Putting the deck back on yesterday naturally I serviced it. Scraped it & went to sharpen the 3 blades. Seems to me the blades on it are original & time to order some new blades. So I get the blade number & hit Amazon & now sorta stumped?

I'm leaning toward the high-lift but then the mulchers seem good also?
Don't know?????
What type of blades-- Any suggestion's that you've have with them???????
Nik,
Thank You.
