Cutting Blades - Yardman Woodchipper

yorkie, what does the manual say?

Cannot find it? Well, you can get one here.

You will need the model number, AND the serial number. Enter them in the appropriate space and the proper manual will come up.

Happy chipping!

I have a 1985 Yardman 10HP chipper. On mine, there is a drop down plate under the blades (bottom of machine that faces the ground under the actual chipper compartment) that can be unbolted.

If yours is the same or similar:

1. Remove the spark plug wire and ground it securely.

2. Remove the plate.

3. Using a Milwaukee right angle hand grinder or similar grinder, sharpen the blades following the original contour of the blade.

4. To rotate the blade easier (to access each blade head), remove the spark plug.

In any event, you should be able to access at least small areas of the blade(s) at a time without breaking down the entire machine (hopefully).

Hope this helps.
