Abstract
Abstract This disclosure relates to a transportable vehicle comprising a vehicle body and a trailer frame assembly. The trailer frame assembly includes an extensible draft bar that may be pivoted from a generally horizontal position where it is adapted to be connected to a draft vehicle, to an inclined position folded-up against the vehicle body so that it is out of the way when so desired.
