METHOD OF EVALUATING ACCUMULATORS OF PLANTER DOWNFORCE SYSTEM |
| 摘要 |
A planter downforce system includes a plurality of hydraulic accumulators, each of the plurality of hydraulic accumulators operatively connected to a pressure line associated with a row unit of a planter, a pressure sensor operatively connected to the pressure line, an orifice operatively connected to the pressure line to limit flow of fluid within the pressure line to a hydraulic zero-pressure tank, and a controller operatively connected to the pressure sensor and configured to determine accumulator charge pressure of the accumulators. |

1. A planter downforce system comprising:
a plurality of hydraulic accumulators, each of the plurality of hydraulic accumulators operatively connected to a pressure line associated with a row unit of a planter; a pressure sensor operatively connected to the pressure line; an orifice operatively connected to the pressure line to limit flow of fluid within the pressure line to a hydraulic zero-pressure tank; a controller operatively connected to the pressure sensor and configured to determine accumulator charge for the accumulators. |
