Could someone offer up the name of a thread that discusses the issue of a z-spray spreading heavy to the right. My searches came up empty. Here is some background on my issue. This summer I switched to a granular grub control product offered by a company called Prokoz and the product is called Zenith (http://prokoz.net/site_files/products/file/Zenith.pdf). It is a straight Imacloprid product with no fertilizer in it that has a very small prill size that is preventing me from adjusting my Z-Spray pattern to get the product to evenly spread in front of the machine. This product is staying on my spinner plate too long and is being thrown off to the right. After struggling with this adjustment on a couple houses to get it right I stopped to look for suggestions. FYI Z-Spray was helpful over the phone in illustrating how the mechanism works and offered up that to properly adjust it you only need small adjustments to the cable to change the pattern greatly 1/8" at a time. Unfortunately, I could not get this product to properly spread after several attempts at these micro adjustments.
