Abstract
An agricultural metering system includes a meter roller having multiple flutes and recesses, in which the meter roller is configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The agricultural metering system also includes a shaft configured to drive the meter roller to rotate, and a clutch assembly operatively coupled to the meter roller. The clutch assembly includes a magnetorheological (MR) fluid, a rotation rate of the meter roller is at least partially dependent on an effective viscosity of the MR fluid, and the effective viscosity of the MR fluid is controllable based at least in part on an effective magnitude of a magnetic field applied to the MR fluid.
