Catchers Patents (Class 56/202)
  • Patent number: 4310998
    Abstract: A grass collection cart having an access door and a closed bottom portion receives the airborne grass clippings discharged by a rotary cutting blade assembly. Auxiliary walls on the access door define an air discharge passage having an intake end spaced from the closed bottom portion of the cart and communicating with the interior of the cart when the access door is in its closed position. The discharge passage also has an outlet end opening near the ground. The incoming flow of airborne grass clippings entering the interior of the cart is directed toward the closed bottom portion and away from the intake end of the discharge passage so that the incoming flow of air will be deflected by the closed bottom portion toward the intake end of the discharge passage. The grass clippings consequently settle from the air stream and into the closed bottom portion, and the outgoing flow of air is expelled from the cart through the discharge passage near ground level.

  • Patent number: 4262475
    Abstract: The present invention is directed to an apparatus and method for collecting the discharged grass clippings of a lawn mower. The lawn mower includes a discharge opening at the lateral side or the rear side of the lawn mower. Grass clippings are directed through the discharge opening to a conveyor member, thereafter the clippings are deposited in a catcher. The present invention does not require a high speed air flow to discharge the grass clippings. Further, since the grass clippings are discharged by a conveyor member into the top opening of a catcher the level of grass clippings positioned in the catcher may readily be observed so that it is very easy to determine when the catcher should be emptied.

  • Patent number: 4047368
    Abstract: A riding type mower is provided with a grass catcher attachment having removable container and cover structures. The container structure includes a horizontally disposed quadrilateral frame carrying a large container. The cover structure includes a molded cover and a screen extending downwardly from the cover with resilient clips or latches at the lower edge adapted to snap onto the container frame. A discharge chute from the mower directs the cut material rearwardly to a blower mounted on the rear of the mower. The blower discharge directs the cut grass upwardly toward a deflector formed by the shape of the top of the cover. The user may use the container to catch cut grass or may at his option place three plastic bags, such as garbage can liner bags, in lateral side-by-side relationship inside the container. The plastic bags are held in place by four spring loaded retainers and by the clips which hold the cover structure onto the container frame.

    Abstract: A removable trash bag assembly for lawn mowers, wherein the bag is made of plastic and is hung from a frame attached to the mower. The bag is provided with hanging loops for easy mounting and removal with respect to the frame; and the mounting is arranged to flex the bag in tension to open slits provided in the side of the bag at its mouth due to the increasing weight of the trash as the bag progressively gets filled to exhaust the air when the primary vents in the mid-portion of the plastic are blocked. These slits also function to prevent bursting of a closed filled bag when it is dropped by providing vents at the top of the bag for any entrapped air. These slits are also functional to pass the folded open end portion of the bag therethrough to close the bag.
