A lift device includes a chassis, a lift boom, a sensor, and a controller. The chassis includes a frame, an axle pivotally coupled to the frame, and an actuator positioned to move the axle. The lift boom is rotatably coupled to the chassis and operable within a work envelope, and the sensor is positioned to monitor an orientation of the lift boom. The controller is configured to engage the actuator based on the orientation of the lift boom. Engagement of the actuator moves the axle to adjust the work envelope of the lift boom.
