Well, from 1957, that was all we pulled when plowing and in Central Ohio we have it ALL..Black-Jack and Jack Wax included..
Plowed many an acre of mature alfalfa..never fell below 2nd gear... 2 of us with 4 bottoms would leave a good mark in a field 1/2 mile long in a day..(60 acres) Dad'e came with his 45, a 4x14" semi-mounted.. Now, all tires were loaded to the top and a railroad rail chained in front of the radiator.. Dad's was one of the original "demonstrator tractors" and mine had a M&W kit in it..they were nearly a perfect match for power..
