info on ZTS super

Anybody have any info on the ZTS super series of tractors? i was passing by ZTS sabinov a.s. the other day and saw a transmission sitting on a truck bed in the parking lot. stopped and took a closer look and it was built very heavily! looked like it belonged in a tank. was similar to the crystal tranny but seemed even more beafy. asked the guy there and he said that it belonged to a ZTS 16245 "super" series tractor that used to be built in Martin slovakia. apparently they were a great machine provided you stayed away from the 40km/h version? would like to get more info on this model if anybody has any. have seen only a few go for sale round here that look tempting.
