Actually, the hydraulics on the Essex started out as true hydraulics, meaning they used water drawn from the ambient atmosphere rather than the oils we're accustomed to. They relied on a complex system (think of a diesel intercooler, one of the great unheralded legacies of Essex technology) that compressed air against an osmotic membrane (think fuel cells, yet another legacy . . . ) The concept was called contrafridgemetation. There was a reservoir that was part of the whole setup that held back water from humid days for later use, which was supplemented by waste product from the fuel generation characteristic of the engine, an inert compound, soluble in water when condensed. This last feature was of sufficient capacity to keep the hydraulics working even in the dryest weather.
The capacity was such that the only practical limit was thought to be the number of hydraulic manifolds that could be stacked together without disturbing the center of gravity of the tractor. That perceived limit was soon abandoned as unnecessarily restrictive however when, after Nebraska testing, it was found that the neutral gravitational force that was the core of the Essex system, negated any effect of excessive amounts of brass fittings which might be added added to the system. Unfortunately no records exist to tell whether anyone attempted to use iron fittings, so it is unknown whether the lack of hydraulic resistance resulting in this extraordinary capacity would be more correctly attributed to the anti-gravitational or to the anti-magnetic stengths of the design.
