摘要： Provided is a hand-propelled working machine including a body; a traveling wheel group including wheels; a motor including a motor shaft for driving wheels to rotate; a controller; a transmission mechanism for implementing transmission between the motor shaft and the wheels and having a first state and a second state, where when the transmission mechanism is in the second state, the wheels are rotatable freely relative to the motor shaft; and an operation member operated to have at least a first operation state for controlling the motor to start and a second operation state for controlling the motor to stop; where when the operation member is switched from the first operation state to the second operation state, a target rotational speed of the motor is set to a first rotational speed so that the transmission mechanism is switched from the first state to the second state, where the first rotational speed is a negative rotational speed. The negative rotational speed is applied to the motor, achieving the shutdown and trip of the motor and a clutch and high trip reliability.

摘要： A snow thrower is provided and includes: a snow removal system and a power system configured to drive the snow removal system to work. The power system includes a first motor. The snow removal system includes a transmission shaft, an auger assembly in transmission connection with the transmission shaft, and a snow throwing impeller mounted to the transmission shaft. An output shaft of the first motor is connected with the transmission shaft directly, so that when the first motor rotates, power is transmitted to the transmission shaft through the output shaft, so as to drive the auger assembly to rotate.

摘要： A snow thrower includes a frame, a prime mover supported by the frame, and a handle assembly coupled to the frame. The handle assembly includes a grip for an operator to grasp. The snow thrower further includes an auger housing supported by the frame, and an auger blade rotationally coupled to and disposed within the auger housing. A track drive system is coupled to the frame to facilitate movement along a ground surface. The track drive system includes a drive wheel rotatably driven by the prime move, an idler wheel, and a flexible track interconnecting the drive wheel and the idler wheel. The idler wheel is moveable relative to the ground surface between and first position, in which a lowermost section of the flexible track extending between the drive wheel and the idler wheel is generally parallel to the ground surface. In the third position; a third position, in which the idler wheel is moved upwardly relative to the ground surface such that a small portion of the flexible track engages the ground surface to facilitate maneuvering the snow thrower about the drive wheel; and a fourth position, in which the idler wheel is moved downwardly relative to the ground surface such that the drive wheel is spaced away from the ground surface, to tilt the frame forward to increase an amount of snow thrower weight supported by the auger housing.

摘要： A three-stage snow thrower having a housing, a power supply , a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending between opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft for pushing loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft for pushing snow from the first stage assembly axially rearward. The third stage assembly includes an impeller that rotates to throw the snow through a chute attached to the housing to expel the snow from the housing.
