The main bed of an implement trailer is lowered to the ground by pivoting a rear frame and forward gooseneck toward the main bed. The main bed is raised from the ground by pivoting the rear frame and forward gooseneck away from the main bed. A battery, electric motor, and hydraulic pump mounted on the gooseneck provide hydraulic pressure to operate hydraulic cylinders connecting the rear frame and gooseneck to the main bed. The battery is recharged from a towing vehicle.
