I was surfing the exmark section of ebay when I came across a set of Meg-Mos for my Lazer Z. I quickly put a bid in of $150. I ended up winning and shipping was $25..... Total so far $175. When i get them the blades where all very dull and many where no good due to the rounded edges. Seems some one didn't know how to use a hand grinder.... I had to remove the blades in order to sharpen them when I noticed one of the disks badly bent... Now I was heated so i called Meg-mo to see about buying a replacement but was told I should be able to bend the disk back to near perfect flatness so I'll try that tonight. I ordered all new blades and fasteners for about $65 with shipping. This set off ebay cost me more then a new set from Meg-Mo!!!!!! Hopefully I can get the disk back in shape so I won't get even more pissed about it. Moral of the story,.. get your megmos from Meg-Mo. I'll take a few pics before I attempt to straighten the disk out so you can see what I mean by having a bent disk. It appears the person hit a rock or curb hard while going fast which obviously made the blade go back but the forward movement of the mower must of bent the disk upward.
