    Abstract: A lawnmower with a mulch plug with a plurality ramps for deflecting lawn clippings out of a cutting deck with more than one depth planes. The mulch plug is configured to attach to the lawnmower by one or more attachment points to block a collector opening of the lawnmower. The plurality of ramps comprises a first ramp and a second ramp on the lower plane of the cutting deck extending downward from the mulch plug. The second ramp is positioned further in the cutting rotation of the lawnmower on a trailing edge of the mulch plug. The secure attachment of the mulch plug with a plurality of ramps provides a more even distribution of grass clippings.

    Abstract: Fastening method, assembly and structure of engine oil fill extension tube can include an oil fill extension tube and a self-locking washer. The oil fill extension tube can include a plurality of locking edges disposed towards a first distal end of the oil fill extension tube, where the plurality of locking edges can define boundaries of a plurality of slots. The self-locking washer can include a plurality of teeth disposed on its top surface. The self-locking washer can be oriented over an opening in the oil pan, after which the oil fill extension tube can be threaded into the opening. The plurality of slots and plurality of teeth can be ratcheted together to fasten the oil fill extension tube into the oil pan when the oil fill extension tube is rotated clockwise. The washer can further include a locking extension to securely engage a portion of the oil pan.

    Abstract: An anti-rotation apparatus usable with power driven equipment. The power driven equipment may include a deck, a deck bracket connected to the deck, and a handle. The handle may be pivotally mounted to the deck bracket and capable of rotating in a first direction and a second direction opposite the first direction. The anti-rotation pin has a first portion configured to prevent rotation of the handle in the first rotational direction; and a second portion configured to prevent rotation of the handle in a second rotational direction opposite the first rotational direction.
