The Spirit 6200 uses state-of-the-art technology (in the steering system) and inventive separating techniques to provide a perfect harvesting quality while maximizing the capacity.
Plastic diabolos on the AVR digging unit allow accurate control of the harvesting depth. The plastic material reduces soil clogging and is stone-resistant. Large haulm intake rollers and cutting discs prevent haulm blockages. The harvesting depth can easily be adjusted using a central crank spindle. An accumulator and optional electro-hydraulic ground pressure controlsystem ensure minimal pressure on the ridge.
The potatoes land on the digging web (light green). This 1,650 mm wide web is equipped with 2 star vibrators and is powered by highly durable and potato-friendly PUR drive wheels.
The potatoes are then transported to the 2nd sieving web (purplish pink) mounted under a haulm web (purplish blue). This is a very product-friendly and efficient way of removing the haulm. This system is therefore also ideally suited for harvesting while the haulm is still green.
The product flow then continues to the in-line pintlebelt (greenish blue) where soil, small clumps of earth and haulm are removed under retaining rollers, which direct the flow towards the transversal pintle belt (brown). A rotary comb positioned above the transversal pintle belt ensures the clumps of earth and stones are efficiently separated from the potatoes.
The clumps and stones fall onto the discharge belt (light blue) and the potatoes move to the picking-off table (dark green). Here, a last visual inspection can be conducted.
