    We run the gator blades on our 60" and 72" john deere decks. Since those are similar to a mulching blade would I need to get the 8000? Been using a angle grinder but looking for something that's faster and much more consistant

    Hello IALawnPro2

    Please remember when we refer to a mulching blade as one with curves and bends in the cutting edge. If your blades have a flat underside then you can choose the MAG-9000.

    The MAG-9000 will maintain a consistent 30 degreee angle on your blades, and sharpen a blade in 1-2 minutes.

    See this video for a breakdown of the differences between the two sharpeners.

    What's blade # and manufacturer? You are stating a conflict: "gator" and "mulching" mean DIFFERENT things to us who sharpen all the time.

    A mulching blade's CUTTING edge varies along its edge - it goes UP and DOWN just as hilly terrain does.

    A gator blade has NOTHING to do with the cutting edge - it has upswept "teeth" along the back edge of the blade - - think shark fins. Purpose is the "teeth" can reduce the clippings held aloft.

    Blades can have both "teeth" (gators) and "curves" ANYWHERE in the blade (leading cutting edge, trailing edge, etc.)

    Suffice it to say: Curves" (aka wavy blades) which can mean contours, upswept back edges "wings" etc. are there to provide "loft". Loft is what keeps clippings "airborne" so the spinning blades have multiple times to hit the clippings and reduce their bulk. Dull blades will NOT reduce bulk. Crap clinging to decks (and blades) reduce air flow, slow air speed, and will NOT help reduce bulk.

    Most gator's have a reasonably flat UNDERSIDE. Underside is the bottom of the blade as noted when placed upon a flat surface - and if it curves and goes UP and Down along the edge from center hole to tip, you need the 8000.

    If the bottom (UNDERSIDE) of blade from mounting hole to tip is PERFECTLY flat all the way along the edge from center mounting hole out to the tip - either 8000, or 9000.
