摘要： A snow conversion system for removal of snow from an access surface includes a mixing tank and a conveyor apparatus fluidly connected to the mixing tank for transferring the snow from the access surface into the mixing tank. The system also includes a fluid delivery arrangement for injecting a chemical agent into the mixing tank to combine the chemical agent with the transferred snow and thereby generate a solution of the melted snow and the chemical agent. The system additionally includes a mixer for agitating and mixing the snow and the injected chemical agent in the mixing tank to thereby further facilitate melting of the snow in the mixing tank. The system further includes a fluid nozzle in fluid communication with the mixing tank for dispensing the solution of the melted snow and the chemical agent onto the access surface to thereby provide de-icing and/or anti-icing of the access surface.

摘要： A snow removal device may include an engine assembly operably coupled at least in part to a frame of the snow removal device. The snow removal device may further include a mobility assembly operably coupled to the frame and the engine assembly to provide mobility of the snow removal device responsive at least in part to operation of the engine assembly. The snow removal device may even further include an ejection assembly that includes a chute for ejecting material from the snow removal device, and a handle assembly that includes a lever assembly. Moreover, the snow removal device may also include a chute rotation assembly operably coupled to the chute of the ejection assembly. The chute rotation assembly may include a cable system, the cable system operably coupling the lever assembly to the chute rotation assembly. The chute rotation assembly may also include a disc clutch assembly configured to move between an engaged position and a disengaged position in response to actuation of the lever assembly, where when the disc clutch assembly is in the disengaged position, the chute is enabled to rotate between a plurality of positions.

摘要： Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.

摘要： A snow blower including an auger housing, an auger rotatably positioned within the auger housing and configured to blow snow, a shaft attached to the auger and the auger housing, a chute attached to the auger housing and configured to direct the snow blown by the auger away from the snow blower, and at least one sensor configured to detect at least one of a rotational speed of the auger or the shaft and a load, torque, and/or thrust on the shaft or the auger housing. The data collected by the at least one sensor is used to determine an instantaneous flow rate of snow.

摘要： Walk-behind power equipment includes: a main body provided with at least one front wheel and left and right rear wheels and a work unit; travel motors provided for the respective rear wheels; a handle extending from the main body rearward and upward; at least one of a tilt angle detector that detects a tilt angle of the main body and a load detector that detects a downward load applied to the handle; a yaw rate detector that detects a yaw rate; and a control unit that drive-controls the travel motors. The control unit determines whether the main body is in a rearward tilted state based on the tilt angle or the downward load, and if it is determined that the main body is not in the rearward tilted state, performs straight-line travel control to set a rotational speed difference between the travel motors to reduce the yaw rate.
