Do they have more plans to that?
Produce complete tractors based on ZTS eg or only spare parts?

Ah sorry - my fault in reading...

Interesting: They list 6t capacity for the ZM90 rear axle and 9t for the 120 and 130

Are these a later development that Ursus never had ? A local contractor had two 160hp Ursus for slurry application, but when he broke 7 halfshafts and axle housings in a season (the spare parts were of worse quality than the original) he called it quits and bought some 7200 series Magnums..

The Ursus had the same power as the 7230 but its rear axle just wasnt up to the task... wheel flanges broke, the shaft sheared at the splines in the planet carrier, the trumpet housing cracked, or the pinion shaft bearing broke out of the differential housing..

My mate had a 140hp Ursus, they worked with a 10 ton Taarup 1030 selfloading wagon and a 7500 liter tank, nothing serious, but they also once broke the pinion shaft free in the axle housing.

So, did Ursus ever use the ZM120 or ZM130 axles ?

I see in 1988 the 16245 still used an Ursus rear axle

In 1995 a ZM120 axle is listed

Ursus 1934 z numerem 00001. Jak się pracuje najmocniejszym Ursusem serii ciężkiej? - Maszyny rolnicze

W zeszłym tygodniu informowaliśmy, iż na sprzedaż trafił Ursus 1934 o numerze 00001. Takiej okazji nie mogliśmy przegapić i pojechaliśmy zobaczyć sprzęt na żywo. Unikatowość polskiego ciągnika to jedno, ale dla nas interesujące były także wrażenia z pracy tym 190-konnym Ursusem. Czy to w ogóle...

Ursus 1674 with Perkins engine have Ursus selfmade gearbox and rear axle with parts from KORURS and Lisie Kąty Foundry, Graziano synchrons.

ZTS used poor quality synchros. Often within 3000hrs the synchros of 2nd gear were gone, unless it had a very careful operator.

I did not hear that about the Ursus transmission, apparently they used better synchros...

But anyways, did Ursus ever upgrade the rear axle ?
The 1674 in your video looks like the same diameter ring gear as my mates C-385, not like the picture in your upper post from SEMT where the final drive ring gear is larger than the axle housing in which the brakes sit.....

If Ursus and ZTS joint forces by using a ZTS ZM120 rear axle, and the Ursus synchromesh transmission, both would have had a better tractor...
