Abstract
A microprocessor based, underspeed draft control has been developed and introduced for use on belted agricultural tractors. This system does not rely on costly, strain sensitive pins for operation. By utilizing engine acceleration and deceleration rates, this system is able to respond quickly to needed changes in implement depth, while remaining stable under all operating conditions. The development process relied heavily on real-time computer simulation, minimizing the amount of actual field operation and substantially reducing the development time and expense.
