Abstract
Bagging apparatus for a rotary mower in which a grass-catching bag and discharge chute may be detached from the mower in a one-handed operation by the user. A portion of the apparatus connecting the mower housing with the chute and bag also functions as a discharge deflector when the mower is used with the bag removed. The downward deflector is spring-biased toward the downward position and slidably engages a chute to which the grass-catching bag may be attached. Also disclosed is a hook-shaped locking slot on the top of the mower housing into which a projection on the chute may be urged by the spring-biased deflector to positively fasten the chute and mower housing during operation in a bagging mode.
Claims13
Bagging apparatus for a rotary mower having a housing substantially enclosing a blade mounted for rotation about a vertical axis, said housing having a discharge opening for discharge of grass particles cut by said blade from the interior of said housing, comprising:
- a. deflector means hingedly attached to said housing and having a longitudinal axis, said deflector means defining a discharge passageway along said longitudinal axis and pivotable about a generally horizontal axis so that pivotal movement of the deflector means covers and uncovers said discharge opening;
- b. yieldable means for urging said deflector downward toward the top surface of said housing;
- c. a tubular chute member including a top wall and adjoining side walls which define a longitudinal passageway having an axis that is aligned with the longitudinal axis of said deflector means when said tubular chute and said deflector means are attached to each other, one end of said chute member being adapted to mate with said discharge opening, the opposite end of said chute member being adapted to receive a grass-catching bag;
- and
- d. elongated mating channel and projection means, one each carried by said chute and said deflector, said elongated mating channel and projection means each having a longitudinal axis parallel to the aligned axes of said deflector means and said discharge passageway, whereby an operator may attach said chute member to said mower by the axial insertion of said chute member in said deflector means with said elongated channel and projection means cooperating in attachment to permit rotation of said deflector means upward by movement of the inserted chute member downward into contact with said housing.
In combination with a rotary mower having a housing defining a substantial cylindrical chamber in which a blade is mounted for rotation about a substantially vertical axis, said housing having a discharge opening therein, discharge and bagging apparatus comprising:
- a. a discharge deflector hingedly fastened to said housing above said discharge opening in a position to be rotatable downward to shield said opening, said deflector including a top wall to which a pair of opposed side walls are attached to define a discharge passageway extending longitudinally outward from said opening;
- b. a discharge chute defining a transport passageway therein for transport of air and grass clippings to a collecting receptacle, one end of said discharge chute being longitudinally insertable into the discharge passageway defined by said deflector;
- said chute and said deflector including means providing mating engagement therebetween upon such insertion so that said deflector and chute are rotatable as a unit following said engagement;
- c. spring means associated with said deflector and operable to continually urge said deflector toward a downward position shielding said opening, so that said deflector may shield said opening when said chute is not inserted therein, and said chute may be urged into engagement with said housing by said spring means when said chute is inserted into mating engagement with said deflector;
- and
- d. latch means on said housing in the path of downward rotation of the body of said chute when in mating engagement with said deflector, said latch means engageable with said chute for preventing withdrawal of said chute from engagement with said deflector, said spring means urging said chute into engagement with said latch means when said chute is inserted within said deflector into mating engagement therewith.
