Spreading disc drive | Spreading system


The spreading disc drive: mechanical drive

On the mechanically-driven ZA-V spreaders, the spreading unit and also the agitator are driven via the PTO shaft. Here the spreader is, as standard, protected from overload via a friction clutch on the PTO shaft. The input speed from the tractor PTO is transmitted via the central gearbox resulting in an increased spreading disc speed. This allows fuel-saving fertilisation 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.

The spreading disc drive: Hydraulic drive

The hydraulically-driven ZA-V Hydro spreader makes operation possible with different spreading disc speeds, irrespective of the engine speed of the tractor. In this way a particularly comfortable and precise spreading is possible and side, border or water course spreading can be activated independently to each side. The switching over between these individual functions is convenient and possible on the move. If the pre-set speed for spreading at the field border is not precise enough, then this can also be adjusted via the terminal on the move.

With hydraulic spreading disc drive, up to 16 part-width sections can be actuated.

Spreading system with Soft Ballistic System

Due to its large aperture, the ultra-modern spreading system on the ZA-V can achieve application rates of up to 390 kg/min. The hopper tip, which tapers down to the shutter slide, prevents any residues being left making it easy to clean.

The quantity-effect free aperture is positioned freely above the spreading disc. The position is very close to the centre of the spreading disc offering the advantage that the fertiliser is taken up extremely gently by the spreading discs at the lowest circumferential speed. The fertiliser is then accelerated very gently. The spread pattern is maintained at all application rates and at all forward speeds and is completely independent to the spread rate.

On ZA-V spreaders, the entire spreading system is made from stainless steel and high-quality glass-fibre reinforced plastic and thus provides a long service life and a high resale value.

Spreading discs with QuickSet

Only 3 pairs of spreading discs cover the entire working range from 10 m to 36 m. The working width is simply, quickly and safely adjusted via the spreading vane position. Setting of the spreading vanes is carried out without any tools via the QuickSet adjustment system.

The standard spreading disc speed is at a fertiliser-protecting 720 rpm.

With their special shape, and several feed-on points at both the upper and lower end of the spreading vane, the newly developed spreading vanes of the ZA-V provide an especially good lateral distribution.

The different spreading vanes can be quickly and simply exchanged with the aid of an interchangeable system. The ideal solution for users with different tramline systems and multiple fertiliser types.

The intelligent agitator

The new mechanical star agitator of the ZA-V is positioned directly above the deep aperture and in this way provides a reliable and consistent fertiliser flow at all application rates. Turning at just 45 rpm, it makes for a fertiliser-protecting operation. When the shutter slides are closed on both sides, the agitator speed is reduced to prevent unnecessary damage to the fertiliser.

SBS – Soft Ballistic System (1) Streubild_ZA_V_150309

SBS – Soft Ballistic System

Mineral fertilisers require particularly gentle treatment to ensure precise distribution and transport out to the crop over the total working width. Fertiliser which has been already damaged by the spreader can no longer be spread evenly. The agitator, shutter slides and spreading discs are all optimally matched in the ZA-V. This protects the fertiliser and ensures that yields are maintained.

Double overlap at up to 36 m working width

  • The spreading system on the ZA-V was developed utilising three-dimensional spread patterns, thereby ensuring perfect lateral distribution. Working widths of up to 36 m can be generated thanks to SBS. The large overlap zones provide the perfect spread pattern.
