The spreading disc drive
Mechanical or hydraulic, choose for yourself!
Tronic – mechanical spreading disc drive
Schematic representation of the mechanically driven ZA-V
On the mechanically driven ZA-V spreader, the spreading unit and agitator are driven by the PTO shaft. In this case, the spreader is protected from overload, as standard, by a universal drive shaft with friction coupling. The input speed from the tractor PTO is transmitted via the central gearbox resulting in an increased spreading disc speed. This allows spreading at low engine revs across the maximum working width.
- With mechanically driven spreaders, between two and eight part-width sections are switchable, depending on the operator terminal.
- Robust drive with a fuel-efficient gear ratio of 1:1.33
- Standard PTO shaft with a friction clutch provides protection against overload
"Simple and cost-effective part-width section control. Even with the spread rate reduction system of the ZA-V, good results can be achieved at the common working widths."

Hydro – hydraulic spreading disc drive
Schematic representation of the hydraulically driven ZA-V
The hydraulically driven ZA-V Hydro spreader enables operation at different spreading disc speeds, irrespective of the tractor’s engine revs. In this way, extremely comfortable and precise spreading is possible, and side, border or water course spreading can be activated independently to each side. The driver can conveniently switch between these separate functions whilst on the move. If the pre-set speed is not suitable for precise side spreading, it can also be adjusted via the terminal during operation. These changes are automatically saved in the terminal for the respective border situation.
- The side-independent regulation of the spreading disc speed permits even more precise spreading on wedge-shaped fields. Up to 16 part-width sections are possible in combination with SectionControl.
- With a pressure filter as standard
"In addition to fertiliser-saving, easily interchangeable and adjustable spreading at the field’s border, the ZA-V Hydro also provides the benefit that this spreader operates completely independently of the tractor engine speed, thus saving fuel."
