1. A lift device comprising:
a chassis;
a battery coupled to the chassis;
a lift assembly coupled to the chassis and configured to selectively raise and lower a load relative to the chassis;
a front axle assembly pivotally coupled to the lift assembly and configured to rotate about a longitudinal axis relative to the chassis and a rear axle assembly pivotally coupled to the lift assembly and configured to rotate about the longitudinal axis relative to the chassis; and
a controller configured to control operation of a front electric linear actuator and a rear electric linear actuator according to a first mode of operation and a second mode of operation;
wherein in the first mode of operation, the controller is configured to control the front electric linear actuator and the rear electric linear actuator to permit rotation of the front axle assembly and the rear axle assembly relative to the chassis through a first range of motion, and wherein in the second mode of operation, the controller is configured to control the front electric linear actuator and the rear electric linear actuator to limit rotation of the front axle assembly and the rear axle assembly relative to the chassis to a second range of motion.
