A drive and control system for a lawn tractor includes a CAN-Bus network, a vehicle controller, a pair of hydrostatic or electric transaxles controlled by respective electronic drive controllers, and one or more steering and drive input devices coupled to respective sensor(s) for sensing user steering and drive inputs. The vehicle controller communicates with one or more vehicle sensors and one or more vehicle controllers that control one or more vehicle components via the CAN-Bus network. The vehicle controller processes the user's steering and drive inputs and posts on the CAN-Bus network digital drive signals configured to obtain the desired speed and direction of motion of the lawn tractor. The electronic drive controllers convert the digital drive signals to appropriate signals for driving the hydrostatic transaxles or the electric transaxles, as equipped, based on tunable motion parameters to obtain the desired speed and direction of motion of the lawn tractor.
