Patent number: 6198986Abstract: A pre-charged multi-variable rate crop input applicator implement comprising a plurality of crop input storage reservoirs located on the implement. The reservoirs on the implement are charged with crop inputs from a remote source. The crop inputs are released from the reservoirs on the implement to the field. Since the reservoirs are pre-charged with crop inputs, the time it takes for a crop input to reach the ground is negligible, making the implement particularly suited to precision farming applications. An accompanying control system controls the rate of discharge of crop inputs at each dispensing point on the implement allowing multiple crop inputs to be applied at a variable rate and at the desired prescriptive mix.Type: GrantFiled: April 30, 1999Date of Patent: March 6, 2001Assignee: Ag-Chem Equipment Co., Inc.Inventor: Alvin E.
