I had purchased a 8 row 7100 planter, but it was one of the very early ones and parts was hard to get. I pushed it aside and kept my eyes peeled and found a newer 7100 that had the updated boxes with radial bean meters and I picked it up last week. Yesterday, i started changing it from 30" to 36" spacing and converting it into a 3 row. I left the transmission mounted in same spot and that will be on the right side so it wont be in the road when I transport it on the trailer. I took both carrier wheels and mounted them between the rows so it will ride smoother, I have to buy a corn meter and I will be able to do Beans, corn, and sunflowers. I figured it would be about 1100 pounds when completed and am fairly confident the 3033R and the 3046R will have no problem carrying it and pulling it. I will build hydraulic markers as soon as I go thru everything and get it field ready. Hoppers and lids are good so i think it will be fairly simple when i get it all straightened out.
