Abstract
A deflector cup coupled with a mower blade spindle for preventing material from accumulating around the spindle during operation, the deflector cup including a bottom wall having an opening within which the spindle is positioned, and a side wall extending upwardly from a radially outer edge of the bottom wall. A plurality of slots formed in the bottom wall extend radially outwardly from the opening and define finger portions between adjacent slots. The finger portions extend from the opening to the radially outer edge of the bottom wall and are of a size and shape strong enough to prevent the finger portions from deforming when the spindle is positioned within the opening. The finger portions and slots cause the side wall to deform elastically when the spindle is inserted into the opening.

A deflector cup adapted for being positioned on a spindle to which a mower blade is fixed for rotation for cutting vegetation, said deflector cup comprising:
- a bottom wall and a side wall extending upwardly from said bottom wall,
- an opening in the bottom wall within which the spindle is received, said opening being slightly smaller than the spindle such that the spindle fits tightly within the opening,
- at least one slot formed in the bottom wall, said at least one slot extending from the opening to a position proximate the side wall, said at least one slot being adapted to cause the side wall to deflect elastically when the spindle is positioned within the opening for maintaining the tight fit of the opening against the spindle.
A deflector cup adapted for being coupled with a mower blade spindle for preventing materials from accumulating around the spindle during operation, said deflector cup comprising:
- a bottom wall having an opening within which the spindle is positioned,
- a side wall coupled with a radially outer edge of the bottom wall,
- said bottom wall further comprising at least two slots which extend radially outwardly from said opening, and at least one finger portion positioned between two of said slots, said finger portion extends from the opening to the radially outer edge of the bottom wall, said finger portion having a size and shape that is strong enough to prevent the finger portion from deforming when the spindle is positioned within the opening, and said finger portion and slots cause the side wall to deform elastically when the spindle is inserted into the opening.
