<p>The agricultural irrigation accessory comprises a drum accommodating connecting hoses. The drum (2) turns in a bracket (3), which in turn slews about an axis (6) perpendicular to that (5) of the drum.

The slewing axis can be formed by a tube (7) fitting inside a guide sleeve (8), and attached to the bracket at the top by a pivot pin (12).</p> |
