We are your system partner for crop flow
PRÄZI GROUP has been producing high-quality components for over forty years in close cooperation with the agricultural machine industry. Many of our partners appreciate our specialising in rotation components for the agricultural machine industry, since our products are durable and robust.
We focus on rotation components for combines, harvesting attachments, self-propelled shredders, beet harvesters, potato harvesters and transfer vehicles .
