Abstract: A suspender for a brushcutter includes a hook member to be hooked on a retaining part and a stopper member to be inserted into the retaining part to keep the hook member hooked upon the retaining part. When the stopper member is pushed down, an elastic piece attached to the hook member is pressed and elastically deforms and opens a hook part of the hook member.

Abstract: An operation-control lever unit for regulating engine power of an engine-powered working machine to control operation of a working tool includes a throttle-lever holding mechanism operative in response to pivotal movement of a lock lever in a locking direction to frictionally hold the throttle lever at a desired position. The throttle-lever holding mechanism includes a stationary cam formed integrally with the head portion of the operator's control handle for the machine, a movable cam on the lock lever and cooperating with the stationary cam to displace the lock lever along a support shaft in a direction away from the stationary cam, and a resilient member disposed behind the movable cam and resiliently urging the movable cam toward the stationary cam.

Abstract: A knapsack type working machine has a first frame and a second frame. A prime mover for driving a working instrument is carried on the first frame. The second frame has a back pad and shoulder straps. The first frame and the second frame are separable from each other. The first frame has a locking engagement member. The second frame engages with the locking engagement member and has a pivotal locking member urged by a spring in a direction of engagement with the locking engagement member. By releasing the locking engagement member from engagement with the pivotal locking member, the first frame is separated from the second frame.

Abstract: A riding-type lawn mower has a cutter housing with a rear discharge slot defined in a rear wall thereof. The cutter housing accommodates a pair of cutter blades laterally spaced from each other and rotatable in a substantially horizontal plane. The cutter blades are arranged such that the cutter blade on the righthand side as viewed in a forward direction of the lawn mower body is rotatable clockwise as viewed in plan and the cutter blade on the lefthand side as viewed in the forward direction of the lawn mower body is rotatable counterclockwise as viewed in plan. The cutter housing has an upper wall that has a pair of laterally spaced portions raised upwardly and defining respective discharge passages in the cutter housing that lead to the rear discharge slot. Rotative power from a lawn mower engine is transmitted to the cutter blades by a belt-and-pulley mechanism disposed on a low flat portion defined between the raised portions of upper wall.

Abstract: A riding lawn mower comprises a frame supported by wheels, a mower housing carried at the underside of the frame, a plurality of cutter blades located within the mower housing to cut grass, a collection bag mounted on the rear of the frame, a discharge chute extending between the mower housing and the collection bag and defining a clipping path from the cutter blades into the collection bag, a blower including an impeller housing attached to the mower housing and an impeller located within the impeller housing and cooperating with the butter blades to convey the grass clippings into the collection bag through the discharge chute. A short conduit connects the impeller housing to the upstream end of the discharge chute to conduct an air generated by the impeller into the discharge chute. A central axis of the conduit is offset downwardly from a central axis of the discharge chute.
