AMAZONE Cirrus drills receive new coulters

AMAZONE’s 6m Cirrus 6003-2 and 6003-2C seed drills are now available with high performance TwinTeC+ double disc coulters that the company said provide accuracy and consistency under all soil types and operating conditions.

“They cut perfect seed furrows with accurate depth at operating speeds of between 10 and 20 km/h,” said CLAAS Harvest Centre Product Manager for AMAZONE, Joshua Patrick.

The 380mm diameter coulters are made of pre-tensioned boron steel for high wear resistance and are fitted on a row spacing of 12.5cm and 16.6cm.

Coulter pressure can be hydraulically adjusted from 15 to 100kg to ensure accurate contour tracking on hilly terrain and precise seed placement, even with small seeds, AMAZONE said.

“This means coulter pressure can be quickly and easily matched to changing soil conditions to maintain consistent depth guidance,” Patrick explained.

“Even with crusted surfaces, heavy soils or undulating ground, the coulter reliably reaches the placement depth.

“The wide spacing between coulters and rows, together with the relatively flat 10-degree pitch of the seeding discs, ensures very good throughput and blockage-free operation, even under different conditions.”

Coulter pressure can be adjusted using the pressure relief valve, while working depth is adjusted using the mechanical crank handles.

Depth guidance rollers with running widths of 50, 65 or 80mm can be fitted to match to light, medium or heavy soil conditions.

A coulter harrow with adjustable operating intensity can be fitted to the wheel carriers of the second coulter row.

Alternatively, the Cirrus can be equipped with the existing RoTeC single disc coulters, which AMAZONE said are ideal for use on heavy or sticky soils or if there is a high amount of crop residues.
