Abstract: An improved lawnmower mulching attachment for comminuting grass clippings cut by the mower is provided having a housing defining a mulching chamber, a rotatable mulching impeller within the chamber and a duct intercommunicating the housing and the mower deck, wherein the attachment effectively utilizes the momentum of the laterally discharged grass clippings and suction pressure created by the mulching impeller to transfer the clippings from the mower deck to the mulching chamber. The housing includes an outlet for discharging the comminuted grass clippings and a bottom wall having an inlet leading to the mulching chamber. The housing is mounted above the mower deck of the mower such that the upright axis of the mulching impeller is laterally offset from the upright axis of the cutting element. Further, the duct is connected between the inlet of the housing and the lateral discharge of the mower deck for transferring grass clippings from the deck to the chamber.

Abstract: A lawn mower blade lock is provided which is especially useful for servicing a lawn mower by enabling both lifting one side of a lawn mower to expose the blade and simultaneously securing the blade of the mower against rotation during efforts to remove the blade. The lock includes a handle and a pair of blade constraining barriers which extend beneath the mower deck and resist rotation, combined with a locking mechanism which attaches to the mower deck. The locking mechanism preferably includes a threaded shank which clamps the mower deck between the barriers and an abutment on the shank for resisting rotation of the blade relative to the deck. In this manner, the lock is easy to attach and remove, and thus is also useful during storage of the mower to prevent inadvertent starting of the lawn mower by children. Moreover, the lawn mower blade lock is economical to construct and easy to attach.
