DE | depth increments on 1560/90 is 1/4" compared to 7/16" on 750. 1560/90 have two lift cylinders, one for each rank, to follow ground contour better and maintain proper down pressure. Some late 750's may have two, I think. 1560/90 have better bearings all over. The 90 boot will fit right on to the 1560 with no modifications. They both use same opener minus the two grease fittings for the press wheel and closing wheel arms that the 90 has now. I have 1560 and drilled holes and installed grease zerks on the arms and installed 90 boots. I now have a 1590 as far as I'm concerned.
