A device constructed of a material strong enough to withstand the torque of a typical air wrench or cheater bar used by a lawn mower repair shop or a homeowner. One end of the device must have an opening and be of the size as to allow a lawn mower blade to be inserted inside of it. The portion containing the tip of the blade may include a leveler and/or retainer to raise the device to approximately the horizontal plane of the mower blade and the lower edge of the mower deck. The device includes a restriction leg to provide a prop against any protuberance on the side of a single-blade mower deck or on the side or within the deck on a multi-blade mower deck. To provide economics for manufacturing, one size should fit most blades and the device should require a limited quantity of materials and fabrication.
