205 gyramor rotary blades

[Cleared4approach]

I have a question about a part number for a JD 205 gyramor rotary cutter. I recently picked one up and i wanted to swap out the blades because the current ones seem really dull even though they do cut. On JDPARTS it has part number W39207 and when you do a basic google search for blades for a 205 rotary cutter the part number shows up as W34286. So I am not sure what part number is correct.

W34286 when entered into JDparts cart subs to W39207. Take note of the A&I part number(A-W34286 ) in my photo. Have you considered sharpening the dull blades with a hand grinder?

Yes I did think of it but the blade is more rounded and pointy on the end so not kuch of an edge on it, but i also dont know how long the blade was on for and if I would be able to get the nut off, would it be eaiser to take off the arm that holdes the blades or use a wrench to take them off but dont know how to stop the arm from swinging, aso one of the blades does not rotate freely it is stuck in place.
