I removed the blade on my Troy-Bilt and the wave washer and another thicker washer fell out while I was not looking.
Model 12AE449D011
250539
Serial # 1F048K10393

I am not sure which goes first because the manual don't show it. Wave washer , thick washer and blade adapter ? or thick washer, wave washer and blade adapter. The manual said to pay attention to how it came out. It fell after I walked away and I had not read the manual first.
I hope the blade is not like everything else, back ordered .
What year would this mower be if you can tell by the numbers I posted ? Thanks
