Abstract: This invention provides improved lawn rolling equipment for grooming lawns. To resolve the "Lazarus" effect of recovery of bent over grass stems that make a freshly mowed lawn look unkempt and ragged, a lawn mower accessory is provided with a roller that is manually bistably positioned between a rolling-on-the-lawn-surface working position and a retracted-off-the-lawn-surface idling position so that mowing may be selectively performed with or without the accompanying rolling step. The prior art has not provided simple, inexpensive equipment, such as here provided, that can improve the appearance of lawns even when double mowed by the criss-cross method because there is a higher probability of removing unwanted grain and uneven grass lengths caused by grass stems bent in one direction by the rolling that revive after mowing to introduce graininess and untidiness.

Abstract: A shaft-grounding stuffing box cover (10) includes an annular nut-base (12) that includes a central aperture (14) through which a rotating shaft (16) passes. Two grounding tabs (28 and 30) project longitudinally upwards from the proximal end of the nut-base (12) adjacent the rotating shaft. The grounding tabs include diametrically opposed radial openings (18) that are longitudinally displaced from each other for the mounting of conductive brush contacts (20) therein. The conductive brush contacts are biased against the rotating shaft by backing springs (46), and are retained within the radial openings by hollow bolts (48). The hollow bolts, spring, and brush contacts form an electrically conductive path to the rotating shaft for grounding of the shaft.
