The RYOBI 40-Volt 20 in. Mower Side Discharge Accessory can be installed in seconds. Using the same innovative design as the easy-lift single-motion lock and release bagger, you can easily attach this accessory by placing it into the bagger connection points and simply lifting it out to remove it. The side discharge accessory efficiently spreads clippings off to the side of the mower without clogging the mower deck. The transition between mulching, bagging and using the side discharge chute requires no tools, simplifying the process even further. This Side Discharge Accessory is compatible with the RYOBI 40-Volt 20 in. Mowers (RY401110, RY401120, and RY40LM30)
