History and legacy
Development of the ZT series began in 1964. The reviewed catalog compresses the late-1980s and early-1990s transition, so it does not establish one definitive shutdown date for every tractor factory or successor activity. Some acquired operations continued until 2004.

Index power values can include estimates derived from belt or PTO power. They are identified on each model card and are not interchangeable with a measured engine rating. Model years and missing values follow the source index.
