Abstract: A chipper vacuum shredder system and apparatus includes a chipper mechanism, a shredder mechanism and a vacuum mechanism carried by a mobile platform. The vacuum mechanism is coupled to a passage having a nozzle. The nozzle includes an adjustable baffle structure for varying the velocity of air flow for delivering yard waste to the chipper-shredder mechanism. The mobile platform includes a bellcrank height adjusting mechanism which varies the height of the nozzle over a surface to be vacuumed, thereby increasing performance on varying surface conditions, particularly when used in conjunction with the adjustable baffle structure. An adjustable deflector is coupled to an exhaust portion of the vacuum mechanism for directing a stream of air to move yard waste and the like as desired. The chipper system is accessed through a cone-shaped inlet through which branches to be chipped can be inserted.

Abstract: The four-wheel lawn and garden tractor has an underslung two blade mower unit and a rear mounted grass catcher. The multiple spindle mower unit incorporates special baffling to improve lateral movement of cut grass from the mower housing. The conduit between the mower housing discharge opening and the rear mounted grass catcher includes a unique elbow part having a configuration which facilitates efficient movement of the grass from the mower to the catcher. The grass catcher is vented so that there is very little back pressure in the interior of the grass catcher. Venting is accomplished by provision of a downwardly facing opening along the rear of the grass catcher cover, the latter being molded of an impervious plastic material. The grass catcher cover has a downwardly extending skirt at the front thereof with a pair of laterally spaced semicircular notches adapted to receive a discharge conduit. Thus the cover may be used on tractor mowers discharging to either their left or right side.
