Abstract:
A vehicle such as a riding lawn mower may have at least one electric drive motor configured to drive at least one wheel, at least one electric blade motor configured to drive at least one cutting blade, and a battery module connected to the drive and blade motors. According to some embodiments, a method of controlling the vehicle may include: operating the blade motor according to a blade target speed; monitoring a blade current load for the blade motor; comparing the blade current load to a light load low threshold for the blade motor; and if the blade current load is less than the light load low threshold, decreasing the blade target speed.
