The size of the hose is normally 6’ and 8’. The length can be from 1 span to 7 spans, normally not more than 7 spans because of the hose weight limitation 450m length. Hose feed system requires on ground hydrants and underground pipeline.
This system is mainly used for grasses, grains, vegetables, cotton and sugar cane crops. The length can be from 1 span to 18 spans, normally more than 7 spans system is economical. Lateral move system is the only machine which can irrigate all land. In square land, all spans are parallel with the land, no blind angle. The irrigation ratio can increase to 99%.
Water source to fill the machine can be canal, concrete ditch, rivers and pond. It is not allowed to operate the machine without water.
