Abstract: A mower assembly comprising a grass-catcher bag having an inlet connector for mounting its inlet to the outlet of the mower's grass-discharge outlet, and having a bag-mouth closure at its opposite end mounted on the mower handle. The inlet connector is of a type which slides vertically in and out of its mounted positions, and the rear support for the bag-mouth closure includes an upwardly facing channel, in which lateral ears of the closure rest. A front handle is provided on the bag-inlet connector and a rear handle on the bag-mouth closure, whereby the bag can be removed and replaced easily by simultaneous vertical motion of the two handles.

Abstract: An adjustable V-belt pulley which may be selectively changed form one predetermined effective diameter to another without tools. The pulley comprises first and second separable pulley halves having juxtaposed frusto-conical faces adapted to receive a V-belt pulley therebetween. A plurality of spaced lugs extend axially from the first pulley half and a plurality of sets of cavities are provided in the second pulley half, each set being adapted to receive the lugs of the first pulley half. Each cavity set has a different cavity depth so that the effective pulley diameter is established by the choice of the cavity set into which the lugs are inserted. The pulley halves are concentrically disposed on a shaft and are held together by a wing nut or knurled nut on the threaded shaft end which clamps the pulley halves against a shoulder of the shaft.
