Part A: Choosing a Machine

Key Considerations

• Bout Width:
  • Check ease and cost of adjustment.
  • Ensure compatibility with tramline widths; some have max width limits of 12m.
• Accuracy:
  • Machine must achieve recommended application rates with precision.
• Spread Pattern:
  • Ensure even overlap and distribution.
• Headland Spreading:
  • Check mechanisms for effectiveness; may require additional purchases.
• Construction and Hopper Capacity:
  • Inspect for durability and sufficient capacity.

Calibration

• Essential for each fertiliser type to ensure even application.
• Use a rate calibration kit.
• Consider working height for compatibility with tractors.

Part B: Servicing and Maintaining the Machine

Maintenance Tips

• Daily:
  • Wash after use; do not leave fertiliser in overnight.
  • Check bout width, rate setting, and parts for wear.
  • Replace worn parts with manufacturer's recommended ones.
  • Use electronic tachometer to check spinner speed.

Safety Precautions

• Clean all material before maintenance involving hot work.
• Do not weld or hammer precision parts like vanes and discs.

Spread Pattern Testing

• Tray tests are essential to ensure correct spread patterns.
• Adjustments may be needed based on test results.

Part C: Using the Machine

Safety Guidelines

• Ensure all safety guards are in place.
• Never make machine adjustments with tractor running.
• Avoid pushing damp fertiliser through agitators.

Operational Tips

• Check spread pattern regularly, especially with new fertiliser types or after servicing.
• Ensure working height is set considering crop height and terrain.
• Be cautious on headlands to prevent over-application or environmental damage.

Tray Testing

• Use full set of calibrated trays covering the full width.
• Avoid spreading in windy conditions.

These notes provide an overview of the key points in selecting, maintaining, and using a fertiliser spreader effectively, ensuring accurate application and machine longevity.
