IN FOUR SIMPLE STEPS
blademeasure_714x311.jpg
STEP 1 Measure the blade diagonally from cutting tip to cutting tip.
STEP 2 Measure the blade at the widest part of the blade.
STEP 3 Measure the center hole.
STEP 4 Measure the center to center distance between the outer holes.
 
FIND YOUR ARBOR HOLE TYPE

5 or 7 Point Star Center holes may be 5 or 7 point star shaped.

 

5-point Star 7-point Star

Square or Rectangular

The MTD built blades on many walk behind lawn mowers have a “bow-tie” hole. In this case the OREGON® replacement blade will have a rectangular center hole which will fit on the bow-tie pattern on the blade adapter.

 

Bow-tie Rectangular Bow‑tie/Rectangular

MTD Blades

The MTD® built blades (Bolens, Cub Cadet, Troy-Bilt, White, Yard Machine and Yardman) may have a 6 point star. OREGON® replacement blades will have a “Y” shaped center hole which will fit exactly on the 6 point star on the blade spindle.

 

6-point Star “Y” center hole 6-point Star
“Y” center hole

The two sizes of the 6 point star.

If your blade spindle has a bolt and lock washer that holds the blade to the machine you would use the 11/16” star or “Y” blade.

If your blade is secured with a large flange nut then you would use the 5/8” star or “Y” blade.
