Spreader tanks from GEA Houle are not just built they are engineered for the ultimate combination of efficiency, strength, and weight. This allows you to haul more manure and minimize down time. Tank reservoirs are constructed with high quality ¼” steel with the upgrade option for 3/16” stainless steel. One layer of Epoxy primer and 1 layer of Urethane paint resists extreme conditions and ensures long operating life.
