A lawnmower with a mulch plug with a plurality ramps for deflecting lawn clippings out of a cutting deck with more than one depth planes. The mulch plug is configured to attach to the lawnmower by one or more attachment points to block a collector opening of the lawnmower. The plurality of ramps comprises a first ramp and a second ramp on the lower plane of the cutting deck extending downward from the mulch plug. The second ramp is positioned further in the cutting rotation of the lawnmower on a trailing edge of the mulch plug. The secure attachment of the mulch plug with a plurality of ramps provides a more even distribution of grass clippings.
