Is this how you measure a plow? Measures 14".

| Close enough for government work, but plow frame may be easier. |

Measuring that width is a decent first approximation except that AC had wide, normal, and narrow cut plow shares, so that width could be exact, long, or short. They'd suggest a wide share for being sure long rooted crops like alfalfa were always cut. A normal width for most purposes, and a narrow cut for ground that needed to be anchored so it rolled over instead of sliding sideways. If you can find a part number (and its an Allis bottom) on moldboard, share, or frog the plow bottoms book referenced in AC Plows Parts 101 up top will show what size its planned for and so what frame spacing to use.

Ya it will get you within a couple inches, but so will guessing it at 14", LOL  but follow the vertical beam that the bottom is attached to up to the horizontal beam it is bolted to. Then go to next bottom and do same. Some plows this is easiest at the rear, some up front, some in the middle but find a place where you can measure across to the SAME SIDE of both beams with a tape or use the square , not inside to inside or outside to outside but left side to left side or right side to right side.

| Look at the plow frame from the top , measure from one upright beam to the next . That will be your number . Measure left to right "SQUARELY" on your frame, not at a 45 degree angle. |

It's a single bottom trailer plow. I think I understand how to measure from beam to beam. But I seem to be one beam short for that method..... ------------- The mechanic always wins. B91131, WC23065, WD89101, CA29479, B1, Early B10, HB212, 416H |

With the single bottom plow you could set it to cut 12" if needing to cut every root like plowing alfalfa to kill it, or 14" if average dirt that turns over well, or 16" if the sod tended to slide instead of turn over. That cutting width is the distance of the left face of the plow share, moldboard, and landside from the inside face of the tractor tires providing you will be running them in the plow furrow which is the usual plowing position. It will plow in any of those positions and in between those positions for that matter, just will turn over a bit more dirt if set wide, while it will pull harder set wide than set narrow. Depends on the soil as well as the shape of the share and moldboard. If you find part numbers that may identify the bottom width, unfortunately some AC plows used the same moldboard, but different shares for different widths. Gerald J. |
