I purchased a new Super Z 2566 last November and I've mowed twice with it so far. Yesterday I thought I'd test the speed a bit, probably mowing around 7-8 mph. I noticed that I had a straggler here and there between the left and middle blades. If I slowed down, to around my normal 5 mph the cut was perfect. After reading several posts, I found one that discussed this issue the Hustler's fix for this. This first picture shows a picture of how my deck is currently configured. Supposedly there is a fix for this as picture 2 and 3 shows. Basically rear free-flow triangles bolted into place. My questions are: 1.) What is the part number for this fix? 2.) Does it correct the issue? I am very pleased with the Super Z. It's cut my mowing from 7 hours to 2 hours and 45 minutes and even with a straggler here and there, it's still the best cut I've ever experienced. Just looking for a proven solution to the straggler issue in northern grasses. Thanks!
