Thanks, Jim, that helpsJim Becker":13de29vx said:The direct-mounted 2-bottom plows for the C were either 12 or 14-inch. The number 39 plow, which IH called a "roll-over" plow, came either 14 or 16-inch. The 39 was a pretty heavy-duty plow. Whether a C could pull one would probably depend on which size bottoms it has and even more so on what type soil it is in and how deep you were trying to plow.
