Viticulture: new Gregoire straddle tractors G4.210 and G4.220

G4, the new straddle tractor from the Grégoire brand, features, among other things, autonomous tool recognition.
According to the brand, this gives it a level of comfort and efficiency never achieved before.

Designed for year-round use, this new straddle tractor can be fitted with the Grégoire harvesting unit, the new ISO ULTIMA spraying unit, and the Grégoire front, mid-mounted and rear tool carriers.

It even includes a 3-point rear linkage system and a trailer hitch. Designed for the narrow vineyard market, G4 comes in two models: G4.210 for vineyards from 1m and G4.220 for vineyards from 1,20 m.

According to Grégoire, here are the strengths of the two new straddle tractor models G4.210 and G4.220 on the narrow vineyard market:

- New high-visibility driving environment: a new design offering a feeling of space and an unrivaled field of vision. Exemplary driving comfort with air conditioning, seat-mounted controls, a high-comfort air suspension seat, a refrigerated compartment and a Bluetooth radio system.

- A new steering system: a Grégoire exclusive offering a completely unobstructed view of the front wheels as well as the front and mid-mounted tools.

- A color terminal bringing together all the information and settings useful to the driver and serving as a display for the cameras.

- A system for autonomous recognition of the tools connected to the G4 tractor, with automatic updates of the pictograms and reassignment of the controls.

It also features an ultra-fast system for hitching and unhitching the harvesting module, the ISO ULTIMA spraying unit and the entire range of Grégoire tool carriers.

- Linear neutral-point joystick (Grégoire patent) that triples the number of possible functions. All machine functions can thus be controlled without letting go of the joystick. It also makes it possible to control end-of-row sequences.

- Engine speed management system at the headland. The driver can choose to automatically drop the engine speed to a predefined level in order to reduce consumption and noise. The engine returns to its initial speed as soon as the main component is restarted.

- Combined and automatic engine speed management according to user demand.

The joystick becomes a forward-travel control. It is no longer necessary to maintain maximum engine speed when traveling on the road, resulting in optimized consumption, noise level and driving comfort.

It should be noted that G4 is the only straddle tractor in its segment to be road-approved for a speed of 30km/h. For even more comfort, the front axle is fitted with nitrogen-ball suspension.

- Semi-automatic slope control management: the machine levels itself with a simple impulse on the ?G Multi Drive?.

- The harvesting head has pendulum suspension relative to the machine chassis. Shaking and harvesting are carried out very gently thanks to optimized row tracking.
