How do you convert from a scotts spreader to a earthway spreader?
There is a conversion matrix on Earthway's site to get the conversion from a Scott's spreader to an Earthway spreader. It is easiest to add 10. For example, Scott's spreader set at 4 should be set at 14 for an Earthway spreader set.
You have a Sears lawn spreader and Scotts fertilizer The directions on the Scotts products are for Scotts spreaders Does anyone know how the aperture settings compare?
The Scotts spreader has a dial on there they call a micrometer. The settings on the dial are tested specifically with their products and their spreader. I'm not sure how they compare as I've never seen the Sears spreader. The Scotts Company's consumer services division keeps a list of many spreader types and can often help with setting the spreader before applying their product. You may want to contact them.
