Fertilizer app- calibration

[Greenkeepers]

Hello all-<p>This is my first post in a while, you guys have been keeping this forum great!! My question is what letter do you guys set your lesco fertilizer (rotary) on for 4lb, 5lb or 8lb per thousand. I'm using Lesco fertilizer and the bag says #15 for 4lb, 17 for 5 lb and 20 for 8lb. My problem is that I don't have numbers I have letters. This is the first year with the spreader and I don't have a book for it either. Thanks in advance..<p>Mike <br>Greenkeepers Lawn & Landscape

Mike- Lesco uses a plastic guage that you insert in one of the spreader holes to set the flow rate. It's supposed to be more accurate than going by the letters, due to wearing of the speader. Any Lesco dealer should have one for a couple of bucks.
