Amazone says its new six-metre Cirrus 6003-2 and 6003-2C seed drills feature some technical innovations.

Claas Harvest Centre product manager for Amazone Joshua Patrick says the drills are available with TwinTeC+ double disc coulters for rapid sowing of large areas.

"TwinTeC+ coulters provide reliable operation under all soil types and operating conditions," he said.

"They cut perfect seed furrows with accurate depth at operating speeds of between 10 and 20 kilometres an hour."

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

"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," Mr Patrick said.

"This means coulter pressure can be quickly and easily matched to changing soil conditions to maintain consistent depth guidance.

"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 are ideal for use on heavy or sticky soils or if there is a high amount of crop residues," Mr Patrick said.

"The coulter arm, manufactured from forged steel, thickens at the end and is interlocked with tongue and groove, thereby creating a longer and stronger welding seam.

"The coulters are attached to the machine frame via a special bearing clamp made of high-strength forged steel."

Mr Patrick said the coulters incorporated numerous time-saving design features that minimise wear and make maintenance easy.

"For example, the mounting bolts for the disc carrier arms are not threaded into the body.

"Instead, they are mounted using bolts whose nuts are seated within the frame.

"In the unlikely event that an overload causes one of the bolts to break, you can simply knock the nut out with a mandrel.

"Likewise, the PVC seed supply lines can be easily replaced by loosening a single bolt."
