The new GREGOIRE range of grape harvesting machines incorporates an innovative principle for the management of on-board systems (engine, transmission, hydraulics etc.). This offers greater comfort to the user, as well as exclusive features for optimizing yield and efficiency.

The Multi Drive joystick is equipped with a linear neutral position system (patented by GREGOIRE) which allows the number of functions performed to be tripled. All operations needed to operate the machine can be performed without letting go of the joystick.

The user interface systems - View Master colour touch screen, Control Master adjustment console and Multi Drive joystick - are fitted with a recognition system which allows, depending on the equipment present (harvesting head, sprayer, vine maintenance tools), for:

1. the automatic updating of commands for optimum ergonomics, comfort and performance;
2. automatic updating of the command pictograms, making it intuitive and easy to use;
3. management of the specific functions of each tool, without the need for a control box in the cabin. The most striking example is the steering of the Quattro ramp on a Multiflow cell (automatic ground tracking and end-of-row sequencing).

The Grégoire system also comes with exclusive features designed to reduce costs, increase environmental friendliness and enhance performance:

1. Eco Drive: end-of-row manoeuvres at low revs. Generally speaking, full power is not required for this operation.
2. Auto Drive: combined management of the engine rating and pump displacement in road mode. Allows for a reduction in the engine rating, sound levels and consumption during transport.
3. Auto Level: automatic resetting of the system.
