RCK48-18BX Gator Blades?

[DBT]

I could not find anywhere offering the Gator Blades for the RCK48-18BX deck for my BX1850.

Has anyone purchased a set of these for their 48" deck or found another blade with improved cutting performance over the OEM blade?

I love this tractor, but my old Cub 3205 produced a much nicer cut.

Any input is appreciated.
