A main tail lock for a hydraulic tail trailer comprising a pair of spaced-apart locks which are pivotally secured to the frame of the tail and which are pivoted between locked and unlocked positions by a lock cylinder. When the locks are in their unlocked position, the tail cylinders for the tail may raise or lower the tail of the trailer. When the locks are in their locked position, the tail cylinders are prevented from retracting thereby preventing the lowering of the tail with respect to the main frame of the trailer.
