Abstract: A granular fertilizer spreader which may be attached to a lawn mower (1). The spreader includes a hopper (44) which is secured to the mower handle (3), the spreader including drive wheels (9,10) which frictionally engage the rear mower wheels (7,8). An impeller (99) is rotated by the drive wheels (9,10), thereby urging fertilizer or other granular material contained within hopper (44) to exit through a series of orifices (73-84) located along the bottom surface (54) of the hopper (44). A discharge chute (134) entrains the fertilizer as it exits the orifices (73-84) and guides the fertilizer along a series of open channels (138-149), each channel terminating with an outlet orifice (152-163 ) through which the fertilizer is ultimately deposited upon the ground behind the mower deck (2). The drive wheels (9,10) are urged into positive frictional contact with the mower wheels (7,8) by a spring (187) that is secured to the mower handle (3) at a user selected point by a clamp (196).

Abstract: A snowthrower (20) including an improved impeller (50) which has an "open center" configuration and which is substantially made from a single piece of plastic. Impeller (50) includes a pair of curved blades (60) which are supported, braced and stiffened by a plurality of "spiders" (62, 64, 66, 68, 72, 74, 76 and 78) which form recesses for receiving a shaft (42) which spans between the side walls (36) of the snowthrower housing (22). Curved blades (60) of impeller (50) extend transversely between a pair of somewhat circular plates (52, 54). Plates (52, 54) preferably include teeth (54b, 54c, 52b, 52c) which help to break up snow and ice and assist in propelling snowthrower (20).
