Rapid stubble ploughing
and ultra-simplified maintenance.
Residue DecompositionThe Normandie evenly distributes crop residues and organic matter in the surface layer. |
Self-seedingWhen the Normandie passes with a depth no more than 5 cm, it creates conditions conducive to weed emergence by encouraging soil-seed contact. |
Pest controlThe Normandie destroys adult pests and eggs on the surface. |
Soil warmingAll seeds need balanced conditions to germinate: water, air, heat and soil. With each pass, the Normandie brings moisture from the lower layer and aerates the soil. The soil then warms in the sun. |
Soil-seed contactGermination begins when the seed absorbs a large amount of water. For the seed to have access to water, it is important that soil clods surrounding the seed are not too coarse. The seed can take water from the soil when it has good contact with the soil. |
Erosion controlThe combined actions of the discs and the Normandie rollers provide excellent soil structuring. By breaking open potential surface crusts, water infiltration and retention capacity is increased. |
Impak rollerRow of roller wheels 540 mm diameter. Excellent finish in wet conditions, it gives even ground consolidation. The scrapers prevent soil build up and level between the roller wheel arches. |
Emopak V RollerFlanged, contoured and notched roller wheels. Its mass makes it capable of good consolidation, leading to excellent in-line finishing. Well suited for self-seeding as it offers perfect soil-seed contact. It excels in dry, stony cloddy soils. |
Packer RollerRoller tube with ridges. Ideal for breaking and consolidating medium and large clods, it is used in seedbed preparation. Suitable for wet or clay conditions, its scrapers prevent the clogging. |
Square bar rollerAggressive on plant residues, it allows you to create a uniform mulch and accelerate stubble disintegration by maintaining a good level of moisture in the soil. It is lightweight and economical. |
Double square bar rollerTwice as active, it destroys the most resistant plant residues and leaves behind an excellent finish. The unit is mounted on a pivot to conform to the shape of the land. |

Optimal safety with any disc type and in any condition. Elastomer packing cushions and absorbs shocks and twists to the disc arms. Its flat edge perfectly matches the disc train support tube. It thus avoids any lateral and vertical movement on the tube. Exclusive to GB Group, this guarantees long service life. ![]() |
|
The disc arms, permanently fixed by 6 bolts, are shaped for a better passage in plant debris and to avoid the accumulation of earth. The reinforced arm shape ensures rigidity and avoids deformations at high speed. The bearings, guaranteed for 5 years, are maintenance-free and give you peace of mind to concentrate on your work. ![]() |

Unlike some competitors who leave the choice of angle open, Grégoire Besson brings you a unique yet perfect solution.
On all Normandie models, the angle of attack is 13.3 degrees. This allows the stubble harrow to attack residues or vegetation effectively. The angle was not chosen randomly, it is the result of a long series of tests and is the best trade-off between efficiency and fuel consumption.
The 5.2 degrees entry combined with the curve of the disk allows the entire working surface to be sliced even at very shallow depths.
At Grégoire Besson, we understand that mechanisation represents a significant financial burden for users and so the Normandie provides very low costs per hectare: fuel economy, low wear parts, working efficiency.
