Okay this mowing business is part-time for me so I am not going to spend $800 plus for a magna-matic or any other blade sharpener. I got one of those Home Depot $40 grinders to sharpen blades. So have you made any modifications or add-ons to your grinder to sharpen blade better or quicker. Anyone seen a tool/device that you can buy that you adjust to create any angle you want so you can lay the blade on it and then push the blade against the grinder wheel to start sharpening the blade? I would be like if I cut a long triangle piece of wood out of a 4" x 4" and lets say the triangle is at 30 degree angle. Then lay the blade against the 30 degree angle part of the wood and use it as the guide to sharpen the blade at a 30 degree angle.
