Abstract: A blade adapter for attaching a mower blade to a blade drive shaft of a lawn mower is disclosed. The blade adapter includes first and second extensions that extend beneath the bottom surface of the blade adapter and correspond with holes located along a longitudinal axis of the mowing blade equadistance from the center hole of the mowing blade. The first and second extensions act to pass torque between the blade adapter and the mowing blade, thereby reducing stresses on the teeth and slots of the central section of the blade adapter and mowing blade. A method for installing a mowing blade onto the disclosed blade adapter is also disclosed which includes the step of aligning the first and second holes of the mowing blade with the first and second extensions of the blade adapter and aligning the central star hole of the mowing blade with the central star section of the blade adapter.

Abstract: A lawn mower has a grass bag assembly and a chute assembly. The grass bag assembly has a grass bag for holding lawn debris, a grass bag door for releasing stored lawn debris from the grass bag, a support rod connected to the handle bar of the mower, and support pins connected to the body of the mower. The chute assembly has a chute which is used to transport the lawn debris from the body of the mower to the grass bag, and a chute door. As the grass bag is lifted off the apparatus body, it causes the chute door to pivot about the chute. The pivoting chute door moves the extended pull rope of the mower out of the way of the grass bag. The grass bag can then be fully removed from the apparatus body and emptied of its lawn debris. Finally, the chute door is raised so that the empty grass bag can be repositioned onto the apparatus body.
