The unique Bergmann design holds no magic ingredient. Attention to details and many design features combine to give an accurate, wide, controlled spreading pattern.
Finley uniformly chopped material is evenly distributed across the wide spread width rather than having to rely on larger lumps going further than smaller pieces.
The universal nature of the spreader ensures it can cope with a wide range of materials from heavy long straw cattle muck, through composts, Chicken manures, Ag lime, recycled materials and all between.
Manures have accurately been spread at widths in excess of 30m and as such a Bergmann spreader can adapt to most tramline widths.
