How many feet do you need to travel to calibrate your spreader if broadcasting granules in a 10 ft swath?

To calibrate a spreader for broadcasting granules in a 10-foot swath, it's important to understand the relationship between the spread width and the distance needed for calibration. Commonly, a distance of 100 feet is used as a standard calibration length for determining the amount of product spread over a specific width.

In this scenario, where the spread width is 10 feet, the procedure involves determining how many feet to measure based on that width. When calculating the area covered by granules, the general practice is to use the formula:

Distance in feet = (Area to be calibrated) / (Width of swath)

For a swath of 10 feet, the calibration size often suggests a distance of about 87 feet. This is calculated on the basis that a 10-foot width covers 10% of the total area, thus leading to the need for a slightly shorter calibrating distance when compared to a wider swath.

Therefore, traveling 87 feet allows for an accurate assessment of the granules being spread over the 10-foot width, making it the appropriate distance for calibration in this instance. This ensures that the spreader is accurately dispersing the intended amount of product across the desired area.
