Five clips and a cable to drop the deck. The cable has a spring clip on the end that makes removal tedious and you have to compress a pulley in order to get some slack. Needle-nose Vise-Grips are your friend in all endeavors.
One 16mm socket to remove the blades and a flat-blade screwdriver and a wire-brush to remove all the caked-up vegetation-gunk that is glommed underneath the deck.
A (futile) trip to Home Depot to discover they didn’t have squat, and then a trip to Tru-Value to find the correct size, shape, and “Made in America” blades — you don’t see that too often anymore these days with steel tools and hardware! And at about only $12 each, cheaper then the non-fitting cheap blades at HD!
The old blades are hacked, but they have enough meat on them for a few more sharpening-cycles on the grinder, and from the new blades I have a pattern to grind-to.
