1. A drive system for an agricultural vehicle, the drive system comprising:
a chassis;
a power plant operably coupled with the chassis;
a propulsion pump unit connected to the power plant and configured to generate power through a flow of hydraulic fluid;
a first propulsion motor fluidly coupled with the propulsion pump unit and configured to drive a first tractive force to a first wheel assembly, the first wheel assembly positioned fore of a latitudinal centerline of the chassis;
a second propulsion motor fluidly coupled with the propulsion pump unit and configured to drive a second tractive force to a second wheel assembly, the second wheel assembly positioned aft of the latitudinal centerline of the chassis;
a sensor configured to detect data indicative of one or more defined operational conditions; and
a computing system operably coupled with the sensor, the first propulsion motor, and the second propulsion motor, the computing system including a processor and associated memory, the memory storing instructions that, when implemented by the processor, configure the computing system to:
detect the one or more defined operational conditions based on the data from the sensor;
assign the first propulsion motor and the second propulsion motor to a first set or a second set when the one or more defined operational conditions are detected; and
control a flow rate of the first set to operate at a first flow rate and the second set to operate at a second flow rate, the first flow rate less than the second flow rate.
