VOLTO trailed tedders

Pure power
 

The 29.3° rear-angled connection also has a positive impact on crop delivery. Like the angled spreading blades of a fertiliser spreader, this configuration ensures a wider and more even distribution of the harvested crop, for an optimal spread pattern. This fertiliser spreader effect is further supported by tine tension release in the direction of the winding, to spread the crop over the entire width.

To cushion loads, the tines have five windings. The material thickness of 9.5 mm still provides enough rigidity for a clean raking result. To protect animals and following harvesting machinery, each spreader arm is equipped with a tine loss guard. These guards prevent tines from coming away in the event of a breakage, and their trapezoid shape prevents the forage from becoming wrapped around the spreader arm.

The highest forces acting during tedding are exerted on the spreader arms. They are therefore made from rounded tubing for high torsion resistance, bolted to the rotor plate, and further stabilised with a support ring with recesses.

To adapt the machine to the harvesting conditions, the spreading angle can be set over a range from 12° to 18° depending on the model. The tines can also be adjusted forwards or backwards by 7°, allowing you to fine-tune your desired spreading pattern.

To produce high-quality forage, the harvested crop must be dried out evenly. The tines on VOLTO machines are therefore equipped with fingers of equal length. These pick up the crop in layers, and ensure that it is mixed thoroughly. The result is a homogeneous spreading pattern, and rapid drying of the harvested crop.

On VOLTO machines, power is transferred via the 
PERMALINK finger clutch, which ensures reliable transfer of power in all operational conditions. The innovative design additionally enables folding movements of up to 180°, allowing retraction to a compact transport position.

When working with hay, forming overnight or temporary swaths is often advisable, particularly when harvesting time frames are tight. The hay then absorbs less moisture overnight, and so dries faster the following day. This operation is carried out with the night swathing gearbox, reducing the rotor speed by one third. The harvested crop is formed into several small swaths.

The new PERMALINK HD finger clutch is specially designed to deliver maximum efficiency with working widths of up to 15.10 m. The large and extremely robust fingers ensure a reliable force-fit connection in all positions. With the enlarged wear surface and maintenance-free design, CLAAS guarantees lasting safety and performance.

Solid box sections give VOLTO machines the endurance they require in the field. These feature a wall thickness of 8.00 mm and are angled at 45° for effective absorption of torsional forces and enduring operational reliability. Furthermore, forces acting on the chassis are absorbed by solid cast-iron joints with a double-shear connection.

Depending on model, headland lift comes as standard or is available as an option in the VOLTO. Headland lift stabilises the outer rotors to ensure a comfortable ride at the headland.

The T models are fitted with a short drawbar and a road transport chassis behind the rotors. This ensures a narrow turning circle and simple, compact handling in the field, while the long wheelbase allows speeds of up to 40 km/h on the road.

When the single-acting spool valve is moved to float position, trailing steering is automatically activated in working position. This eliminates the need to raise into headland position during tight turning manoeuvres – making even more efficient and soil-friendly use of the enormous working width of up to 15.10 m.

Up to 14 small rotors ensure optimal ground-contour following – after all, every blade of grass counts and soil has no place in the forage.

The large trailed tedders with road transport chassis behave like compact mounted models in the field because the rotors in float position run close to the chassis, which acts as a guide wheel.
