Abstract
A power machine can include a control device and a hydraulic circuit that can include a hydraulic pump in communication with a hydraulic motor that is configured to operate with infinitely variable displacement. The control device can be configured to determine a control value based on a commanded travel speed for the power machine and a pressure in the hydraulic circuit, and control a run-time displacement of the hydraulic motor based upon the determined control value.
