  • ELECTRONIC DRAFT CONTROL FOR TRAILED IMPLEMENTS
    Publication number: 20080257569
    Abstract: A draft load control system for an agricultural tractor towing a trailed, ground-engaging implement that monitors implement height using sensors located on the tractor or sensors coupled to an on-board control communications system and adjusts the implement position in relation to the ground based on draft load, implement height, and tractor wheel-slip to maintain a more accurate, consistent draft load on the tractor while maintaining the implement engaged with the ground and preventing the tractor-implement ground speed from being reduced to zero.
    Type: Application
    Filed: April 17, 2007
    Publication date: October 23, 2008
    Inventors: Chris Foster, Johnny Keplinger, Kevin M. Smith, John Posselius
  • ELECTRONIC DRAFT CONTROL FOR SEMI-TRAILED IMPLEMENTS
    Publication number: 20080257570
    Abstract: A draft load control system for an agricultural tractor coupled to a semi-trailed, ground-engaging implement that monitors implement height using sensors located on the tractor or sensors coupled to an on-board control communications system and adjusts the implement position in relation to the ground through coordinated action of the three-point hitch and the on-implement position actuator based on draft load, implement height, and tractor wheel-slip to maintain a more accurate, consistent draft load on the tractor while maintaining the implement engaged with the ground and preventing the tractor-implement ground speed from being reduced to zero.
