Can anyone identify this rotary cutter?

[Armentrout]

Has anyone ever seen a mower like this? It was my dad's and I cannot find any documentation in his papers. It's 6 ft wide, gearbox has "Auburn Gear USA" stamped on back and appears to have layers of yellow, red and gray paint. Did not have a stump jumper and both arms that blades attach to have broken. I'm trying to replace blades, etc.

Thanks for any help.

It is very unique with the extra braces to the A-frame.
But I did not see any like it on image searches.

You should be able to take measurements and find parts that will fit the gearbox. Could even add a stump jumper.

Auburn made rotary cutters and was an OEM supplier to Ford and New Holland.
