PURPOSE: To increase controllability by comparing an effective pressing force detected during snow removal and a cutting angle with their target values, respectively, and correcting actuators.
CONSTITUTION: A work mode according to pressed snow condition is selected, and an objective values of a vehicle speed response pressing pressure and an edge wear amount response cutting angle are set, respectively. Next, a cutting angle is detected by a stroke sensor 7, compared with the objective value, and a corrected instruction signal is output. A height is detected by a stroke sensor 6, and a corrected instruction signal is output with a new product edge ground- contact height as a reference value. Then an effective pressing pressure is detected by a pressure sensor 5, and a corrected instruction signal is output so that an objective value according to the vehicle speed can be obtained. In addition, the cutting angle during traveling is compared with the objective value corresponding to the edge wear amount, and the corrected instruction signal is output. Also positions, angles, pressing forces, etc., in characterized blade form are displayed on a color liquid crystal monitor 29 of a display section. Thus, the objective values corresponding to the pressed snow conditions are automatically set and controlled to work efficiently, safely, and accurately.
