Abstract
A discharge chute assembly for a turf mower having a resilient deflector and a frame connecting the deflector to a mower deck proximate to a side discharge outlet. The frame includes one or more extension elements which engage the deflector. In one embodiment the extension elements are captured within pockets defined within the deflector. The pivoting frame mass facilitates a quick recovery to a guarded condition after the deflector rises in contact with an obstruction. Additionally, the frame mass allows the deflector to maintain an upright, unguarded orientation without additional biasing forces which is useful, for example, during a machine loading operation.
Claims13
A turf mower discharge chute assembly comprising:
- a resilient deflector having a top wall and a cavity extending substantially parallel to said top wall, and having a mount surface angled away from said cavity, with a plurality of apertures extending through said mount surface, and
- a support frame secured at one end of said deflector, said frame aligning said deflector with a side discharge opening of a turf mower, said frame adapted to pivot said deflector about a pivot axis, and said frame defining at least one extension which is inserted into said cavity of said deflector, wherein said frame includes a mount surface adapted to engage said mount surface on said deflector, with said mount surfaces being secured together via a plurality of fasteners passing through the frame and the plurality of apertures of the deflector and being aligned generally perpendicular to said pivot axis, and with said frame defining a pair of frame arms extending in a direction generally opposite said at least one extension, with said pivot axis passing through said pair of frame arms.
A turf mower discharge chute assembly comprising:
- a resilient deflector defining a top wall and a mount surface angled away from said top wall, and a support frame secured at one end of said deflector, said frame aligning said deflector with a side discharge opening of a turf mower, and said frame defining at least one extension which is retained within a closed pocket of said deflector, with said closed pocket being defined between said top wall and a bottom wall of said deflector,
- and with said at least one extension engaging interior surfaces of said pocket, and said frame including a mount surface positioned between said at least one extension and a pair of frame arms, with a pivot axis of the frame passing through the pair of frame arms and with the mount surfaces of the deflector and frame being positioned away from the pivot axis, and with a fastener passing through the mount surfaces of both the deflector and the support frame to secure the deflector to the support frame, and with said fastener being generally perpendicular to the pivot axis of the frame.
A discharge chute assembly for a turf mower comprising:
- a resilient deflector having a top wall and a cavity and a mount surface angled away from said cavity, with a plurality of apertures extending through said mount surface;
- and
- a support frame having at a plurality of extensions and a mount surface angled away from said plurality of extensions and a pair of frame arms extending in a direction generally opposite said plurality of extensions and with a pivot axis passing through said pair of frame arms, said frame being pivotally connected to a mower deck about said pivot axis, wherein said plurality of extensions are received into said cavity of said deflector and a plurality of fasteners passing through the frame and the plurality of apertures of the deflector and being aligned generally perpendicular to said pivot axis.
A discharge chute assembly for a turf mower comprising:
- a resilient deflector;
- and
- a support frame having at least one extension, a mount surface having a plurality of apertures therethrough, and a pair of frame arms, said frame being pivotally connected to a mower deck carrying a rotating mower blade and having a side discharge opening through which said rotating mower blade transports grass clippings out of said mower deck, wherein said at least one extension is received into a portion of said deflector,
- and wherein said portion of said deflector includes a pocket, and with said at least one extension engaging interior surfaces of said pocket, and wherein a pivot axis extends through the pair of frame arms and a plurality of fasteners connecting the mount surface of the support frame to the deflector are generally perpendicular to the pivot axis.
