The Signature name says it all. Vermeer introduced the “One-Man Hay System" in 1971 to help farmers and ranchers get the job done. The 504R Signature baler advances this legacy by giving the working man a baler for any operation. Designed for producers who harvest primarily dry hay but also want the ability to bale silage when the weather isn't on their side. It is built upon the three signature pillars of Vermeer balers — convenience, ease of use and durability.
