发明名称 Lawn grooming and rolling accessories for lawn mowers
摘要 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. This invention overcomes prior art problems introduced by fully engaged lawn rollers carried by lawn mowers and those spring biased downwardly into the lawn, which facilitate scalping or the temporary bending and creasing of grass stems which thereafter revive to provide a grain and unkempt appearance that is particularly intolerable on golf greens or formal gardens, for example.
