755 Hydraulics

Recently I purchased a 755 with a mid mount mower to replace a 184 International. I started looking for a front end loader and found and installed a 210 loader on the tractor. The loader was as new and included a weight box. Custom mounting brackets were made for the installation. My only thoughts are that I should have bought a tractor/front end loader ten years ago, the 755 gets the mowing done much faster ,and the John Deere deck does almost as good a job as the Woods mower on the 184.

In going over the service manual and lubrication points, I pulled the floor board to lube the main driveshaft and noticed that there are two hydraulic lines under the floor board. Each of the lines have capped fitting.

I am wondering if those capped fittings are for use in adding another hydraulic control valve, and if so, what type of valve would be used. (open center, closed center, etc.)

At this point, I don't have a need for another control valve, but who knows what might turn up in the future.

Any advice or experience would be appreciated.

Those fittings are for connecting independent lift cylinder for the mid mower. You can then use the joystick to lift the mower instead of the three point lever.

Thanks for the reply. The parts diagram makes it clear. Looks like the fittings are in the lines that would be used to raise and lower the front end loader, so their use for something else would not work without a work around.

Thanks again.

Thanks again.

Prior to using the loader, when the independent lift has been installed, the mower deck is simply locked in the full up position using the height control on the center platform. The lines then provide full control to the loader. I agree it would not be possible to use those fittings for something else while leaving the loader connected.

Thanks for the replies.

In doing a little googling, it looks as though the 755 hydraulics have a 'Power Beyond' function available. If the need for a third (or more) hydraulic circuit shows up, that would be the simplest way to go.
