Pöttinger launches the TOP VT 6820 S and TOP VT 7620 S twin rotor rakes with side swath placement. Despite their low power requirement, the new machines are designed to rake large swaths. The TOP VT 6820 S achieves a working width of 6.80 m, while on the TOP VT 7620 it reaches 7.60 m. For even more capacity, Pöttinger added the new TOP VT 12540 C to the four-rotor range.
The angled tines of the TOP VT 6820 S and TOP VT 7620 S lift the crop slightly to ensure it is swept cleanly without dragging the forage across the ground. The standard five wheel chassis in combination with the rotor mounted in gimbals, ensures precision guidance of the tines over bumpy ground. As an option, a Multitast jockey wheel can be added to detect bumps ahead of the tines and lift the rotor accordingly. The raking height can be conveniently adjusted electro-hydraulically from the tractor cab, or manually using a hand crank. Likewise, the optional Multitast jockey wheel is adjusted automatically with the rotor chassis. Optional suspension springs also make sure that the rotors run smoothly in the working position.
Thanks to the dual swath function, night swaths can be formed and the machines can be used to rake hay and straw. This flexibility makes it possible to adapt to different harvesting conditions.
Convenient operation
One double-acting connection to the tractor hydraulics with float setting is needed for lifting the rotors. Both rotors are lifted and lowered one after the other via step sequence control. Thanks to the “Basic line” preselect system, the rotor units can also be lifted or lowered individually, which is particularly practical for leftover areas and raking along field boundaries.
The TOP rakes also feature high maneuverability: The steered chassis enables a turning angle of 80° so that the rake follows exactly in the tractor’s tracks. With a ground clearance of 50 cm, there is no problem driving over swaths. For a comfortable and safe ride during transport, the swath curtain folds in automatically, and the transport height remains under 4.0 meters, all without having to leave the cab.
For even more capacity, Pöttinger is also extending its range of four-rotor rakes with the new TOP VT 12540 C model, featuring an impressive compact design and high maneuverability. Thanks to its low weight, this rake can also be used safely on steep ground without compromising on performance.
The angled tines on the TOP VT 12540 C lift the crop slightly to ensure it is swept cleanly without dragging the forage across the ground. The rotor chassis can be supplied with four or five wheels, depending on requirements. Also here, together with the Multitast jockey wheel system, perfect adaptation to every bump in the ground is guaranteed. The raking height is adjusted manually using a hand crank. This also automatically adjusts the Multitast jockey wheel together with the rotor chassis.
Because the rotor is mounted in gimbals, the rake offers plenty of freedom of movement to ensure three-dimensional ground tracking. The front rotor units feature hydraulic weight alleviation and the rear units have mechanical suspension. This ensures uniform distribution of ground pressure.
Application flexibility and adaptability
The working width of the TOP VT 12540 C can be adjusted hydraulically whenever needed. Working in wedge-shaped fields and around obstacles such as electricity pylons or trees is no problem. All four rotors are driven mechanically by cardan shafts. Depending on which machine will be used to collect the harvest, the rear rotors can be shifted into in three positions without the need for tools. The width of the swath can be set between 1.20 and 2.00 m.
The rake is attached using a strong yoke. Double sided linkage lugs ensure an extended service life and allow a tight turning angle. The TOP VT 12540 C is supplied with the “Basicline” preselect system as standard. One double-acting spool valve controls the lifting and folding of all the rotors. Integrated stepping valves ensure that the front rotors are always lifted and lowered first. Using the Basic Control terminal, the front two rotors can be lifted and lowered together or separately. To adjust the working width, the two front rotors are operated together using a separate spool valve.
