GENERAL—A variety of hydraulically operated functions are utilized on the 1720 16 Row machine. The number of tractor SCVs required can vary with base equipment and options ordered. A fully equipped base machine including vacuum meters, markers, fold, and SeedStar™ variable rate drive, 5 SCVs are required or 4 SCVs and Power Beyond. The wings and center section of the machine each have their own vacuum motor, plumbed separately, to provide fine tuning of vacuum level to each. They require two SCVs. Fold, markers, and variable rate drive each require a separate SCV. If only 4 SCVs are available, add Power Beyond and run variable rate drive from that unit. It is possible to use only three SCVs and Power Beyond if both vacuum blowers are plumbed together using one SCV. The ability to fine tune each half of the machine using the tractor SCV flow controls is sacrificed.
