1. A method of transporting a mobile aggregate plant comprising the steps of:
providing a first towing tractor attached to an end of a rock crusher section when said rock crusher section is coupled to a material feed section;
charging a feeder air supply reservoir and a crusher section air supply reservoir from an air source on the first towing tractor;
disconnecting an air supply line; a common airbag supply line and an electrical line between the material feed section and the rock crusher section;
turning a rear axle brake valve to an “on” position;
towing the rock crusher section forward, so as to cause a sliding out from under the material feed section, and terminating further relative translational motion;
starting a material feeder section pump and unfold a material feeder trailer jack to a position;
extending the material feeder trailer jack to lift the material feed section;
disconnecting a brake air control line;
towing the rock crusher section away from the material feed section;
backing a second tow tractor under the material feed section;
using the material feeder trailer jack to adjust a height characteristic of the material feed section to allow for an engagement between the second tow tractor and the material feed section;
continuing backing the second tow tractor into the material feed section until a lock engages;
retracting and folding the material feeder trailer jack and turning off the material feeder section pump;
attaching the air supply line to the second tow tractor; and
turning the rear axle brake valve to an “off” position.
