Abstract
A powertrain system for a machine includes a hydraulic variator assembly coupled with a mechanical transmission, and a speed balancing system including a hydraulic accumulator, and being configured to limit a speed balancing error between first and second variators in the variator assembly by commanding adjustment of a valve mechanism to fluidly connect a hydraulic accumulator with one of the variators to increase a fluid flow rate therethrough. The hydraulic accumulator can be charged by way of an implement system in a machine driven by way of the powertrain system.
