the difference in the "6"series ie the 114's cs and 116's cs is the cabs. the dominator cab is basic cab. the cabs on the comandors are a early electronic cab ie electric over hydrolic. the later dom's ie vx's have the later cabs
The main difference is the separation behind the treshing system. The Dominator is a walker combine, the Commandor is a rotary combine. On the Commandors (for example 115CS, 116CS)the same treshing cylinder is installed, but the walkers are replaced with 8 tangential cylinders and 8 separator concaves (CS = Cylinder System)
