I'm stumped as to what it might be, but I don't think Bush Hog. I believe Bush Hogs have the year as part of the serial Number as in 161234 for a 2016 manufacture date. My first rotary cutter 45 years ago was something called an IMCO. When I asked about it the salesman said anyone in Alabama with a welding shop was churning them out left and right. I gave it to a handy neighbor who still keeps it running.
From memory (it is on a different property so I cannot go out and look) my IMCOs diagonal supports are different. But it does look similar.
