Asymetric 3-pt hitch plumbing on a 47 H

I"m getting back to plumbing a three-point hitch I"ve assembled from gathered parts. It looks like a well-made homebuilt done pretty close to the Saginaw design. I"m planning to run a hose from the left (clutch) side high-pressure outlet from the belly pump - back to a T at the rear edge of the deck. After that I thought I could run a pipe to get the right side of the deck and then I"d run a hose from there to the right cylinder and a hose from the left side of the T to the left cylinder. This would make my pipe-hose setup asymetrical but my intuitive, naive grasp of hydraulics tells me this would not make a difference since the volume I"ll be displacing on either side will be equal. The pictures I"ve seen of the saginaw setups have had symetrical plumbing schemes with the T happening just above the middle of the hitch. Will the first setup I proposed above work O.K.? Thanks for your time.

As mentioned below, it makes no practical difference in your application. In fact, if you were using IH fast hitch cylinders, you could plumb directly to one cylinder and use the extra ports in the first cylinder to connect the other cylinder. You save the cost of at least four fittings (2 swivels and 2 T's) and probably some hose.

Somewhere in my long lost past, I recall seeing hydraulic brakes set up like that. It does simplify things.

On the other hand, diesel fuel injection lines have to be equal in length so that each injector pops off at the same pressure (which means the same time before TDC). The steel lines actually expand and collapse with each fuel delivery.

jim is right on.

Being asymetrical has NO effect on the system. Think about it, the lines are full of hydraulic fluid. Once pressure is applied, the force is instantly applied to both sides. There is a very very very very very slight delay in the side furthest from the T fitting, as the energy has a finite speed through oil, but the pressure normalizes almost instantly. These numbers are so miniscule, so much so, that they are not worth mentioning, but I did anyways =P.
In other words (in Jim's words) Go For IT!!!

No problem, Hydraulic pressure is applied equally in the lowish pressure modest volume system you are working with. Go for it. JimN
