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.

A material relocation device for relocation of materials includes a relocation base for the relocation of materials, and a material relocation structure connected to the relocation base for the relocation of materials towards and away from a user. The relocation structure includes a turning flap structure to be turned according to a movement direction of material relocation. The material relocation device can turn the flap structure and a counter-structure for setting the flap structure to a desired position thereof, in such a way that in a first movement direction the flap structure turns and allows the materials onto the relocation base. In a second relocation direction the flap structure closes and holds the materials on the relocation base, and when switching from the second relocation direction to the first movement direction the materials are released from the relocation base.

Disclosed is a two-stage electric powered snowblower. It has an auger, a blower, and a main drive shaft. A first electric motor is operably coupled to the drive shaft to rotate the drive shaft at a desired speed. The drive shaft is operably coupled to the auger to rotate the auger. The auger rotates to pull snow into the snowblower housing so that it can be forced out of a chute in the desired direction. A second electric motor is operably coupled to the blower to drive the blower at a desired speed which is typically higher than the speed of the auger. The second electric motor is mounted adjacent the first electric motor. The blower is operably coupled to the second electric motor. The drive shaft extends through the second electric motor the blower.

A breather device and a snow removal machine having the breather device have a casing into which blowby gas of an engine flows, an air suction port for letting out gas from the inside of the casing, and a gas-liquid separation mechanism for separating moisture contained in the blowby gas. The gas-liquid separation mechanism separates an inlet, which allows the blowby gas to flow in, and the air suction port by a predetermined distance, and has the air suction port positioned above a liquid path through which the moisture flows. A gas path allows the blowby gas to flow from the inlet to the air suction port without passing through an air cleaner element.

A snow removal apparatus operating system and a snow removal apparatus operating method capable of efficiently performing snow removal in a parking lot while reducing costs are provided. A specific parking section determination part determines a specific parking section for securing a vacant parking space according to a parking request from among parking sections recognized to have vacant parking spaces having snow accumulation if there is no parking section recognized to have a vacant parking space having no snow accumulation when a parking request recognition part recognizes the parking request. A snow removal instruction part transmits, to a snow removal apparatus, first snow removal instruction information for instructing snow removal in the specific parking section.

Provided is a snow thrower impeller assembly (24) that defines a mounting slot (84) for a wiper (70). The wiper includes a wiper portion (86) that slides into the mounting slot to mount the wiper to the impeller (54). The wiper contacts an interior wall (56) of an associated impeller housing during rotational operation of the impeller in order to limit a gap (74) between an impeller blade (66) and the interior wall. The wiper can move radially inward and outward to remain in contact with the interior wall without input from the operator. Another embodiment of the impeller assembly includes impeller blades with a first portion (116) and a second portion (118). The second portion extends at a non-zero angle from the first blade portion of the impeller blade. Methods of improving the efficiency of the snow thrower are also provided.

A snow thrower includes a motor, an auger driven by the motor to rotate, a handle device for a user to operate, an auger housing for containing the auger and a frame for connecting the handle device and the auger housing. The auger housing is made of at least two different materials.

A snow thrower is disclosed including a rotor assembly having a first auger, a second auger, and a paddle disposed between the first and second augers The snow thrower also includes an intake housing having a first interior surface adjacent to the first auger and a second interior surface adjacent to the second auger, where an outer edge of the first auger has a clearance of less than 1 centimeter from the first interior surface across a sweep of at least 120 degrees, and an outer edge of the second auger has a clearance of less than 1 centimeter from the second interior surface across a sweep of at least 120 degrees.

A method and system is disclosed which provides for a zero turn stand-on snow blower with only two powered wheels and two free wheeling casters which provides for the ability to blow snow from narrow paths, turn around without leaving the sidewalk, automatically turn off the auger and present a shovel for performing quick detailed shoveling tasks when stepping off the snow blower.
