Some brands scalp less than others, and as a general rule, a deck that hangs from 3 attachment points versus 4 will scalp less. For example, the new cub decks hang from a rear hanger on each side and a single rod at the front. A certain green manufacture use a similar design at the rear but uses or used, depending on model, they are slowly getting away from this design, a "horse shoe" shaped rod at the front that contacts the deck at 2 points about 6 inches apart. Having 2 points in the front creates a situation where the deck naturally doesn't want to tilt. Think of an atv design, 3 wheeler versus 4 wheeler, and imagine which would pivot better and tilt more to reduce scalping. However with that said, there isn't a way to completely avoid scalping certain areas, other than grab a shovel and flatten the hump. My post above describes how to set up your cutting deck.Is there a way to level the deck so that it won't scalp the lawn????
