A control system for mixing materials for livestock feed including a container (B-1100) that receives the materials, agitators (B.1300) that mix the materials in the container, a driveline (B-1200) that drives the agitators at an output speed with an output torque, a power source (C-1000) that provides an input speed at an input torque, a continuously variable transmission (A-1500) that connects the driveline and the power source and having a hydrostatic loop (A-1520) to provide a speed ratio between the input speed and the output speed, a plurality of sensors (A-1400) positioned between the power source and the agitators that provides mixing signals commensurate to mixing parameters, and an electronic control unit (A-1100) configured to receive the mixing signals, extract mixing parameter values from the mixing signals, and actuate the continuously variable transmission and adjust the speed ratio based on the mixing parameter values to enhance efficiency of the mixing of the materials.
