simplicity in all aspects

Clean hitching

On all models, you have a simple headstock with cross beams where you adjust the plumb mechanically by a screw. You can also manually lock the plough for transport mode. Grégoire Besson Prima 70 avant

Robust beams

All Prima beams are reinforced (except Prima 40). This gives them greater resistance to twisting, bending and impacts. Grégoire Besson Prima 70 avant

Multi-position Adjustment

To adjust the working width, a pin-and-hole system allows you to change the angle of each element. You can then work from 12 to 22’’ depending on the inter-body spacing and Prima model. Grégoire Besson Prima 70 avant

Prima 70 Suspension

As an option on this model, you can choose a suspended headstock in order to minimise the load of your tractor’s lift. You gain in comfort and your equipment lasts longer. Grégoire Besson Prima 70 avant

Simple adjustments

You adjust the vertical plumb with a stop screw. You set the tilt using a mechanical tie rod. You control the depth by the wheel and the coupling.
Your plough is set. Grégoire Besson Prima 70 avant

Hydraulic realignment

When in-furrow models with more than 4 bodies are turned, a hydraulic cylinder realigns the plough so that it does not touch the ground. Grégoire Besson Prima 70 avant

Prima 40, 50 & 70 in-furrow offset

You can adjust your offset by means of a multi-position system. This means you can have very short and strong mounted ploughs. It transfers as much load as possible to the tractor. Grip is improved and you use less fuel. Grégoire Besson Prima 70 avant

Prima 70 on-land & 80 on-land offset

The offset management on these two models allows you to work on-land with tractor tracks up to 3.5 m wide. Grégoire Besson Prima 70 avant

Adding or removing a body

Do you plan to change your tractor one day? For one with higher power? Or lower? Remember, you can easily add or remove a ploughing body. Don’t forget to specify this when configuring your mounted plough. This means that you do not have to change ploughs if you change tractors. Grégoire Besson Prima 70 avant

Available in front plough

The Prima 70 plough is also available as a push plough for hitching onto the front linkage of the tractor. It brings a load transfer on the front and improves the grip of your tractor. Grégoire Besson Prima 70 avant

ploughing in-furrow or ploughing on-land?

In-furrow

If your tractor has with single wheels, and you plough at less than 35 cm, in-furrow ploughs are made for you.

By placing the tractor wheels in the furrow, ploughing is easier. The wheels can get a good grip on the bottom of the furrow. Traction is then at its best, especially in wet conditions. Slippage is limited and you save fuel. Grégoire Besson Prima 70 avant

On-land

On the other hand, on-land ploughs are more suitable if your tractor is equipped with tracks, twin wheels or wheels over 710 mm wide.

By ploughing on-land, you will reduce tyre wear, especially if you have flinty soil.

Sometimes, our customers choose an on-land plough even though their tractor is equipped with single wheels because they prefer to use their GPS guidance system. Grégoire Besson Prima 70 avant

shear bolt or hydraulic safety system?

Shear bolt

For stone-free soils, choose shear bolt safety.

When the ploughing element hits an obstacle (stone, root...), the shear bolt breaks. The entire element rotates and allows the foreign body to pass under the plough.

The shearing noise alerts you, so you stop the tractor, get off and extract the bolt that gave way. All you have to do is replace the shear bolt. That’s it, you’re ready to plough again.

Grégoire Besson Prima 70 avant

For light and sandy soils without any stones, we recommend light soil shear bolts. The way it works is the same. On the other hand, there are 2 bolts for each ploughing element, one per body.

Shear bolt safety extends the life of your equipment: the beam is better protected against buckling and it reduces the forces exerted on your tractor.

Safety shear bolts resist forces between 4.2 and 6 tonnes at the tip of the body, depending on the model. Grégoire Besson Prima 70 avant

Continuous Hydraulics

If your fields have stony soil, without question you need to choose the continuous hydraulic safety version.

With this safety system, if a ploughing body hits a stone or any other foreign body, the entire element lifts up and clears the obstacle. Once it has passed, the hydraulic system returns the element to its place. It is held in position by the 4 hinges that it rests on.

there is no need to get out of the tractor cab. You don’t have worry about stones, you can just concentrate on ploughing. You stay productive and protect your investment. Grégoire Besson Prima 70 avant

In very stony and clayey soils, we offer continuous hydraulic safety but with high capacity. The way it works is very similar but it is more suitable for this type of soil.

Because of this small difference, the safety system will not activate where your soil is really compacted so your ploughing will be perfectly even.

Whichever type of hydraulic safety device you choose, there are three cylinder diameters to choose from: standard, large or very large diameter. If you have heavy soil, choose a large diameter. If you are not sure, ask for expert advice from Grégoire Besson. Grégoire Besson Prima 70 avant

With the objective of adapting hydraulic safety systems to the different types of soil around the world, you can also choose between 100 bar or 150 bar pressure accumulators. The denser, heavier or more compacted your soil, the higher the pressure we recommend.

Specifically developed for the Israeli market, the EXTREME high capacity continuous safety system is designed with longer axle spacings. It has no lateral travel and extremely high tip resistance. It can only be fitted to the Prima 80 on-land plough. This safety system is an unrivelled success with Israeli farmers. Grégoire Besson Prima 70 avant

skimmers, trash boards, disc coulters, etc.

Mixed Skimmer

The short coulter and mouldboard make this combination very versatile. It is suitable for 80% of applications. Grégoire Besson Prima 70 avant

Plastic Mixed Skimmer

The plastic mouldboard enables the surface to be scalped, even with very sticky soils. Grégoire Besson Prima 70 avant

Universal Skimmer

Its wider coulter and longer mouldboard enable this combination to handle larger volumes of plants than the mixed skimmer. Grégoire Besson Prima 70 avant

Maize Skimmer

The high mouldboard guarantees a smooth passage through tall plants such as corn, sunflower, etc. Grégoire Besson Prima 70 avant

Pasture Skimmer

The very long mouldboard enables it to turn over very dense root systems such as those found in grasslands. Grégoire Besson Prima 70 avant

Trashboard

Used mainly in winter ploughing, it positions the residues of large plants vertically to improve water infiltration. Grégoire Besson Prima 70 avant

Spring-mounted Disc Coulter

Suitable for stony soils. It cuts plants and soil 10 cm in front of the body. It creates a clean furrow base and wall that provides better grip to the tractor. Grégoire Besson Prima 70 avant

Bolted Disc Coulter

Suitable for lightly stony soils. It cuts plants and soil 10 cm in front of the body. It creates a clean furrow base and wall that provides better grip to the tractor. Grégoire Besson Prima 70 avant

Knife coulter

It cuts a strip of earth to stop the furrow wall attaching to the mouldboard and helps prevent it from crumbling. Grégoire Besson Prima 70 avant

Mouldboard extension

The mouldboard extension positions the earth for precise finishing. It limits wear at the end of the mouldboard. Grégoire Besson Prima 70 avant

Spike Sub-soiler

It loosens the soil to a depth of 15 cm under the plough body. It promotes water infiltration, gas exchange and root exploration. Grégoire Besson Prima 70 avant
