My GTH28V48LS had the same issue. I took it back to the dealer and they fixed that and the dreaded parking brake hang up in 24 hours!My YTH18542 is the same way, slightly off center. Unfortunately, the splines on the shaft are so few that no matter how I position it, it's off center in one direction or the other.
considering everything you see assembled that is normally sold in a box at a Lowes (or I'm sure even home depot) store is all built by ONE guy in the store who is only allowed 39 hours per week and sometimes not even that, you'll understand how things that like there just isn't time for when he has to build 50 grills and 20 tractors in an 8 hour shift.Sadly, that's how Husqvarna sent it. All preassembled at the factory, though they should have fixed it at Lowes when uncrating.
