Who uses dual tilt cylinders? I do...

[ovrszd]

Brian,
ZI use the adjustable link on the left side and the fixed link is in storage. I also have the cylinder locked in place , so the slot does not cause problems. I could use a more tilt on occasions, however accomplished.

I agree. I'd also say if that need has NEVER been seen then the user has not used their system in a wide variety of situations.

For me it is ergonomics, much easier to turn around to the right to control the levers and see the implement. If the levers were on the left side it would be the reverse.

Yep, me too. An example would be running the right hand controls while looking over your left shoulder. Sometimes it's unavoidable. Always uncomfortable.

You would need rephrasing cylinders and plumbing to use one valve on two cylinders since the rod end displaces less oil.

I respectfully disagree because the cylinders are not plumbed in series but rather in parallel by way of the T in both fluid lines connected to the directional valve. Actuating the valve causes one cylinder to extend and other to retract. I could, of course, be missing something in the thought process.

One cylinder will have the rod side filling up while the other would have the end of the cylinder which has more volume. I think that's what he was getting at.

One side's pushing up while the other is pushing down (or maybe the implement is pulling at that point). Unless you ended up with a cavitation issue, I don't see why this would be a bad arrangement? Maybe the better method would be to have them spooled separately, but ganged together and 180 out of phase?

That's how I see it too. When one side of each piston is pressurized, the other side of each piston is vented to the reservoir.

No one has shown or even described to me where the 2 hydraulic side links accomplish anything more than a properly built single hydraulic side link will accomplish.

Here is one: No need to get off the tractor and spend time manually adjusting the non-hydraulic side link to get maximum tilt on one side or the other.

A second, although I don't remember if it has ever been useful to me, is the ability to have the lift arms level at two positions, when the hydraulic cylinders are fully extended and when they are fully retracted.

If you don't mind jumping off the tractor to adjust the mechanical side link, then there is no advantage to having dual tilt cylinders... Would I change to a single tilt cylinder? No, but that is just me... IF I bought a new tractor would I put dual tilt cylinders on it? Yes, but that is just me...

What do you gain with all the tilt that the cylinder gets you? It's not like you can actually put an implement in the ground 2' deep and make a single pull and have a ditch done? To get a deep ditch, you have to make multiple passes anyway, so what advantage is all the tilt? Please explain in more detail. :confused3:

So if you start out with the implement level and it is perfectly balanced and symmetrical. You try to tilt it to one side, one side needs to lower and one side needs to raise. The side being lowered will suck in fluid with little resistance while the other side needs to be pressured up to raise. What happens next?

After a few tries making small adjustments everything will be out of whack.

Brian,
I agree that you are not going to make a pass with 24 inches of blade stuck in the ground. I also agree that most times you need to make successive passes to obtain the angle you want.

There are advantages to having a wider degree of tilt. An example would be when the tractor is leaning the opposite direction. Most of the time that is in close quarters work where you can't pick the easy side of the ditch or swale because something is in the way. If you are in an open area such as a roadway it would not come up.

Steve, I understand what you are saying when working on an opposite slope, but again, the tractor will only cut X amount. Your JD side link has the implement level when fully retracted. How often do you use your side link fully extended and are actually taking advantage of that full amount of tilt angle?
