AutoLevel makes GPS-based land leveling easy
AutoLevel is a very precise automatic control system for land leveling equipment. The system uses signals from the global positioning satellites to automatically raise or lower the land-leveling scraper as it is pulled through a field with a tractor. AutoLevel is controlled by a touch screen in the tractor cab and does not require a highly skilled tractor driver. The accuracy of the system is actually better than existing land-leveling systems since it takes into account the curvature of the earth. It is not affected by fog or dust, thus allowing 24 hour a day operation and leveling accuracy is constant throughout the entire working day. It utilizes a portable base station with a range of up to 9.7 kilometers (6 miles) which allows large fields to be leveled without moving the base station. It can be used with either wheel or track type tractors.
