Abstract:
A rotary cutting deck for a mower, which comprises:(a) at least one cutting chamber formed by a top wall and a peripheral wall having a lower edge; (b) a rotary cutting blade carried in the cutting chamber for rotation in the cutting chamber, the cutting blade rotating about a substantially vertical axis in a substantially horizontal cutting plane when the cutting deck and rotary cutting blade are in operation; (c) a grass discharge outlet in the peripheral wall of the cutting chamber adjacent the lower edge of the peripheral wall for allowing grass clippings to exit from the cutting chamber in a substantially horizontal path; and (d) a ramp located adjacent at least the peripheral wall of the cutting chamber, wherein the ramp has a progressively increasing depth between a front end and a rear end thereof such that the ramp progressively moves away from the top wall and towards the lower edge of the peripheral wall as the ramp extends between the front and rear ends thereof such that grass clippings travelling within the cutting chamber and engaging the front end of the ramp will be progressively forced downwardly by the ramp away from the top wall towards the grass discharge outlet adjacent the lower edge of the peripheral wall, wherein the front end of the ramp is ahead of the grass discharge outlet and rear end of the ramp is located adjacent some portion of the grass discharge outlet.
