Nice site you have here.
I have a 16" moldboard plow that attaches (Allis Style) to my WD-45 but it has been modified. It is now a 3 bottom but looking at the torch marks it was once a 4 bottom. (maybe more?) Is there any way to tell how it was originally by Sr.No. and if so where would I look for that number? Maybe they weren't even numbered, I just don't know so I'm turning to the experts. Thanks, SandburRanch |

| No serial numbers on plows until the last. You can tell by how moldboards are attached to the frame. Are the standards striaight up and down or do the angle to the front? If they are straight up and down its a 50 series plow. If they are angle forward its a 60 or 70 series plow. The coulter standard on a 60 series plow angle to the front, the coulter standard on a 70 series plow are straight up and down. Figuring what moldboard you have is also interesting as different model number of moldboards were used on every series of plow. this is kinka a quick a dirty ID method, so there is lotsa deviations not mentioned here.

Show us a picture. Some other details are that the 70 frame is adjustable width, the 80 is adjustable width and spring trip shanks. Moldboards were sold separately from the frames and are in a different book. A part number from frog, share, moldboard, shin, or maybe landside will identify the bottom for sure. A picture from the bottom (e.g. plow on its left side) can be crossed to the bottoms book too. Gerald J. |

According to the quick dirty method it looks as if it is a 60 series. Does this mean it was a 4 bottom originally? Sorry about the after dark pic quality.
Thanks, Sandburranch

60s were made from 1 to at least 5 bottoms. So were 70s and 80s. The bolts in the cross member show its NOT a 60, but a 70 where the width of the frame can be changed. Now I see in my plow frame book that 70s could be had with a spring trip option too. Its unfortunate it was cut down with a torch, the frames are built like an erector set and it would have been a nicer conversion to have just taken out the third bottom and move the rear bottom forward and to the right. But the blue wrench worked faster on the frame than on all those bolts, I suppose. If it was a 4 bottom, it would have been a model 74 and there were two versions one could be 12 or 14 the other 14 or 16" cut. Measure from the center of the plow beams going crosswise to find what its set for now. Looks like its narrow so 12 or 14" Gerald J. |

Thanks Gerald J.
So it's a 70 series. The beams measure 16"OC. In fact one measures closer to 161/2. That really is a shame it was cut. |

| Was most likely a 4 bttm with a "crazy wheel" on the back although there were plenty of fully mounted 4's after the D17's were in production. |

That plow was set up as a semi-mounted. The long spring under the long depth adjustment held the SC tongue up when plow was not attached, was at least a 4 bottom with the a structural stiffener and that vintage had the crazy wheel in the rear and not a very good plow unless you went straight across the field, very poor performance with contour work, turning at the ends was rough on the tail wheel. We had one behind a D17 for less than 1/2 the plowing season. A fully mounted with 4 or more bottoms will leave you hanging if you are trying to cross a common ditch crossing that can be crossed with a pickup. A later semi-mount with rear steering transport wheel was far superior when plowing and transporting. ------------- |
