A prototype in-field transport system for high-value crops was designed and built. This system carries a semi-trailer upon two rubber-tracked undercarriages. A mechanism was designed for timely assembly and disassembly of the system. A set of field experiments was conducted to compare the sinkage, motion resistance, and drawbar forces of the rubber-track versus the current pneumatic-tire system. Increased flotation was observed with the prototype system. The motion resistance of the track system was less than or greater than that of the pneumatic-tire system depending on the soil condition. The prototype met performance objectives during assembly, operation, and disassembly of the system.
