With working widths of 9.0m and 12.0m, the Optimer L 9000 and L 12000 disc stubble cultivators are the widest so far from the French company.

Previewed at a European press event near Strasbourg (France), the two newcomers support the existing 4.0m, 5.0m, 6.0m and 7.5m trailed models.

Main features include a ground tracking system, which ensures that each chassis section operates independently for an even working depth across the entire width. Depth adjustment is controlled hydraulically from the front cylinders, and turning on the front wheels and rear rollers helps to reduce headland compaction.

Working at an average speed of 15km/hr, potential outputs of up to 18ha/hr are possible, and the company claims that the 550mm of underbeam clearance is one of the widest on the market.

Equipped with 510mm diameter (6.0mm thick) discs, transport dimensions of both 9.0 and 12.0m models is 3.0m (width) and 4.0m (height). The official launch of the two new models, which on the road can travel at 40km/hr, will take place at Agritechnica in November.
