Abstract:
A snow blower comprises a travelling device (50) having a front-wheel support shaft (4), a main frame (9) vertically rotatable around the front-wheel support shaft (4) relative to the travelling device (50), a snow-removing unit (1) disposed at a front portion of the main frame (9), and an operation unit (40) having a handle (10) provided at the rear portion of the main frame (9). The height of the snow-removing unit (1) can be adjusted by rotating the main body (9) relative to the travelling device (50). A height control lever (86) is provided near a grip of the handle (10), a latch (73) is provided at the rear portion of the main frame (9) in connection with the height control lever (86), and a lifting guide plate (72) is provided at the rear portion of the travelling device (50). A plurality of notches (72a) are formed in the lifting guide plate (72) at predetermined intervals. By operating the height control lever (86) to insert the latch (73) into selected one of the notches (72a), the main body (9) is fixed to the traveling device (50).
