Representative implementations of devices and techniques provide a jointed folding arm assembly. Two or more solid links may be pivotally coupled together to form a jointed folding arm. The jointed arm may be pivotally coupled at one end to a load device. The other end of the jointed arm may be pivotally coupled to a tongue arranged to pull the load device. Further, one or more actuators or cylinders may be coupled to the tongue, the jointed arm, and/or the load device and arranged to fold the load device.
