Abstract: 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.

Abstract: A combination blower assembly and string trimmer whereby the string trimmer head is easily detachable without the use of any tools. The device includes a blower assembly that further includes an upper and lower housing mated together to form a volute-shaped cavity where an impeller with airfoil-shaped blades reside. The detachable string trimmer head is located under the lower housing of the blower assembly and is easily attached or removed from the blower assembly by a simple push and turn motion. The blower assembly further includes an air inlet and air inlet cover. When the air inlet cover is rotated to a position where the air inlet is open the blower assembly is operable and the string trimmer is inoperable. Furthermore, when the air inlet cover is rotated to a position where the air inlet is closed the blower assembly is inoperable and the string trimmer is operable.

Abstract: A mower blade (20) for a lawn maintenance device includes an elongate blade (24) having opposed end edges (26, 28) and opposed side edges (30, 34). The elongate blade (24) is adapted for mounting onto a rotary mower for rotation about a center axis (36) extended transverse to the elongate blade (24) and separating the elongate blade (24) into opposed elongate end portions (38, 40) extended from the center axis (36). The elongate blade (24) has a blade major axis (44) and defines a curved portion (54) such that the curved portion (54) is opposite a sharpened cutting edge (46). The curved portion (54) extends from the elongate blade (24) in an upward direction where the two meet and curves toward a lower face (56) of the elongate blade (24). Further examples of the mower blade (20) include the curved portion (54) being offset vertically from a sharpened cutting edge (46) to develop lift during rotation and a constant cross-section over most of the blade major axis (44).

Abstract translation: 用于草坪维护装置的割草机刀片（20）包括具有相对的端部边缘（26,28）和相对的侧边缘（30,34）的细长刀片（24）。 细长刀片（24）适于安装到旋转式割草机上以围绕横向于细长刀片（24）延伸的中心轴线（36）旋转并且将细长刀片（24）分离成相对的细长端部部分（38,40） 从中心轴线（36）延伸。 细长刀片（24）具有刀片长轴（44）并且限定弯曲部分（54），使得弯曲部分（54）与锋利切割刃（46）相对。 弯曲部分（54）从细长刀片（24）沿向上方向延伸，其中两者相交并向细长刀片（24）的下表面（56）弯曲。 割草机刀片（20）的其它例子包括弯曲部分（54）从锋利的切割边缘（46）竖直地偏移以在旋转过程中产生升力并且在叶片长轴（44）的大部分上产生恒定的横截面。 / p>
