Mowing Got a 930 Series 48" mower question

[jclaudii]

I am wondering if I can use any 48" mower blades that fit the criteria of what is supposed to be on it? The manual calls for a 16.81" blade length and the blade kit that comes from new holland, prices I found online, seem to be in the $95 dollar range. I would love for it to be about half that

Specs (2 pages)

Here is the part numbers I found:
W0D65116 KIT Kit, Blade, Package (3), 48", Models 22WD5100 & 9606338

Anyone have any knowledge of this mower? It is used as just a general mower around my Moms place...don't need anything pretty, just safe and reliable cutting!

Thanks!
