Lawn Tractor blade sharping

[Louespi]

Does anyone have plans on how to build a good gig or device to easily sharpen 46" lawn tractor blades?

Hi Louespi - welcome to HomemadeTools.net

Here are a couple of ideas:

I just use an angle grinder to sharpen my tractor blades. Then I take the burr off the edges with a file. You can tell if you get your blades really sharp by the sound the blades make when they cut the grass. Really sharp blades sound a certain way going through grass. It is kind of a FFFF sound. I can hear it at any rate.
