A device for the comminution of leaves for the preparation of fine particles for a mulch useful with a leaf comminuting apparatus having an opening for the escape of comminuted materials, comprises a comminuting grid adapted to be disposed over the opening for further comminuting said leaves, said grid comprising a plurality of vertically suspended chain elements in lateral contact with each other. The grid includes a generally rectangular support plate defining a plurality of slots, and the chain elements are mounted on a support plate with their uppermost links extending through the slots. An elongated rod passes through the uppermost links and is adapted at one end thereof to nest within an opening provided in the support plate. The chain elements provide a simple expedient for the fine comminution of leaf matter which is durable in use. The present device is also self-cleaning, as the contiguous chain elements serve to remove accumulated leaf matter from each other during use.
