Dragman

Mandals Dragman and Dragman Extra are designed for umbilical drag systems used for distribution of slurry and manure in agricultural fields. Hoses are connected between slurry reservoirs (lagoons) and tow tractors. Between the lagoon and the edge of the field transfer hoses are used (Mandals Flexitex / Mandals Superman HVT), but the one or two lengths behind the tow tractor are dragged in the field and put under continuous severe stress. Mandals Dragman and Dragman Extra are designed with this extreme tensile stress and abrasion in mind. The TPU cover has abrasion resistance 4 – 5 times that of commonly used rubber. The tensile strength has been substansially increased to withstand the pull forces.

Standard lengths up to 200 meters. Longer lengths on request for diameters lower than 6 inches.

NOTE:  Never tow one part of the hose across another!
