BOSS HD trailed 4/7,5 m

3 to 12 m

16,7 cm / 18,75 cm / 20 cm / 25 cm

Up to 400 kg/ha

The double angled disc of the BOSS drill works by snatching. Thanks to his conception, it always try to get more and more in the ground according to speed and depth. The faster and the deeper you you, the less pressure you’ll need.

THE SEED DRILL THAT YOU ACCOMPANIED AT YOUR RHYTHM

Conservation agriculture is at the heart of our concerns.
This no-till drill is the result of a long period of collaboration with experienced no-till drill farmers. The challenge was to imagine a drill allowing us to overcome the difficulties encountered with actual no-till drill: Residue in the furrow, difficulty in penetrating hard/dry soil and difficulty in closing seed furrow in wet conditions.

The range is large and scalable to answer everyone’s need: from 3 to 12m, with no or up to
4 dosing unit, 16.7 cm,18.75 cm, 20 cm or 25 cm row spacings

COULD THERE BE A LINK ?

Thanks to both field testing and 3D modelling we have calculated different simulations using both existing and new designs of disc coulter. We have considered the soil as a known
material to see if any correlations appear.

The red zones show compaction, blue show little compaction.

Red zones have confirmed the two difficulties of penetrating in the dry versus closing a furrow in the wet. It has also shown how a lack of row cleaners can cause more severe compaction when planting. More residue means a greater surface area pushing down and therefore a wider and larger compacted area.

It is simple to understand that when any seed germinates it first anchors itself with roots and begins nutrient and water uptake, so it is vital that this first stage of life is a success.

PRINCIPLE OF THE UNDERCUT

A concept that caught our eye in Australia was the double angled disc, also called the undercut disc. This solves many problems associated with no till seeding.

When we run analysis on the double angled disc we found that the down pressure requirement was reduced and more manageable versus seed furrow compaction.

THE DISC & SEEDBOOT FOR A PERFECT MARRIAGE

The seedboot is placed in shadow of the disc. This allows excellent performance in wet sticky conditions. The seedboot is positioned to never touch the soil and such that the front of the disc is the only soil contact point. The wet soil is cleaned by an active scraper (the side wheel). The less static parts in contact with the soil results in far less risk of plugging/bunging. The concept allows for drilling in the same direction as last year’s corn rows. If you do not need to run at an angle to last year’s crop, there is a better chance of implementing practices such as CTF (controlled traffic farming).
No angle generally means a smoother travel and better seed placement improving emergence and therefore yields.
