Abstract
A system to prevent engine stalls for a machine having a power source is disclosed. The power source is in communication with a controller, which is configured to determine the temperature of the power source and compare the temperature of the power source to a predetermined threshold temperature. The controller is configured to disable power source braking if the temperature of the power source is less than the threshold temperature. The controller is further configured to determine the power source speed and the travel speed of the machine, and disable power source braking if the power source speed and machine travel speed are less than predetermined thresholds.
