Every spreader is a little different. They are typically plastic devices that are not finely tuned equipment. Here is an easy way to calibrate your spreader for proper applications:
- Set it to 1/3rd open.
- Measure out enough product for a small section of your lawn, about 1,000 sq ft.
- To apply the product and see how it does (adjust up or down from there)
You should only have to do this one time and you will have it dialed in pretty easily.
