A Note on Blade Types
The MAG-9000 grinds flat blades using a 1" wide wheel and a flat table to rest the blade on during grinding. A flat blade has no bends or twists, the edge being ground is flat or straight.
The MAG-8000 has two blade supports and two different grinding wheels included. A flat support and 1" wide wheel for flat blades, and special rounded blade support and a 1/2" wide wheel for mulching blades. Mulching blades vary in design, some have many twists and bends where others are mostly straight with small bends.
The 9000 is only for straight blades. The 8000 is equipped to grind all rotary blades.
