The integrated mechanical seed drills SITERA 3000, SITERA 3500 and SITERA 4000 with a working width from 3.00 to 4.00 m are equipped with the SEEDFLEX seeding unit positioned on 2 offset rows (35 cm apart) and a press wheel as standard. These machines are compatible with the SH 30 small seed hopper. The COMBILINER SITERA is characterised by its exceptional versatility! Performing well when seeding on ploughed land or min-tilled land, the SEEDFLEX coulter bar ensures high quality seeding in all circumstances. The COMBILINER SITERA is precise owing to the HELICA metering unit with volumetric flutes that is not affected by vibrations. It is also simple to use with the centralised depth adjustment and the seed drill ground following is controlled by the power harrow roller.
