Options:

1) Try contacting Agway to see what setting they recommend.

2) Return the fertilizer and buy some Scotts fertilizer. It is pretty
reasonably priced in large bags at Sam's Club, Costco, BJ's,
etc.

It is extremely difficult to go wrong with both Scotts fertilizer and
a good Scotts spreader. Don't buy any Scotts fertilizer which has
been manufactured to be sold under some second party's (retailer's)
house label. Those are often inferior non-complex fertilizers similar
to the bargain brands. Much more preferable are the fertilizers which
are uniformly blended before the prilling process, producing those nice
uniform pellets of fertilizer. The multi-sized, multi-colored prills of the
less expensive bags generally do not get spread as uniformly as the
blended prills.

To the best of my knowledge, Scotts standard lines of fertilizers
are always uniformly blended prills. Their secondary market of
house brand fertilizers aren't. When you observe a bag of fertilizer
which has multi-sized prills and/or multi-colored prills, you are
observing a product which was manufactured cheaply.

Scotts appears to have done consider R&D in determining how to
produce fertilizers which spread uniformly, release slowly, and
release uniformly. Which is why they have that famous "no quibble"
guarantee.

Also, Scotts (and their Ortho division) have pretty good toll-free
telephone support and advise. My only complain in that area is
the fact that some customer support folks are obvious not super
astute and are reading from scripts, checking manuals, or doing
computer searches to answer questions for which they have little
knowledge base. That's when I hang up and try another day, hoping
to get one of the more experienced staff who really knows his stuff.

I have no connect with Scotts and I'm not shilling for them. I'm
just passing on my observations and learning experience from decades
of trying various products and ultimately deciding upon Scotts. I got
tired of trying less expensive products which didn't perform well. Or
products for which I had to guess spreader settings.

If you are fertilizing a lawn yourself, then you are saving a tremendous
amount of money versus having a lawn service do the fertilizing. When
you are saving a few hundred dollars, why try to cheap out and save
an extra few bucks buying the bargain products?

Now, if only Scotts could start once again producing a broadleaf weed killer
which works well. I'm no longer pleased with the their weedkillers
under either their Scotts label or their Ortho label.
