertical center of the sliding portion; the guide member includes an outer peripheral guide element engageable with an outer peripheral part of the sliding portion in a radial direction of the fore/aft shaft and an inner peripheral guide element engageable with an inner peripheral part of the sliding portion; and the inner peripheral guide element is disposed at such a position relative to the blade that the inner peripheral guide element becomes exposed from the support body to be attachable/detachable when the tilt cylinder is detached and the blade is vertically pivoted about
