Abstract
A mower deck comprises an auxiliary source of pressurized air in order to avoid clipping buildup under the mowing deck, most particularly at the trailing edge of the discharge chute. The auxiliary source of air comes through a cloverleaf shaped hole in the mower deck. The spindle is mounted to the mower deck through this hole, as in conventional mowers. However, unlike conventional mowers, because the hole in the mower deck has a cloverleaf configuration air can flow through the corner portions of the cloverleaf configured hole and act as an auxiliary source of air even though the spindle is mounted to the mower deck through the hole.
