One way cylinder?

[Tractorcedric]

I have a White 2-105 with two detent valves. A neighbor wants to give me a swing arm IH hay mower. It has a two way ram to swing it from left to right. But the ram that lifts the cutter bar only has one line. Will it work on my tractor with just the one line? How would I get it to stay in a float position? Thanks

To use a one way cylinder on a two way remote is plug the single line into the line that is right next to the float detent and to use the float position to lower it.

Correct me if I am wrong, I don't think a White 105 has a float position.

Most hay mowers the lift cylinder is only responsible for raising or lowering the cutter bar. The floating action of the cutter bar is handled by springs.

A 2-105 has closed center hydraulics. The pump won’t care whether it is dead headed when lowering, it is on standby all the time you are not using the hydraulics anyway. The only thing you should notice using a one way cylinder is the handle detent will not work in lower position, you will have to hold it. Provided your detents work in the first place.

You're only "deadheading" the hydraulics for the moment it takes to lower the cutterbar. Not a problem. Just don't hold the lever in the lower position for hours and you'll be fine. Most every modern mowing machine raises and lowers with a one-way cylinder.

Look at Chris Losey, the Oliver Guy. On YouTube.
He explains the one way deal on our brand of tractors.

Ultimately, if whites have no other recourse but to go over relief in order to lower the implement, I’d sooner buy another hose and just run it as a two-way cylinder. I’d never advocate squealing the relief valve for several seconds at a time as part of normal operation.

The "swing arm hay mower" probably has dedicated/special cylinders that aren't easy to swap out to double-acting units.

The other alternative is to plug in a second hose and connect it to return the oil to the sump.

If it’s really IH it must be a 1490 if it’s a swinging tongue. You’re right , it does indeed have a non- standard header lift cylinder with only one port.

Seems strange to me that they would build something that could only plug into certain tractors without re-plumbing it, unless there really is a way to set up a White for one -way hydraulics.

As I said above, there is no relief valve to squeal in a 2-105. The bigger Oliver and White tractors had closed center pressure compensated pumps. When the system reaches the high pressure limit, the pump destrokes.

Running a single acting cylinder on that system will not have a negative effect.
