A mulch kit control lever with a detent plate attached to the top surface of a mower deck, and a vertically oriented pivot pin extending through the detent plate and through the mower deck and engaging a mulch gate. A pivoting handle connected to the pivot pin moves the mulch gate between a side discharge position and a mulching position. A detent pin on the handle abuts a first stop on the detent plate in the side discharge position and a second stop on the detent plate in the mulching position.
