  • Flow control baffle for turf mower
    Patent number: 7866135
    Abstract: A flow control baffle for a turf mower having a plurality of mower blades carried within a mower deck.

The foot wall may be curved and may be movable to define a volute section of variable width. In one embodiment, the flow control baffle includes a panel wall and a foot wall, which are connected together and movable relative to other portions of the mower deck. In one embodiment, the flow control baffle is movable and selectively positioned within the cutting deck in order to optimize mower performance in view of location operating conditions.
