A power lift assembly includes a lift stand. An actuating unit is detachably coupled to the lift stand and includes an actuating unit frame, a hydraulic unit carried by the actuating unit frame, a hydraulic piston extendable and retractable with respect to the hydraulic unit and an actuating unit arm positional between first and second positions on the actuating unit frame. The actuating unit arm operably engages the hydraulic unit to extend and retract the hydraulic piston at the first and second positions, respectively, of the actuating unit arm. A lift arm is pivotally carried by the actuating unit frame and releasably engages the lift stand. The hydraulic piston engages the lift arm.
