New Blades A48184 OME 3" wide???

I bought 3 new blades wasn't paying complete attention and the Amazon add 3 pack 16.5" Scag A48184 3" .204 OME also fits Lesco Simplicity etc. The problem as many know is that OME for Freedom Z 48" deck is 16.5 - 2.5 - .204. Has anyone used a 3" wide blade or would it be best not to use. Does anyone know.

Thanks
