Accurate product application starts with a calibrated spreader. This tool calculates the precise adjustment needed to correct your application rate, whether that is a door height change on a ground drive machine, a flow factor update on a Topcon ISO-VR controller, or a product density correction on a John Deere GreenStar system. Enter your target rate, your actual measured rate, and your spreader settings to get a clear, actionable result.

DISCLAIMER

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.
