Hi,

I have a 4 bottom 2000 series plow.

I've read that these plows used different bottoms over the years with many no longer having parts available. What's the easiest way to identify what I have? I can add a picture later today if that would help?

You MUST first remove a few parts to find the part numbers on the backs. Then you can identify which bottom you have. Even with a picture, one can only guess, then it is still easy to be wrong.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

After studying plows and bottoms (as reflected in AC Plows 101 over in the knowledge forum), I believe that AC offered many bottoms all the time and they use the same mounting hole pattern so that the same plow frame shanks fit every plow bottom. And that when ordering a plow the farmer ordered the plow bottoms separately.

The plows were offered with different shaped moldboards to handle dry or sticky soils differently and then shares were offered in several sizes (narrow cut, full cut, deep suck) and materials (chilled iron for the best wear in the absence of rocks, hard steel for good wear but a slightly better tolerance of rocks than chilled iron, and soft center steel what wears the poorest but tolerated hitting rocks the best.

In recent years the 375 bottoms have been most popular with alternative makers of plow bottoms. My 2000 has 392 bottoms and 15 years ago or so I was able to get needed shins from a Texas AC dealer and to identify the parts at a Marshalltown IA dealer who had a later plow bottoms book than I now have.

Yes on back of moldboards, shines and plow shares. If you find numbers on backs of any of them. Look them up in parts book. If you don't have parts book post them and we can look for you

Also frogs have part numbers too, and frogs tend to be unique to a particular bottom. Landsides were almost universal, the same part numbers used on most all bottoms.
