Clymer, NY | What are the differences between con. and std. I see some planters for sale that are listed as notill or say conservation on them but don't look they have the different lift wheel set up or can't see the frame in pictures. I'm wondering if they are other ways to tell if it is actually a conservation planter |

Northwest Ohio | I think that the conservation planter have a hydraulic cylinder on each marker whereas the std use the cable system hidden inside the main frame also the conservation frames are 7x7 vs 5x7 on a standard version at least this is true on 7200 series and up. Someone will correct me I'm sure if this is wrong. |

East central Nebraska | Also each lift wheel has it's own hydraulic cylinder (all 4 plumbed together). |

Central-ish KY | I believe a 7000 has 2040 type gears and the conservation are 40. Both use a 2040 chain so they are essential the same. It's easier to change row width on a conservation than a older 7000. A wide 7000 has to be cut and weld to make it narrow. On the earlier 7000 units, you can't add a no-til coulter or row cleaner. Later 7000's and convervations, you can. |

| The older 7000 use 2040, the later ones used 40 in the transmission. Both chain and sprockets. 40 gives the possibility of more planting rates but may take custom or extra sprockets to get there.
I had no problem adding trash whippers to my 1974 7000 which is fairly early. They bolted directly to the front of the row units. It was a 4 row wide with the two wheel wheel frame. I had to cut the wheel frame and weld to narrow it. The row units moved easily.
Conservation planters with the bigger main beam, I think, don't use the wheel frame, but use individual wheels and cylinders bolted to the boom just like the row units and planters larger than 6 row, so are much easier to change width. I don't know that conservation 7000 use a different transmission chain and sprocket, I suspect that option is later so would use 40 instead of the earlier 2040 like is on my planter.

| Factory no till will probably have a wide waffle coulter on the front of each row unit which I consider a damp ground stomper when it fills with mud. My standard 1974 vintage 7000 plants notill just fine with Dawn Trash Whippers and I put flat plow coulters out front for injection 32% for corn and for cutting corn stover when planting beans.

Statesville, NC | My 7000 has what appear to be single pitch sprockets, but requires double pitch chain. I tried single pitch chain on it and it would not wrap around the 14 tooth sprocket. The double pitch chain worked fine. I discovered the sprockets looked like single pitch, but were machined slightly different for double pitch chain. On the small sprocket, each link bends more, and the distance across two links bent at an angle is less than the distance across one double pitch link. |

| If you are looking to buy one there is one on a small lot near Spencer IN. Mullin Equipment 812-327-0464 cell or 812-650-2520. Just saw this last week on a small road trip, not mine, have no connection to it. |
