Clever extension boosts capacity

Mixer wagon specialist BvL, Germany, has launched the Vario Volume, a clever variable-volume extension as an option for most of its trailed models.

It uses a plastic curtain that can be raised 30cm hydraulically, from the operator’s seat, to effectively increase a twin-auger machine’s capacity by up to 3.5 cu.m.

It’s particularly useful for mixing high dry-matter or fibrous materials like hay or straw bales that can be prone to spilling out over the sides of a mixer wagon when they are first added. 

Once feed is mixed and chopped to the required consistency and the volume is reduced, the extension can be lowered to reduce the machine’s overall height -- useful for feeding inside or under structures with limited headroom. 

BvL (Bernard van Maschinenfabrik) has been in the business nearly 160 years. It started with root cutters and ploughs but now specialises in mixer wagons. The first was made in 1978.
