Abstract
A torque balancing scheme for a velocity controlled drive system of a mower is provided. The torque balancing scheme can be employed on any mower or other similar vehicle having a drive system in which a separate motor is used to independently drive each wheel. By implementing the torque balancing scheme, a drive system can prevent excessive heating of the motors that may otherwise occur when unaccounted-for factors exist.
