Abstract
An improved mower blade spindle assembly for a rotary mower is provided with an outer shaft having circumferential slots and an inner shaft rotatable within the outer shaft and having a diametral drive pin extending through the slots, and a braking member axially movably mounted on the outer shaft for rotation therewith, the braking member having a braking surface disposed for engagement with an interior surface of a support sleeve in which the outer shaft is mounted and a cammed surface disposed for engagement with the pin such that upon cessation of the input drive, the pin acts against the cammed surface to shift the brake member axially to engage the braking surfaces.
