Abstract
A walk behind lawn mower has an exit tunnel that is opened and closed by a pivotal mulch door to convert the mower between collecting and mulching modes of operation. An operating handle fixed to the mulch door includes a vertically reciprocal push button for releasing locking tabs that engage detents for holding the mulch door in the open and closed positions thereof. The bottom wall of the exit tunnel has a steeply inclined rear ramp section that is angled upwardly relative to the horizontal at least approximately 45°. The rear discharge opening of the exit tunnel occupies approximately an upper quarter of the area of the rear face of the cutting deck. Grass clippings flow into the upper portion of a grass collector through this high, steeply angled exit tunnel to promote even and full filling of the grass collector in the collecting mode.
