I am an new owner of a PG Magnum. I love the machine and up to this point I've had great results until I got a dreaded phone call from a customer who claimed he had streaks in his yard. I went to do the service call and he was definitely correct. Perfect lines, spaced perfectly apart, dark green. This property sits on a cul de sac, on a hill, and is about 2.5 acres. None of my other customers have any problems like this. The only difference is that I used Lesco 32-0-10 70% slow release on the lawn, as opposed to 32-3-8 30% SR on my other customers properties. Did I just have a mind meltdown and not open the third hole, or what? Any suggestions to "fix" the problem? Any fellow Magnum owners out there have any quirks with there machine?
