Abstract: Device for collecting or directly depositing cut grass for a lawnmower, mounted on the rear surface of a mower (2) and applied to the ejection channel (3) of this latter. The device has a removable bottom (4) detachably connected thereto, wherein after removal of the removable bottom (4) the device permits directly depositing the cut grass if collection is not desired. The removable bottom (4) is in the form of a rigid plate provided at one end with hooks (5) adapted to coact with a lower cross member (6) of the collecting apparatus and, at its other end, with a lock (7) for locking in closed position coacting with another lower transverse member (8) parallel to the first.
