MECA V4

The heavy-duty parallel linkage with a large clearance is mounted on interchangeable bushings.
For better stability of the metering unit, an additional spring with adjustable pressure is available.

The MECA V4 metering unit head is equipped as standard with a manual row cut-off.
The manual row cut-off can be optionally replaced by an electric clutch. Coupled to the seed monitor, it can automatically manage the row cut-off for the sprayer passages.

The MECA V4 metering units are mounted on ball bearings. Two types of self-cleaning front wheels can equipp the MECA V4 metering units:

- One 260 x 100 wheel with adjustable clod removers for planting in conventional soil preparation conditions
- Two 285 x 65 wheels with double disc openers for planting in trashy or superficially prepared soils

The seed placement is ensured by a rounded shoe. The shoe tip is interchangeable.
If necessary, carbide tip shoes are available on option.

A stand on each metering unit prevents the shoe from being clogged up.

Once in the ground, the seed is pressed with an independent stainless steel intermediate press wheel equipped with a plastic scraper. This wheel has also a pressure adjustment and can be retracted.

The furrow closure is provided by two V self-cleaning press wheels. Ground pressure of the wheels is adjustable. These wheels are mounted on reinforced bearings and with rounded scrapers.

The hopper in high resistance, transparent plastic has a capacity of 8 litres.

The depth adjustment is rapid thanks to a lever on the “Front depth control” metering unit or a knob on the “Balancing system” metering unit. The adjustment by lever offers a precise 5mm adjustment. On the “Balancing” metering units the precision of adjustment is in millimetres.

One motor for each metering unit

• Maintenance-free
• Takes up little space
• Electric motor placed in an elevated position and so protected from shocks and dust

Controls the seed drop and the distance between the seeds

The metering box made from cast aluminium is very simple and requires no adjustment.

A stainless steel insert is fixed on the whole inner periphery of the metering box. This highly resistant and interchangeable insert ensures long life for the metering box.

Once the seeds are ejected from the disc, the brush cleans the holes for an always optimal selection of the following seeds.

To avoid clogging of the holes, an ejector removes the seeds that may remain trapped in the holes of the disc.

The selection plate is specific to the type of seeds. Several selection plates are available for different types of seeds.

The distribution by vertical rotor has an internal power supply of seeds. The large diameter disc (250mm) provides exceptional placement accuracy, even at high speeds.
For all sizes of standard pelleted sugarbeet and chicory seeds.

Stainless steel protection cover of the disc. It ensures the protection of the disc against clods, stones and trash.

Planting of the seed is ensured by a shoe with interchangeable tip. Its tilting allows quick access to metering box.

The design of the metering box needs a minimum of seeds. A hatch allows emptying of the metering box.
