E. Sharpening Mulching (Dual Angle) Blades
1. A mulching blade has different angled edges on each blade side:
2. When sharpening a mulching blade adjust the position of the vise handle to either “Low” or
“High” position based on the angle.

To sharpen a counter clockwise blade the process is the same except you have to work on the bottom
blade instead of the top blade.
1. Attach the blade to the Sharpener Clamp (See VI-A).
2. Attach the grinder to the Guide Arm (See IV-C).
3. Extend the grinder all the way down to the lower part of the blade.
4. Follow the same steps in centering and grinding for Standard blades.
