Designed based on a long line of proven grape harvesters recognized for their picking quality. The GT3 is the new high-performance and innovative solution in Gregoire’s product range in tow behind harvesters. It retains the core value of the brand while the use of proven technology to make it operator friendly with low operating costs.

In terms of technical innovation, GT3 is the first ISOBUS towed harvester available on the market reducing the need for an extra screen in the tractor. The GT3 has an impressive 2000 litre bins on each side, meaning it is the largest carrying capacity on the market. Coupled with the newly designed wide-angle drawbar, connected direct to the tractor, boosting manoeuvrability whilst still maintaining stability. This makes it a very appealing option to both growers and contractors.

If you are looking for a harvester, with proven technology, large carrying capacity and low running cost, we have the solution: GT3!


  • Minimum row spacing of 1.7 meters
  • Wide Angle, Sensing Draw Bar
  • MAXIflow Cleaning System for bottom fans
  • Market Leading Bin Capacity
  • AUTOlevel and AUTOheight Management
  • First fully ISOBUS optioned Towed Harvester




GT3 is the most ergonomically designed solution in terms of pull type harvesters. All settings, information are gathered at a unique control point for more efficiency. Every tool speed (picking head, fans, belts,…) is adjusted in real time according to settings, giving consistence working speeds and best picking results. Headland sequencing programs, which are fully adjustable and customizable are available, giving ease of row entry and exit. Color camera, inclinometer, bins sensor are also GT3 standard equipment that benefit to picking efficiency.


Draw bar

Harvester direct coupling on the tractor draw bar provides the stability and manoeuvrability of the machine in all conditions. With its compact design, it perfectly adapts to all tractors and allows machine guidance and it’s height adjustment whilst maintaining stability. The wide-angle drawbar helps manoeuvring even in the shortest headlands. The sensor integrated to the drawbar will automatically manage machine driving assistance based on tractor traction.


Large Bin Capacity

GT3 lateral stainless steel bins offer the largest storage capacity available on the market, with the onboard carrying capacity is now 4000L. Dumping time is less, and productivity is increased.


Automatic ground drive management

GT3 is equipped with hydraulic wheel drive motors with an option to upgrade to larger motors for the steeper slopes. The new transmission management offers you a unique driving experience. Once transmission activated, the sensor fitted on the drawbar will adjust machine speed according to the tractor traction. Driving assistance needs are supplied by a load sensing pump. An OVERboost mode gives increase drive to cope with most difficult ground conditions. Transmission being fully automatic whatever the situation, allowing the driver to concentrate on the machine settings, and picking optimisation.


ARC2 picking head

Trellis care, picking quality and innovation have always been associated with the GREGOIRE ARC picking head. The new ARC2 picking head design is based on heritage. ARC2 is setting new GREGOIRE picking standards and compliments the new GT3 perfectly.


AUTOlevel & AUTOheight management

With a 700mm of levelling range, the GT3 can perform in the toughest conditions. A standard feature, AUTOlevel® allows you to correct the slope semi automatically, keeping the machine always level. The GT3 is equipped with an electronic height management. A working height and a dumping height can be programed and are quickly accessible with a simple click on the joystick. Road height is also available directly from the joystick when switching to road mode and thus machine levelling is synchronized. With this system you don’t have to worry about machine height.


Auto Ground Drive

The new transmission management offers you a unique driving experience. Once transmission activated, the sensor fitted on the drawbar will adjust machine speed according to the tractors requirements. This feature allows the driver to concentrate on machine operation, settings to achieve picking optimization The OVERboost mode gives the operator increased drive to cope with the most difficult ground conditions when they arrive.


Cleaning and sorting

The GREGOIRE harvest cleaning fan perform cleaning as soon as possible. This removes leaves and MOG (Materials others than grapes) before they get wet and heavy. Juice losses are minimized as bottom fans do not need work high speeds. To optimize the bottom fan efficiency GT3 is equipped with MAXflow system. 2 trapdoors located each side of main conveyor, underneath bottom fans, adjusts air intake to fans for an optimum MOG extraction. Trapdoor position and air intake can be adjusted in seconds depending of harvest conditions.



GT3 frame has been specifically developed to cope with the most demanding situations. Lightness and robustness have been our main focus to design the most streamlined frame possible.
