At Agritechnica 2013, Pöttinger unveiled a revised range of semi-mounted centre-delivery rakes with the Top 612 C (5,90 m wide), the Top 702 C (6,45 to 7,05 m) and the Top 762 C (6,90 to 7,60 m). The manufacturer has fitted these new rakes with the new TopTech rotor. They feature rotors from 2,80 to 3,30 m in diameter and up to 13 tine arms. In addition, Pöttinger offers mechanical or hydraulic working width adjustment on the Top 702 C and the Top 762 C, with a direct effect on the width of the windrow. These new features are already available in the Pöttinger catalogue.
The Pöttinger Top 612 C, Top 702 C and Top 762 C are fitted with TopTech rotors with a diameter of 2,80 m (11 tine arms), 3,07 m (11 tine arms) and 3,30 m (13 tine arms) respectively. According to the Austrian manufacturer, the 702 C and 762 C models have the largest cams on the market at 420 mm (compared with 350 mm on the Top 612 C). In this way, Pöttinger reduces the slope of the cam track for smoother rotation of the tine arms. These arms are fixed independently to the rotor by two bolts, so they can be replaced quickly in case of damage.
For transport, the two rotors fold hydraulically to the vertical, with dimensions of less than 4 m high and 2,55 m wide.
Three mechanical or hydraulic variants for working width adjustment
On the Top 702 C and Top 762 C models, Pöttinger offers 3 ways of adjusting the spacing between the two rotors: mechanical tie rods, ?short? mechanical tie rods or hydraulic cylinders.
A choice of rotor axle combinations
To carry the rotors and control their working height, Pöttinger offers a 3-wheel axle as standard (1 front wheel and two rear wheels). Optionally, the user can choose the 5-wheel version (1 front wheel and 2 pairs of tandem wheels at the rear) for better ground tracking. In addition to this rotor axle, the Austrian manufacturer offers the single-wheel ?Multitast? gauge, already known on the wider versions of the Top rakes (852 C S-line and 972 C S-line).
A shortened chassis for steering angles of 73°
The semi-mounted chassis of the Top rakes is connected to the tractor by an inverted ?U? hitch. The main beam has been shortened by 20 cm compared with the previous Top 600 models. Thanks to the combination of a shorter beam and a ?wide-angle? PTO shaft, the steering angle reaches 73° on the new Top 612 C, 702 C and 762 C models.
In addition, the wheels of the rear axle (260/70 R15,3) pivot to follow the tractor. A linkage system allows the rake to follow the path of the tractor without cutting the corner or drifting outwards. As standard, Pöttinger offers an axle 2,55 m wide. To meet the need for more stability, the brand optionally fits an axle 2,90 m wide.
* The TopTech Plus rotor, already used on the rakes of the C-S Line range, has continued to evolve. The cam is adjustable to suit different quantities and qualities of forage. The oversized angle gearbox is completely sealed and lubricated with fluid grease. The large crown wheel diameter ensures long service life and quiet operation.
