Abstract
A quick attach rotary mower blade system includes a blade holder secured to a mower spindle with a shoulder bolt, a pair of upwardly extending protrusions on the blade holder, and a spring biased plunger extending downwardly from the blade holder. A rotary mower blade has a center hole that slides over the shoulder bolt, compresses the spring biased plunger, and rotates over the protrusions to an engaged position.
