The MAG-8100 Commercial Lawn Mower Blade Sharpener is the lowest cost commercial option in the industry.  This unit is made in the USA and will dial-in to a consistent 30 degree cutting edge angle.  Unlike other sharpeners you can easily maintain that 30 degree cutting edge angle without any complicated adjustment or time consuming tools.  The single crank stays where you adjust it and you simply lower the wheel until it almost touches the worktable - and that will cut a 30 degree angle (+ or - 0.5 degrees) over the life of its 7" diameter grinding wheel.  No other sharpener can promise that.  Our incredibly rigid design gives you a smooth solid grinding experience that makes sharpening mower blades comfortable and easy.  All 8100 and 8200 series sharpeners use the same angle adjustment and bearing block system that we call the "heart" of the machine, all of these highly accurate in-house CNC machined parts provide this tremendous rigidity. The MAG-8100 uses all the same grinding wheels that the MAG-9000 used.

The MAG-8100 platform has two different motor options to choose from.

  • 1/3 HP (ODP) open drip motor (PROS: Less expensive CONS: shorter life motor)
  • 1/2 HP (TEFC) totally enclosed fan-cooled motor. (PROS: longer lasting motor CONS: More expensive)

For long time fans of the MAG-9000 (production from 1989-2022) the MAG-8100 is taking its place in our robust model line-up.

Who is this sharpener for? A user only has straight flat cutting edges and only needs to cut 30 degree angles and needs to stay within a budget but needs a professional sharpening solution.

SAFETY CONSIDERATION: The enclosed nature of our sharpeners keeps sparks in control you won't have an uncontrolled stream of sparks. All Magna-Matic sharpeners have complete a enclosure for the abrasive, all sparks are directed into a large grit guard so sparks are controlled, additionally we offer dust collectors for a clean shop. All Magna-Matic sharpeners grind up the cutting edge for safety so the mower blade is always pushed away rather than sucked into the machine.
