The seal principle is based on the unique catching paddle train system, which is now equipped with a pneumatic membrane.

The controlled air pressure in the membrane has a number of advantages:

- Optimised ground seal : no loss of grapes onto ground

- Ease of use: valves allow straightforward control of air pressure with the membrane

- Adapts perfectly to the effort of the paddle, in accordance with the characteristics of the vine: respects each vine and the vineyard as a whole, whilst protecting against plant disease and death

- Allows the user to control the life of the paddle: possibility of increasing or reducing the rigidity of the paddles, reduced maintenance costs

- No maintenance required: factory installation of the pneumatic paddle train, removal of stiffeners

- Can be adapted to existing machines: pneumatic paddle train can be fitted on existing GRÉGOIRE machines

Combined with a long seal area, the new pneumatic paddle train ensures high work output for all GRÉGOIRE Grape Harvester machines.

The advantages are the following:

- Perfect visibility at the front of the machine: the driver has an unhindered view of the front wheels, the upper part of the row being worked, the entrance to the collection tunnel, and even the front implement (in the case of multi-purpose use).

- Soft and effortless steering: the steering control is effortless and particularly flexible. This allows for high-precision manoeuvrability.

- Exceptional handling: the rocker-free steering system also provides the G7.200 with excellent manoeuvrability. With a turning circle of less than 3.60 m, the tractor can even be easily manoeuvred in the most compact and difficult plots. Even "sharp corners" are rendered more accessible, thus preventing loss of time during work activities.

- Strength and durability: finally, the kinematics of the front wheels allows the operator to change directions with no need to slow down at the end of the row (if the topography permits). The manoeuvring times are optimised, and the work site's potential is significantly increased.

Together with the central GRÉGOIRE cabin, the new rocker-free steering system renders the G7.200 exceptional manoeuvrable.

For those who don't recall, following 24 hours of work activities, during which the darkness and the rain put a significant strain on the teams' morale, a G8.270 'ÉLITE set a series of exceptional records:24 hours of non-stop harvesting, 11.7 L/h (9.8 L/ha) consumed, 28.28 hectares harvested, equal to 1.18 ha/h at an average of 6.5 km/h.

This film, which lasts 10 minutes, was created by Bruno Boucard and produced by GRÉGOIRE. The film's protagonists are the teams of the Boinaud company and GRÉGOIRE. Filmed in Bois d'Angeac, at the distillery's historic location in Charente, 25 people collaborated for 24 hours non-stop to achieve a record grape harvest. All this served as a confirmation of the characteristics of GRÉGOIRE materials (reliability, durability, and low usage costs), while at the same time highlighting our innovations (driving comfort, motor efficiency, and ease of adjustments).
