Synchronizing two cylinders

On that loader those cylinders are in a way "attached" to each other. If one starts to move the other has to move because they're both attached to whats moving. Mine weren't, I had no tie rod between my tires, so the tire that was easiest to move (the one where the cylinder was extending) always moved first. Once that cylinder was extended the other would retract.

There is no tie rod on the PT. One cyl pushing one way and the other pushing the other way.

The fluid flow to each cyl is done in the $500 steering valve.

Correct, but because those two cylinders are attached to what is moving they are forced to move at the same time and be synchronized. It has the same effect as a tie rod would have had on my system. My cylinders were controlled through a steering valve like you posted also.

A good way to avoid any conflict with two cyl is to use only one larger cyl to steer, if at all possible.

So you have NO way to connect the two steering knuckles?

Could you reverse one cyl so they are both moving the same amount of fluid?

the easiest way i would think you could do it is run a hose from one port on one cylinder the a port on the other one (like take the line that extracts one cylinder and conect it the the line that retractracts the other cylinder and connect a single valve in the other to ports)

Truck mounted plows are plumbed like this all the time. On my personal plow, my work plow, as well as the plow on the loader and three dump trucks with plows at work. All the articulated loaders that I have ever run do the same thing for steering. If your worried about it, how about two single acting cylinders? When one is extending, it is forcing the retraction of the other. The valve will take care of the flow of fluid.

I could have, but I think it took less time to move one cylinder than it would have to fab up a tie rod of some sort since the system wasn't designed with that in mind. It would have taken some work to get it done. I'll know by tomorrow afternoon how everything will work.

The bad thing about no connection between the two steering wheels is if one gets stuck (as in a rut) the other will move until the pressure needed to move the other one is less than that one. It could mean one wheel moving to the stop before the other moves.
