Leesburg, Ohio | Can't give you all the numbers, but here's some of them: 7200 series was just after the 7000's. Somewhat heavier, and the 12 row front fold models flexed in the middle, whereas the 7000's were rigid...they introduced the single-disc fertilizer coulters (worked very well) for liquid or dry...I think heavier down pressure springs?? and easier adjustment on closing wheel pressure.
The 1700's were next. We still have a 1760 wing-fold...not as heavy-built as the 7200 front-fold...the 1780 would be the replacement for the 7200 front-fold. Just after this series was introduced, Deere came out with the newer style Max-emerge units...black plastic inserts on gauge wheels, heavier parallel arms, cast closing wheel brackets (broke every one of the originals...they made heavier replacements). 1780's were available in 15" spacing, I think.
You don't say what size...I wouldn't be afraid of about any 6 row model, although I would prefer the "conservation" model 7000 or 7200...I think they had heavier wheel frames, but the trade-off there might be the more complicated hydraulics.
For a 12 or 16 row, I would go for a 7200. The electro-hydraulic systems seemed to give more trouble on the 7000 series. Thats why I like the simplicity of the 1760 wing-fold...no "electro", just hydro.
Some plate type 7000's are out there...wouldn't want one. Have had finger pickup meters and vac meters. Happy with both/either. Didn't particularly like the spacing of the old bean cup meters...I think newer style bean meters are much better. We use 750 and 1560 drills, so why am I complaining...they say they are just controlled spills.
Someone else will have to jump in for the newer models.
Hope this helps...
