A trailer dolly comprising a horizontal base plate, a first pair of casters which are fixed from rotation about a vertical axis, a second pair of casters being rotatable around a vertical axis, and a trailer ball. The trailer dolly facilitates the loading of a trailer onto a tilt bed tow truck, including: a disabled trailer, such as a trailer with a broken or damaged axle, frozen wheel bearings, or collision damage to a wheel, axle or components thereof and a trailer which is not fitted with a trailer jack having an attached dolly wheel. The trailer hitch ball of the trailer dolly is connected to a receiver of the trailer tongue, providing support, stability, and steerability, and allowing the trailer to be winched onto a tilt bed tow truck without damage to the trailer tongue, a trailer jack, and/or associated mechanism and wiring.
