摘要： A snow plow includes a control unit for controlling a raising/lowering drive mechanism so that an auger housing becomes horizontal, a relative angle detection unit for detecting the angle of the auger housing relative to a travel frame, and a horizontal detection unit for detecting the horizontal state of the auger housing. The control unit stops the raising/lowering drive mechanism when the control unit assess that either a first condition or a second condition is satisfied, the first condition being that the relative angle be zero and the second condition being that the auger housing be horizontal.

摘要： Walk-behind power equipment includes: a main body including front and rear wheels; a work unit provided on the main body; a work motor that drives the work unit; a travel motor that rotates the rear wheel; a handle extending from the main body rearward and upward; a posture detector that detects a rearward tilted state of the main body in which the rear wheel is in contact with a ground and the front wheel is not; and a control unit that drive-controls the work motor and travel motor, wherein when the main body is in the rearward tilted state, the control unit causes a rotational speed of the travel motor to be reduced compared to when the front wheel is in contact with the ground, or causes a rotational speed of the work motor to be reduced compared to when the front wheel is in contact with the ground.

The machine also includes: a frame inclination angle detection section for detecting an inclination angle of the travel frame relative to a ground surface; 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 angles detected by the two detection sections. The two detection sections are provided on a part of the machine which does not make rolling motion together with the auger housing.

摘要： A snow removal machine has: a storage unit that stores a vehicle speed coefficient map indicating the relationship between an incline angle and a vehicle speed coefficient for decreasing an instructed vehicle speed; a vehicle speed coefficient setting unit that sets the vehicle speed coefficient on the basis of a detected incline angle and the vehicle speed coefficient map; and a vehicle speed setting unit that sets the vehicle speed of a traveling unit by way of multiplying the instructed vehicle speed by the set vehicle speed coefficient. The vehicle speed coefficient map sets the vehicle speed coefficient so same is smaller for larger incline angles when at least the traveling unit is going forward on an upslope. A travel control unit controls a drive source so that the traveling unit travels at the set vehicle speed set by the vehicle speed setting unit.
