What model is this 2 bottom AC Plow?

The number on the back of the moldboard is 372-16. Trying to find out the right model #. Trying to find another landslide.

   It has a #62 frame with #80 series trip stub beams so it is some what of a combination of parts.

Thanks for the Info. That will help my search for the landslide a lot easier. Just to clarify Gerald, the moldboards were not after market. Maybe the moldboard will help me figure out what the moldel or part # of the trip bottom is. The label on the back of the moldboard is Allis Chalmers. Unfortunately that was the only label on the plow that was ledgible. I will post another picture this weekend some time of the landslide I need. The picture I have takes up more memory allowed on this site so I will have to take a smaller one. I've seen you have lots of experience with Allis Gerald, so hopefully we can figure something out more about my late father's plow.

TramwayGuy, you are right on the lift links. I had them wrong and Jim Lux showed me the write way. I could not figure out why the plow did not lift any higher, when we fixed it, it went a lot higher. Jim also showed me that the links them selves were shoved on the tractor lift arms farther than I thought they were supposed to go. The lift link bolts should not be screwed into the holes on the lift arms of my 50 WD, but you shove them on the lift arms farther and there is kind of grove on the lift arms that the bolt screws into. I also use a safety chain underneath where it goes into the snap coupler, that is in case it would ever come out accidently, it would hopefully hold the plow from coming up on me in the seat.

Thanks TramwayGuy,

you run the lift link on top for laying off a land on the first pass.that way your plow runs level when not in a forrow then flip it over after you lay off a land

That page says the spring trip shanks for the 60 were effective in January 1965. Best I can gather from the drawings the rigid shank of the 60 and 70 use the same bolt holes as the spring trip shank for the 60 and 80 so they could be retrofitted. I haven't looked at plow frame part numbers but I suspect all the plow frames had bent bars in common and I know the hitch parts for three point, pulled behind, and snap coupler are listed separately from the frames so they could be swapped out and had to be specified in the order. Probably they were options on the plow frame specification, e.g. you ordered a #62 plow frame with snap coupler hitch. Then you ordered plow bottoms, and coulters specifying the size of landside with the plow bottom or ordered as separate item. And you had a choice of several forms of coulter that often was not specific to a plow frame, but gave different costs and longevity in the coulter bearings, the pivots, and the blade survival when hitting rocks. Some flexed, some didn't.

Reiterating what I see for plow frame variations. 50 has vertical shanks and fixed width. 60 has angled generally fixed (not spring trip) shanks and fixed width (except for one 10-12). 70 has angled fixed shanks and adjustable width for two sizes of bottoms like 14 and 16". 80 has spring trip shanks and adjustable width. Since the 60 takes less steel, fewer bolts and fewer holes I think it was cheaper than the 70 and 80 and at least these three if not the 50 were built for about the same period. There is a chance that I've not worked out that the bottoms for the 50 could be different from those for the later plows but I think the shank to frog mountings were consistent from 50 through 9000 and then 2000. Two 9/16" holes requiring plow bolts through most of the landsides.

Where plow frames and plows were ordered separately (I suspect that they didn't meet until the delivering dealer's shop), its likely these later spring trip shanks and the various landsides were also selected separately on the order. So ordering a plow probably had at least three entries, the frame, the bottoms, and the landsides, and most bottoms had 6 to 12 choices for the plow shares with different materials and shapes for different plowing conditions.

I don't see it from my parts book but its probable there was a kit of parts for the landside assembles with hardware and braces and another kit for the spring trip shanks whether bought new with the 60 plow frame or bought later and changed inthe field. This parts book does show bolt kits for these assemblies.

Landsides came with lengths from a few inches up to a couple feet. The long ones had to be braced and the only thing to brace to was the back of an extended shape of moldboard.

The differences between a 371, 372, and 373 is the moldboard. My book doesn't say what the different moldboards are like. Probably some are short and some are middle of the road and some are long like used for turning sod and in plowing contests. Some plow bottom sales brochures would explain that but I've not seen any of those. Possibly some farm magazine advertisements would have explained that too.
