This useful equipment consists of a frame with an hydraulic gear motor with lever junction which moves an interchangeable roller to unroll and rewind long strips of double strength net (anti-thorn and anti-tear).
When the lever junction is released and the roller in neutral, you can unroll the first net on the ground on the outer side of the olive trees row; to unroll the second net, the empty roller must be removed and proceed as above.
Once all nets are rolled, two operators widen them up to completely cover the inter-rows.
After the collection is completed, the first net on which the olives fell must be rewinded: moving the tractor in the direction of the net, with the lever junction put in, it’s rewinded on the roll while the olive pile is moved forward. Before complete rewinding, the operator pickes up all olives and then, unrolles the net on the first uncovered row.
