Hoelscher graders like this one are available in 6 feet or 8 feet and can be pulled with 25- to 50-horsepowered tractors. A 3-point hitch and one hydraulic circuit are required. The graders run from about $4,000 to $4,500. This unit also has an optional spill guard that can be used to prevent soil from spilling into the grass along a driveway or road, or can be used to convert the grader into a box scraper.
