4 mower blades that are 21" in length, 3" wide, 3/8" holes that are 1-1/4" apart center to center. The 2 outside holes are 2-1/2" apart center to center. 2 of the blades have the 1" splined coupler. The 2 with the splined coupler came from a Ranch King mower and the 2 without the coupler were replacements for the same mower. All are sharp and ready to use. Asking $20.00 cash for the four. Please email, call, or text if interested. I have Verizon " No Signal " so please keep trying.
