Gator Mulching Blades that fit a John Deere 42" deck on the LX200, GT200 and GX300 series of tractors. Gator Blades feature teeth on the back side of the blade. These teeth do not cut the grass a second time, they redirect the airflow under the deck to bring the grass clippings back towards the center of the blade to be cut again. This results in shorter clippings and less windrowing (Piling up of grass) as it comes out of the deck. Another nice feature about the Gator blades is they have less vacuum that regular mower blades. This will allow you to mow over some rocks and sticks without picking them up and launching them as far as the regular blades do. Can use as a substitution for OEM blades M148613 and M139976 This blade set will fit the following models with 42" decks:
