ZA-TS mounted spreader

No calibration. Top up the spreader hopper up and off we go! There is nothing simpler.

The weighing system offers controlled convenience and more reliability. It enables on-line determination of the different spreading material properties with two 200 Hz load cells – providing a high level of measuring accuracy. It automatically compares the actually applied rate with the pre-determined rate. Deviations in the flow characteristics, for example when spreading blended mineral fertilisers, are detected and the spreader is re-adjusted automatically via the electric metering shutter slides. In addition, the applied rate is accurately documented for field-related nutrient application. In addition, the application rate can be altered at any time by pressing a button on the ISOBUS terminal.

On the Profis system, any possible effects of gravity on the measuring of the hopper contents are taken into account during work with the help of a tilt sensor: A twin-axis tilt sensor that assesses the front and back tilt as well as to the left and right, corrects measurement errors that may arise when going up and down hills or when driving across a hillside.

The advantages
Regulating/calibrating under all operating conditions: 

• Side, border and water course spreading 
• Part-width section control 
• Using application maps/N-sensors 
• Spreading of blended fertilisers

Accurate weight measurement: 

• display of residual volume 
• Residual area and residual hopper level display 
• Documentation of the total volume spread

For the ZA-TS Profis with tilt sensor, the angle of the spreader is conveniently displayed on the ISOBUS terminal via spirit level symbols for simplifying the horizontal alignment of the ZA-TS.

Profis – Intelligent weighing system
With the frame-integrated Profis weighing system, the hopper and its frame are connected to a separate chassis via two 200 Hz weigh cells on the ZA-TS or via four weigh cells with the ZG-TS. Thus, there are no weight measuring points which are influenced by the traction forces of the tractor. Precise online weighing every 25 kg is the result! An additional tilt sensor is fitted to compensate for the inclination of the machine on slopes. In the case of the ZG-TS, the signal is also used to counter-steer on slopes via the steering axle to prevent the ZG-TS from drifting downhill.

FlowControl – torque measuring system
The FlowControl torque measuring system reliably monitors the torque on each spreading disc drive from the very first second and can adjust the position of each spread rate shutter in the event of a deviation from the target rate irrespective of the side. The applied rate is precisely documented for a field-related nutrient balance. In addition, the application rate can be altered at any time by pressing a button on the ISOBUS terminal.

The benefits

• Absolute precision from the very first second 
• Side-independent calibration of the application rate in any field situation 
• Highest precision through simultaneous monitoring of the weighing system and the torque measurement 
• Detection of running empty and any blockages 
• Accurate weight recognition with indication of the quantity remaining and the remaining area 
• Documentation of the total amount applied 
• Additional features for ZG-TS: control of the steering axle on hilly terrain and load-dependent braking force control
