Silo Block Cutter HQ plus

HQ plus

Hydrofox HQ plus - A success story since 1971

In 1971, Strautmann presented the first silo block cutter, thus revolutionising silage pick-up. Today, the silo block cutter is still a proven machine which ensures particularly clean picking-up in the clamp silo. Thanks to an improved knife drive, the Hydrofox HQ plus offers a loading capacity of 1.75 - 2.80 m² and still has an optimum cut Surface.
