Abstract
A hydraulic drive system for an agricultural implement includes a high pressure supply line configured to provide hydraulic fluid under pressure. The hydraulic drive system also includes a low pressure return line configured to return the hydraulic fluid. The hydraulic drive system further includes a plurality of hydraulic motors and coupled to the high pressure supply line. The hydraulic drive system still further includes a plurality of cylinder systems isolated from the high pressure supply line to minimize a supply pressure of the hydraulic fluid provided from a pump coupled to the high pressure supply line and to minimize throttling losses in the hydraulic drive system during operation of the hydraulic drive system.
