Tronic – mechanical spreading disc drive
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.
"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."
