Mandals Dragman has been designed for the latest environmentally friendly umbilical drag systems. These are used for distribution of slurry and manure as fertilizer in the fields of agriculture.
These systems require hoses to be connected between slurry reservoirs (lagoons) and tow tractors in the field to be fertilized.The tow tractor pulls the draghose behind it while the hose feeds the injection tool bar that deposits the manure in the plowed furrows.The distance between the lagoon and the edge of the field is made up of transfer hoses (Mandals Flexitex / Mandals Superman HVT), but the last one or two lengths before the tow tractor are dragged in the field and put under continuous severe tress.The hose has been 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. Mandals Dragman represents the latest in environmentally friendly and safe manure distribution.
Standard lengths up to 200 meters. For diameter lower than 6 inches, longer lengths on request.
Never tow one part of the hose across another!

To obtain maximum lifetime for the hose, it is recommended that actual Working Pressure and Working Tensile Stress do not exceed 1/3 of the above listed values.
