Abstract: A bagger with a pair of doors at its opening is provided for a walk-behind lawn mower. The bagger opening is provided with a rectangular metal framework with one door being swingably attached to each spaced-apart vertical leg of the framework. The bagger includes a rear handle for supporting its rear portion from the mower push handle and a front handle integrally formed as part of the framework. The front handle is slidably and removably receivable on a hook secured to the mower discharge chute for quick and easy installation and removal. The dual doors, which swing away from one another, facilitate easy insertion of the bagger opening and doors into or out of a refuse can or bag to permit disposal of clippings.
