The export Dexta's were primarily meant for foreign markets and you can actually find them all over the world. The Fordson 2000 is an export model of the Super Dexta meant specifically for the USA. The specifications of the Dexta and New Super Dexta export models were published as part of the Export Operator's Manual, the cover page of which is included below. Note the "export" moniker in the upper right corner.

The New Super Dexta is the third and last generation of Dexta's and is also known as New Performance Super Dexta. It had extra power due to increased engine revolutions (from 2.400 to 3.000 rpm). See Questions and Answers for a complete listing of the various Dexta models that were made.
