When I got my new turf tiger the blades felt sharp and the dealer said it was all lubed, oiled and ready to cut. I cut a few yards and the cut wasn't that great, leaving stranglers on the left side blade. Not happy since I heard all the good stuff about the TT. Thought I had a lemon. I got home, sharpened the blades and greased the spindles now the cut is awesome. Lesson, never trust anybody about your equipment.
