A mower for cutting grass includes a platform with a motor located thereon. A door on the platform has a first position blocking a discharge and a second door position away from the discharge. A bag has an inlet that mates to a discharge. A support is connected to the platform and a door prop is movably mounted on the support. The door prop has a first position not in engagement with the door to permit the door to be in the first position and having a second position in which a segment of the door prop engages with the door to retain the door in the second position. A handle extends up from the platform. An operable member is mounted on the handle. A connector extends between the door prop and the operable member to transmit force to move the door prop.
