Achieve precise product application with the Landaco Ground Drive Spreader Calibration Checker. This simple tool allows you to input your target application rate and the actual measured rate from a quick calibration test to see how your spreader is performing.
By comparing your measured results with your target rate, the calculator provides a clear indication of whether your spreader is over-or under-applying product, along with a suggested door height adjustment to help you fine-tune performance. This ensures accurate product delivery, reduced waste, and optimal results in the field.

This tool provides indicative calibration adjustments only and is intended as a guide. Actual application rates can vary significantly due to material characteristics, product flow behaviour, machine condition and operating technique. Always verify performance with a physical catch test or a weighed pass over a known area at working ground speed before commencing or resuming a job. Check your spread pattern and application rate in-field under normal operating conditions. Landaco makes no warranty (express or implied) that the calculated adjustments will achieve a specific outcome and accepts no liability for loss or damage from use of, or reliance on, this tool.
