Cooperation

Strojírny Rožmitál is a machinery plant with a long tradition of manufacture, which reaches up to the beginning of the past century. The company was founded in 1913, then metal parts of furniture, air-conditioning equipment and electromotors were produced here.

The manufacture of the agricultural technology in Strojírny Rožmitál began in 1946 and lasted until the present time. At present, haymakers and swatch turners are produced here. The machine works have departments of development, design, technology and the actual toolshed for the production of preparations.

The current production is divided into several areas:

• Production of Agricultural equipment, haymakers up to the maximum reach of 8.9m, rakes up to the max. reach of 13.3 m
• Production of semi-finished products for the final assembly in RAVAK Příbram
• Cooperation for the foreign companies (Germany, Netherlands) – machining, welding
• Cooperation for the local companies – machining, welding
