A lift device (10) includes a base (12) having a first end (20) and an opposing second end (30), a first arm (111) pivotally coupled to the first end, a second arm (131) pivotally coupled to the first end, a third arm (151) pivotally coupled to the opposing second end, a fourth arm (171) pivotally coupled to the opposing second end, and a leveling assembly. The leveling assembly includes a first actuator (200) extending between the first arm and the first end, a second actuator (220) extending between the second arm and the first end, a third actuator (240) extending between the third arm and the opposing second end, a fourth actuator (260) extending between the fourth arm and the opposing second end, and a controller (410) configured to control the first actuator, the second actuator, the third actuator, and the fourth actuator to reconfigure the leveling assembly between (i) a shipping, transport, or storage mode and (ii) an operational mode.
