With TOP A side rakes you benefit from the highest flexibility. On our rotary rakes, a ride range of working widths is possible thanks to the ingenious steering system on the rear rotor.
Obstacles and wedge-shaped fields are no problem.
The size of the swath can be optimally adapted to match the size of the next machine.
The forage can be raked into one or two swaths.
Our three models reach a working width of up to 6.30 m / 6.90 m / 7.80 m in double swath mode.
Thanks to their light weight, these rakes enable large working widths with small tractors and are therefore extremely cost effective.
At the same time, the heavy duty frame is designed for the toughest operating conditions.
The rear rotor, which is connected to the front one by a flexible frame, can be pivoted to the left or right by a hydraulic cylinder. This makes it possible to rake a double swath or two single swaths. One double-acting spool valve is needed for this.
When raking a double swath, the rear rotor is pivoted to the left. It takes over the forage from the front rotor. The optional front swath curtain is raised.
The working width can be easily varied hydraulically by steering the rear rotor. Obstacles and wedge-shaped fields are no problem.
If the rear rotor is swivelled to the right and the front swath curtain is folded down, each rotor produces its own swath. This makes it possible to form two smaller night swaths, or two normal-sized swaths in the case of very high forage volumes.
The frame for the second rotor is mounted 650 mm in front of the axis of the first rotor. This ensures the rake stays on track when working on slopes and also provides enough overlap when cornering. At the headland, the hydraulic working width adjustment system can also be used to pivot the rotor for perfect manoeuvrability.
The CURVETECH automatic steering system for the rear rotor is available as an option on the TOP 632 A. Two hydraulic cylinders work together to steer the rear rotor. An additional linkage between the front pivot point of the main frame and the hydraulic cylinder ensures optimised overlap of the two rotor units when cornering. Maximum utilisation of the working width is guaranteed.
The TOP 632 A CURVETECH gives you maximum operating convenience thanks to the standard BASIC CONTROL pre-select system. You can easily choose between single swath, double swath, manoeuvring and transport modes. The two hydraulic cylinders for steering the rear rotor are controlled automatically so that when the spool valve is actuated, the rear rotor swings out on the correct side.
The rear rotor is mounted in gimbals, which together with the freedom of movement in the frame joints allows excellent three-dimensional ground tracking of each rotor. Vertical freedom of movement is provided by a joint directly behind the angular gearbox. Transverse movement of the rear rotor unit is enabled by a pivot bearing mounted within the frame itself, and by a universal joint between the rear frame beam and the rotor unit.
TOP A rakes are equipped with tandem axles as standard. The wide chassis provides first class ground tracking and the best stability on slopes. Optional AS tyres on a wider axle provide even more grip on steep ground. With the optional double jockey wheels inside the rear rotor arc, even more precise ground tracking is possible. The best quality forage is therefore guaranteed.
One single-acting connection to the tractor hydraulics is all that you need for lifting. Stepping valves provide more convenient operation for raising and lowering the rotors. The front rotor is always lifted and lowered first. This ensures tidy work at the headland without damaging the existing swaths. With a ground clearance of 50 cm, you can drive over large swaths confidently.
The drawbar is equipped with a large support plate to provide you with extra stability on steep ground and when cornering. Various types of mounting are available.
Lower linkage mounting with integrated mounting rail
Parallel lifting drawbar for the tractor pick-up hitch
High drawbar with 40 mm towing eye (TOP 632 A)
With optional hydraulic swath curtain lifting, the TOP 632 A has a transport width of less than 3.0 m without having to leave the tractor cab. The tine arms do not need to be removed.
You simply use the tandem axles as a transport chassis. The 18.5 x 8.50-8 flotation tyres also enable safe and smooth road transport even at high speeds. Both axles remain in contact with the ground and ensure first-class handling thanks to the tandem effect. The optional dual jockey wheel inside the rotor arc is lifted automatically for road transport. Warning signs and LED road lights are standard.
