Abstract
A system for easily installing and removing a knife for a rotary mower system includes a mower disc having a body including an elongated slot. A retention block includes a pocket defining a radially outer portion and a radially inner portion. The retention block includes a cover portion covering the radially outer portion of the pocket and the elongated slot. A pin passes through the elongated slot and is moveable within the elongated slot along a radially extending path between the radially outer portion and the radially inner portion of the pocket. When the pin is disposed in the radially outer portion, the cover portion of the retention block covers the pin to prevent withdrawal of the pin from the elongated slot. When the pin is disposed in the radially inner portion, the pin may be removed from the elongated slot through an access opening.
