Abstract
A lawn mower may include a blade housing configured to house at least a first blade and a second blade, a shaft disposed to rotate within the blade housing, a powerhead configured to selectively turn the shaft responsive to application of power from a power source, and a blade coupler configured to selectively couple the first blade and/or the second blade to the shaft to produce different cutting performance conditions based on which of the first blade and/or the second blade is operably coupled to the shaft.
