ABSTRACT:
A hose-drum irrigation machine having a tensioning device engaging the hose at a position adjacent the hose-guide by which the hose is pulled from the drum as the hose is being unwound or by which a drag is applied to the hose as it is being re-wound on the drum, thereby to prevent the convolutions of hose on the drum from becoming loose. The tensioning device comprises an endless belt of which one run extends lengthwise of the hose adjacent the hose-guide and frictionally engages the hose thereby to pull it from the drum where the hose is being unwound or to exert drag when the hose is being re-wound. The belt is driven in the appropriate direction by a driving sprocket driven by a motor.
