| 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.
