Abstract
A lawn mower blade includes a mulching blade and a discharge blade which operate in combination. Both the mulching blade and the discharge blade have primary and secondary cutting surfaces. Optional cut-out regions provided in both blades reduce the total weight of the lawn more blade. A third cutting surface can be provided in both blades by sharpening the trailing edge of the cut-out region. The primary cutting surface of the mulching blade resides on a first horizontal cutting plane, while the primary cutting surface of the discharge blade resides on a second horizontal cutting plane which is elevated above the first horizontal cutting plane of the mulching blade.
