An electric lawn tractor power management system and method including a power management switch having a normal mode setting and a power management mode setting. In response to actuation of the power management switch to the power management mode setting, a blade motor controller commands a blade motor to rotate at a power management speed lower than a normal speed, and a traction drive motor controller commands a traction drive motor to rotate up to a maximum power management speed lower than a normal maximum speed. At least one persistence counter notifies the controllers if excess loading conditions exist on the blade motor or traction drive motor. The controllers change the speeds and/or response of the blade motor and traction drive motor in response to the excess loading conditions.
