摘要： A log splitter (10) includes a pump (24) connected to a hydraulic reservoir (30) and an elongated beam having a splitting wedge and a support plate mounted thereon. A hydraulic ram (22) provides relative motion between the wedge and the plate to split logs. The ram (22) includes a cylinder (50), a piston positioned within the cylinder, and a piston rod (52) reciprocally movable within the cylinder. The hydraulic ram also includes a control valve (62) connecting the pump and the cylinder. The first end collar (54) includes a first cylinder head and a valve body of the valve (62) cast as a single component. The valve body defines an inlet port (70), an outlet port (72), an "A" port and a "B" port. The second end collar (56) includes a second cylinder head and defines a channel fluidically connected to the "B" port. The first and second cylinder heads are sealingly held on ends of the cylinder with tie rods (58).

摘要： An adjustable nozzle for use with a chipper-shredder vacuum for vacuuming debris from an outdoor surface is disclosed. The nozzle has an inlet for directing debris into the nozzle. The inlet has a first side, a middle section, a second side, and a non-inlet area. The first side has a first nozzle inlet, the middle section has a middle nozzle inlet, the second side has a second nozzle inlet. The cross-sectional areas of the first and second nozzle inlets are greater than the cross-sectional area of the middle nozzle inlet to equalize vacuum force throughout the nozzle. The nozzle further includes a nozzle extension that extends below the nozzle and an adjustment apparatus for adjusting the height of the nozzle extension from the ground to conform the chipper-shredder vacuum to the terrain. The nozzle extension may be raised for bumpy or thick terrain or lowered for a flat terrain.

摘要： A clutching mechanism (20) for a cultivating tiller. The tiller has an engine (16) mounted on a frame (12) with a rotatable output shaft (40), a rotatable working shaft (22) , and a transmission (18) operatively connecting to the working shaft, the transmission having a rotatable transmission shaft (42) coaxially aligned with the output shaft of the engine. The clutching mechanism includes an upper half pulley (52) attached to the output shaft, and a lower half pulley (54) attached to the transmisson shaft, wherein the upper half pulley and lower half pulley are coaxially positioned in a facing but non-contacting relationship such that the upper half pulley is able to freely rotate with respect to the lower half pulley. The clutching mechanism also includes a belt (62) positioned between the upper half pulley and the lower half pulley, and a tensioning assembly (70) configured to selectively tension the belt so that the belt transmits rotation of the upper half pulley to the lower half pulley.
