Digging further I found this:
Tytan imports Chinese-built tractors for the North American market and is involved in the design and assembly of their models. Tytan does not confirm the source of its machinery, stating that the production factories are confidential and that several companies are used. Information from several sources, however, indicates that Tytan has a relationship with the Shandong Weitou Tractor (SWT) factory and probably uses Weitou for the majority of their tractor line. Tytan was founded by Mark Leonard, who originally founded the Rhino brand, and was an early pioneer in the sale of Chinese tractors in North America.
and this about SWT factory in China:
