Jx Series Placement:
The JX series tractors were developed to offer a robust and versatile utility tractor in the compact to mid-size range, often succeeding models from the older International Harvester or previous Case IH designs.
Manufacturing Origin:
The JX series, including the JX80, were largely manufactured in Europe, particularly in Italy (e.g., former International Harvester plant in Doncaster, UK, or other European facilities before acquisition by CNH Global).
Production Years:
The JX series was produced roughly from the early 2000s through the late 2000s, with specific JX80 production years varying.
