Abstract: A snow thrower including an auger housing, a center snow impelling blade housed within the auger housing, a first blade positioned on a first side of the center snow impelling blade and configured to be driven about a rotational axis of a drive shaft, and a second blade positioned on a second side of the center snow impelling blade and configured to be driven about the rotational axis of the drive shaft. The first blade and the second blade are housed within the auger housing and configured to drive snow to the center snow impelling blade. The auger housing directs snow to the center snow impelling blade, the first blade, and the second blade.

Abstract: A snow thrower may include a housing, a rotatable snow moving member at least partially within the housing and a compressed gas knife coupled to the housing and aimed at an underlying terrain forward the housing.

Abstract: A snow thrower may include an auger housing; and an auger flight assembly. The auger flight assembly may include a drive shaft rotatable about an axis and helical blades and helical pliable flights, wherein the helical blades and the helical pliable flights alternate with one another along an axial length of the drive shaft.

Abstract: A mower-mounted grass catcher and reel lawn mower assembly and method of making same. The catcher has two spaced-apart bores which receive two pins on the mower for mounting the catcher in a cantilever manner and on the mower. The bores are strengthened and are located in the opposite sides of the catcher which also has two handles for maneuvering the catcher. The upper panel and the lower panel of the catcher, adjacent the opening for the clippings, are reinforced with ribbing. The catcher is molded for extra-strength in the area defining the bores.

Abstract: A shear clutch assembly for a rotatably driven power transmitting shaft and including a shear bolt which is sheared and causes a disconnect in the driving parts for the shaft. The assembly includes a flange rigidly fixed to the shaft and a rotatably driven member, for example, such as a sprocket rotatably mounted on the shaft and connected to the flange by the shear bolt. A reversing drive mechanism is carried by the driver or the driven member and when the power is transmitted in the normal or forward direction, the reversible drive connection is ineffective. However, when the shear bolt means has been severed and dislodged, power can be reversed and this causes the reverse drive connection to become effective for driving in the reverse direction.
