Rotary Cutter Frontier

[St Croix]

Who make the Frontier RC for John Deere?
I need a new set of blades and wonder what manufacturer replaces the JD part number.

The older Frontier mowers were made by Midwest out of Illinois, they are currently out of business, the current versions are made by Tarter Gate from Danville, KY.
