Slopes or hills on your property can add depth and beauty. But when it comes to caring for these areas, you have to take special precautions. Deciding the appropriate way to mow depends on the mower type. With a lawn tractor, mow up and down for greatest stability. With a walk-behind mower, go side to side. That way, if you trip and fall, the mower is less likely to tumble on top of you. If the hillside is really steep and scary to mow, then don’t mow at all. Instead, plant a ground cover to keep the hillside green and to prevent erosion.
