Hi all, This is my first post. I am planning on buying a FasTrak 20/52 and have two questions. First, is the lawn burning issue resolved? I searched the forum and it seems like there is a FasTrak heat shield fix, but I'm not 100% sure of it. Second, I've seen two styles of rear-end trim. One is high and encases the whole motor. The other is low and leaves the motor exposed. What is the difference? Is it 52" vs. 44"? Kohler vs. Honda? 2004 vs. 2005? I would like to guard the whole motor if I have a choice. Thanks for all the help. If it wasn't for this forum, I might be driving something from Lowes or TSC.
