Super 77 gasoline,  42.3 belt hp corrected.  Mine dynos close to 100(usually on high side), we pulled a 2 row FOX chopper, 4-16" drag type moldboard plows(IH # 60's), 12 foot tandem disc.  Plows in 3rd and 4th, disc in 5th.  It was used a few time on a 6-36" AC 333 no-til planter, ran it easy.    "Killer" when feeling good is fierce.

By the way that is a 10 inch by 51 foot auger and it is run full. With ease.
