We would hate for you to pay a restocking fee - here is how to correctly measure your head so you order the correct part.

Older models use a 2.625" cutting circle and newer models use a 63mm (2.480") cutting circle (Cutting circle = diameter of cutter head including knives). To determine what cutting circle your cutter head uses, please do the following:

  • STEP One: Wrap a piece of paper around the cutter head so that it is just touching the knives (keep as true a circle as possible). Put a mark where the edge of the paper wraps around and meets the body of the sheet of paper.
  • STEP Two: Measure the distance between the mark and the end of your paper.
      • If your measurement is 8" to 8 1/4" long then your cutting circle is 2.625" in diameter:  Order the G6 Model Head.
      • If your measurement is 7 7/8" or less, then your cutting circle is 63mm (2.480") in diameter:  Order the G-6/63 head.

When you place your order, please select from the drop down menu above to order the correct model for your application.
