The semi-automatic line consists of the GREEN 550/4, GREEN 650/5L and SPRING 650/8 models. The GREEN 550/4 is the perfect solution for those approaching semi-automatic harvesting for the first time. The model stands out for its versatility, simplicity, robustness and price. It is the ideal solution for small plots of land (0.5-1.5), and the possibility of working in semi-automatic mode allows considerable ease of manoeuvre. The GREEN 650/5L has always been the most popular model because it guarantees simple, reliable and gentle harvesting, regardless of the characteristics of the soil. It is equipped with independent belt speed adjustment, steering wheels, side sorting channels, platforms on both sides for 6 operators and hydraulic rear forklift prepared for optional rotation to allow off-row unloading in bins, crates and sacks. The machine is perfect for harvesting softer crops, such as sweet potatoes, and is ideal for extensions of 5-6 hectares. The SPRING 650/8 model stands out for the versatility of its harvesting process. The machine is equipped with a curl belt that, combined with the action of a rotating roller, effectively cleans the crop. As it is equipped with two independent sorting belts, it is perfect for working in all conditions: in the case of loose soil, the harvesting process will be automatic and the belts will run in parallel, unloading at the back; in the case of clayey soil or, in general, in the presence of numerous stones, reversing the direction of the belts will allow the operators to manually select the potatoes and place them on the second sorting belt which will unload at the back, making the stones unload on the ground from the first belt at the front. The machine is recommended for harvesting medium to mature crops and for extensions of 10 hectares.
