Claim Text:
1. A snow removal machine including a travel unit frame having a travel unit mounted thereon, and an auger housing having an auger housed therein and not only liftable and lowerable but also rollable relative to the travel unit frame, the snow removal machine comprising: a frame inclination angle detection section for detecting an inclination angle of the travel frame itself relative to a ground surface with which the travel unit is contacting; a housing inclination angle detection section for detecting an inclination angle of the auger housing relative to the travel unit frame; and an overall inclination angle evaluation section for evaluating an overall inclination angle of the auger housing relative to the ground surface on the basis of the inclination angle detected by the frame inclination angle detection section and the inclination angle detected by the housing inclination angle detection section, wherein the frame inclination angle detection section and the housing inclination angle detection section being provided on a part of the snow removal machine which does not make rolling motion together with the auger housing, and wherein the overall inclination angle evaluation section has a filter function that, upon determination that the snow removal machine is traveling at an accelerating or decelerating speed or making a turn, slowly changes a value of the inclination angle detected by the frame inclination angle detection section.
