PROBLEM TO BE SOLVED: To increase the work amount in a low cost by installing a bar-like weight of metal material along the longitudinal direction in the hollow interior of a working machine support frame in a working machine apparatus of a working vehicle supporting a working machine by a working machine support frame. SOLUTION: A bulldozer 10 includes an earth removal device 20 at the front, and a ripper device 30 at the back. The earth removing device 20 includes a blade 23 as a working machine, and each one end of blade support frames 21a, 21b is connected to the lower parts of both ends in the lateral direction of a vehicle of the blade 23. A bar-like weight is installed as a weight for adjusting the weight extending over the longitudinal direction of the hollow interior of the support frames 21a, 21b. A ripper support frame 31 supporting the ripper 32 is also provided with a bar-like weight extending over the longitudinal direction of the hollow interior. Thus, the weight of the bulldozer is increased to adjust the position of center of gravity, so that the earth removal device 20 is increased in its biting amount to the earth, and further the ripper device 30 is increased in drilling depth so as to increase the work amount.
