Abstract: A sharpening device for sharpening and grinding mower blades. The sharpening device includes a roller table and a plurality of mower blade mounting platforms that slide back and forth atop a base. The mower blade mounting platforms include an electromagnet that secures a mower blade to a support surface and guides for directing the position of the secured mower blade. The sharpening device further includes a plurality of sharpening members, such as grindstones, that engage with the mower blades secured to the mower blade mounting platforms. Each mower blade mounting platform includes adjustment mechanisms that allow a user to alter the lateral position of the blade and the sharpening angle of the blade. A first and second motor causes the mower blade mounting platforms to reciprocate and the sharpening members to rotate.
