ABSTRACT:
Ground and/or turf penetrating discs for selective attachment to wheels of a lawn mower to increase safe operation of such lawn mowers on embankments. The ground engaging discs, are for selective secured engagement over the hub and tread of one or more of the lawn mower's wheels and include a plurality of outwardly extending projections which penetrate through the underlying grass, if any, and into the sod or earth's surface sufficiently during operation of the lawn mower to prevent its lateral slippage as it traverses a sloped surface. The projections extend completely around the disc and, when used, at least two are extending into the sod or ground or both at all times. The disc has notches for three adjustable holding brackets spaced about equal degrees (120.degree.) around the disc for different size tires. The brackets are removable and secured firmly to the sides and tread of the tires by lock washers and knurled faces. Once adjusted for a tire size, only one bracket need be loosened to install or remove a device from a tire.
