<P>PROBLEM TO BE SOLVED: To suppress pitching causing lifting of the front of a vehicle body while effectively functioning a suspension using a hydraulic cylinder when carrying out a work with a plow. <P>SOLUTION: In the draft control for ascending and descending the plow based on a traction load value detected by a traction load sensor S, the inconvenience that results from lifting the front of a running vehicle body is suppressed by allowing a mode switching means 70 to suppress or limit the suspension function by the control of a suspension control means 64 when an ascending control signal for ascending the plow is detected, and the mode switching means 70 allows a suspension mechanism to be effectively functioned by the control of the suspension control means 64 when the ascending control signal is not detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
