SITERA integrated mechanical seed drill silhouette

The versatile mechanical seeding combination

The SITERA integrated mechanical seed drill has a working width of 3.00m. It is compatible with HR 3020 / 3030 / 3040 power harrows and CD 3020 disc combinations. The SITERA seed drill comes with seeding units with Suffolk coulters, double-disc coulters or SEEDFLEX.

The SITERA seed drill is a very easy-to-handle machine with centralised, continuous adjustment of seeding depth. You can control the machine using an ISOBUS CCI terminal, the tractor’s ISOBUS terminal or the new VT 30 terminal. The new design, perfect visibility, balanced load distribution and forward-set hopper are all elements designed to give you a pleasant-driving experience, both at work and during transport.

Your benefits

Higher precision in any conditions

SEEDFLEX: the precise coulter bar with offset double discs fitted on a parallelogramme on the SITERA 3030 integrated mechanical seed drill.

Offset double discs for perfect furrow opening

The SITERA 3030 integrated mechanical seed drill is equipped with a SEEDFLEX coulter bar with double discs offset by 41mm for perfect furrow opening. The double discs are mounted on a parallelogram with press wheel that controls the depth of each seeding unit with precision. 35 cm spacing between the front and rear rows makes SEEDFLEX seeding units suited to different uses including extreme conditions (heavy and sticky soil) and with no maintenance. Coulter pressure can be set to up to 45kg with the control wheel.

SITERA 3020 for sowing in plant residues

The SITERA 3020 mechanical seed drill is equipped with a double-disc coulter bar fitted over 2 rows, spaced at 25 cm for sowing in difficult conditions. The disc coulter pressure of up to 35 kg ensures regular seeding depth even in irregular soils. The covering harrow fitted on a parallelogram provides a perfect seedbed finish including in soils with plant residues and in heavy or light soils. Press wheels are available as an option for precise control of the seeding depth of each unit.

SITERA 3010 for sowing in all types of clay

The SITERA 3010 seed drill is fitted with seeding units featuring Suffolk coulters that require very little maintenance. Their adjustable lower stop and 35 kg coulter pressure per unit ensure continuously optimum seeding depth, in particular in sticky soil or after ploughing. Take advantage of the 28cm row spacing and the three rows of coulters to seed in all types of clay. The parallelogram makes it possible to adjust the height of the coulter bar by positioning the lower stop at the required depth.

A compact, simple and precise combination

Gain in speed and precision with centralised settings

Take advantage of the centralised, continious seeding-depth adjustment with adjustment point and indicator on both sides of the machine. The patented adjustment system of the SEEDFLEX coulter bar makes it possible to exert the same amount of pressure on the front and rear seeding units.

Benefit from a perfectly integrated combination

The hopper is positioned above the roller frame, so the centre of gravity of the combination is further forward to obtain only slight overhang of the unit. The single-tube chassis provides very good visibility of the seeding units at work and of the covering harrow on the road. The CD seedbed disc cultivator and the power harrow can be fitted or removed in less than 10 minutes thanks to a patented linkage part that facilitates the SITERA seed drill’s coupling and uncoupling.

Easy hopper loading

Easy hopper loading with its large 2.5 m x 0.84 m opening. The cover opens to an angle of 110 ° to allow you to fill the large capacity hopper: 800 L and 1200 L with extension.

Higher precision in all conditions

HELICA metering unit with helical volumetric fluting for the SITERA 3030 integrated mechanical seed drill.

HELICA metering unit with helical volumetric fluting

The HELICA metering unit is capable of distributing seeds of different shapes and sizes: rapeseed, clover, alfalfa, wheat, barley, spelt, fava beans... It ensures seed-by-seed metering to provide uniform distribution in the row. The application rate is constant throughout the operation thanks to the adjustment system by micrometric screw. KUHN’s HELICA metering unit with helical volumetric fluting respects application rates from 1.5 to 450 kg/ha regardless of:
  • changes in seed volume in the hopper,
  • changes in groundspeed,
  • working conditions (uneven land, hilly terrain...).

The easiest calibration control and emptying on the market

The VT30, CCI 800 and CCI 1200 terminals are at your side during your calibration test. Follow the advice of your terminal and you will obtain a perfect setting.
Easy calibration test using one lever to tilt the seeding bar downwards in order to free space for installing the container. Seeds fall directly in the container during the calibration test or the emptying of the remaining seeds. Removing the container is also as simple to remove. The calibration test and emptying can be carried out per half or over the full seed drill width.
Carry out your calibration test easily and sow with your mind at ease.


A wide range of optional equipment is available for the SITERA 3030 range of integrated mechanical seed drills.
