Abstract: A combination blower assembly and string trimmer (10) whereby the string trimmer head (52) is easily detachable without the use of any tools. The device includes a blower assembly (12) that further includes an upper (14) and lower (16) housing mated together to form a volute-shaped cavity where an impeller (18) with airfoil-shaped blades reside. The detachable string trimmer head (52) is located under the lower housing (16) of the blower assembly (12) and is easily attached or removed from the blower assembly (12) by a simple push and turn motion. The blower assembly further includes an air inlet (20) and air inlet cover (22). When the air inlet cover (22) is rotated to a position where the air inlet (20) is open the blower assembly (12) is operable and the string trimmer (52) is inoperable. Furthermore, when the air inlet cover (22) is rotated to a position where the air inlet (20) is closed the blower assembly (12) is inoperable and the string trimmer (52) is operable.

Abstract: A method of manufacturing injection-molded components having complex features is disclosed. Prior methods typically require the use of a three-piece mold system to form an injection molded component having a complex feature, such as a lawn mower hood having a parabolic shaped front. With the development of a new rigid type of reflective material the present method can thereby utilize a two-piece mold system to form an injection molded component having complex features such as a lawn mower hood having a C-shaped open cavity located at the front of the hood.

Abstract: A six wheeled off-road utility vehicle includes a frame upon which is mounted an engine for use in providing locomotive power to drive the vehicle. A steering wheel is also connected to a steering system for use in providing steering for the ground engaging wheels. Turning the steering wheel rotates a steering column rod about a longitudinal axis and rotates a pinion gear. The first and second front ground engaging wheels are connected to a first axle and first and second rear ground engaging wheels are connected to the second axle. A mechanical linkage is operatively connected between the first and second front ground engaging wheels and the first and second rear ground engaging wheels. The mechanical linkage is engaged in a first linkage direction, the first and second front ground engaging wheels pivot in a first steering direction, and the first and second rear ground engaging wheels pivot in a second steering direction. A steering angle A1 of the first and second front ground engaging wheels forms a steering ratio with the steering angle A2 of the first and second rear ground engaging wheels in the range substantially between 1 and 4.

Abstract: A vehicle drive system includes a frame (12), a motor (14) mounted to the frame, a drive sprocket (48) operatively connected to a motor shaft (46), and a wheel assembly. The wheel assembly includes an axle that is rotatable relative to the frame, a follower sprocket (76) fixedly mounted to the axle, a wheel mounted to one end of the axle and a drive chain (26, 28) engaged around the drive sprocket (48) and follower sprocket (76). The axle is suspended such that it is selectively movable in a generally vertical arcuate path relative to the frame. The vehicle drive system may also include an idler mechanism that engages the drive chain between the drive sprocket and follower sprocket, in order to maintain tension in the drive chain.

Abstract: A control valve (11) and feedback system has three operating states including a lifting state, a neutral state, and a lowering state. The feedback control system comprises a cylinder (40), a pump (38), a reservoir (42) for holding working fluid, and a control valve. The valve body (12) further comprises an inlet port (16), a return port (18), a first work port (36) and a second work port (20). The control valve is plumbed backwards so that the first work port and the second work port are in fluid communication in the lowering state. The valve also comprises a check valve (30) disposed in the first work port. The first check valve is adapted to achieve the neutral state and being selectively adjustable to achieve said lowering state.
