Abstract
A quick change rotary mower blade system includes a spindle having a vertical axis of rotation extending through a mower deck, and a ring shaped metal spring between the spindle and a retainer. The retainer may be turned less than 90 degrees on the vertical axis of rotation to compress the ring shaped metal spring sufficiently to clamp the mower blade. A plurality of detents hold the retainer in the position where the retainer compresses ring shaped metal spring, and release the retainer by translating the retainer downwardly along the vertical axis of rotation.
