A trailer incorporating the features of the subject invention has a wheel assembly near the trailing end and a scissors-type lift mechanism near the leading end, with a fulcrum support intermediate the wheel assembly and lift mechanism. The method of lowering the trailer to the ground includes the steps of lowering the leading end of the trailer to the ground with the lift mechanism causing the trailing end to pivot about the fulcrum support into engagement with the ground, further raising the leading end of the trailer to raise the fulcrum support off the ground, removing the fulcrum support, and finally lowering the leading end of the trailer until the entire trailer is in flat engagement with the ground.
