The Muck Spreader ‘Application Rate Calculator’ is a powerful tool designed to help operators optimise their muck/manure spreader settings and ensure accurate application rates. Whether you’re applying Cow Manure, Chicken Manure, Compost or lime, this calculator takes the guesswork out of machine calibration and helps you achieve consistent and reliable results in the field.
This tool is designed & calibrated for current generation Bunning machines and can be used with other brands of muck spreaders. For additional assistance with calibration, please Contact Us.
Solve for door height, rear roller RPM, or ground speed based on your target application rate.
Results
Door height results are rounded up to the nearest 1 mm to ensure the target rate is met or slightly exceeded. Always verify with a physical catch test before commencing work.
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.
