I run a Exmark Lazer Z HP 52"/23 kaw and have to mulch due to the fact that I cut all residentials and discharging around beds is unacceptable to my clients. I have a hard time sharpening blades and am looking into a dedicated blade sharpener to replace my angle grinder. My current blades are the Exmark mulching blades and they are difficult to sharpen due to their "curved" blade. Do you think that it is worth changing to gator blades for the sake of the easier to sharpen flat blade? What do you use? I have heard people say that the gators do not cut as well as the Exmark blades but is their enough difference to offset the fact that they are easier to maintain? I know about the Magna Matic 8000 but I am not paying a rediculous $950. Let me know what you think!
