Hydraulic control system and associated methods to control a drum and spindles of a cotton harvester

A non-transitory machine-readable medium comprising instructions that, when executed, cause at least one processor circuit to:

• generate a first control signal for a pump operatively coupled to a first motor, the first motor operatively coupled, via a variable transmission gearbox, to a drum and spindles of a row unit of a cotton harvester, wherein the pump is configured to generate, responsive to the first control signal, a first fluid flow to the first motor, the first motor configured to cause rotation of the spindles based on the first fluid flow;
• and
• generate a second control signal for a valve operatively coupled to a second motor, the second motor operatively coupled to the drum via the variable transmission gearbox, wherein the valve is configured to control, responsive to the second control signal, a second fluid flow to the second motor, the first motor and the second motor configured to cause rotation of the drum based on the first fluid flow and the second fluid flow.
