BACKGROUND

Lawnmowers are owned by most individuals who have small yards. However, lawnmower blades require significant maintenance to remain fully functional. Said maintenance involves removing and sharpening the metal blades of the lawnmower. Not only is this process potentially dangerous, but the metal blades themselves are dangerous when spinning as they can impact blunt objects like rocks which can damage the blades and shaft of the lawnmower and decrease the lifespan of the mower. Further, metal blades can easily cut off fingers or toes if said digits come in contact with the blades as they are spinning.

Therefore, there exists a long-felt need in the art for an improved lawnmower blade. There also exists a long-felt need in the art for a lawnmower string line adapter blade device that allows a non-traditional blade type to be used with a lawnmower. Further, there exists a long-felt need in the art for a lawnmower string line adapter blade device that allows a non-traditional blade type to be used with a lawnmower, wherein said blade type does not utilize metal blades. In addition, there exists a long-felt need in the art for a lawnmower string line adapter blade device that allows a non-traditional blade type to be used with a lawnmower, wherein said blade type does not utilize metal blades and said blade type is not prone to damage from hitting rocks or other obstructions while mowing.
