JD 60 Powertrol Operation

I use a sickle bar mower on my 45 B with remote cylinder. The rockshaft also operates at the same time. I haven't changed anything on the configuration since I bought the tractor 12 years ago. It has 1 hydraulic quick connect on the back of the PowrTrol.

Ole John T is right that the system was designed to run one or the other.

However..... .there is a way to make it work but it would require some modification.

Method 1 would be to install an after market "Baker" valve, which fits between the P-trol box and the rear housing and gives you an extra lever and ports. You could use one lever to operate the rockshaft, and the Baker valve lever to operate the remote cylinder.

Method 2 would be to cut-in to the hydraulic pressure and return lines that run between the governor mounted P-trol pump and the P-trol box. Then you could add a standard dual action valve to operate the remote cylinder. JD suggested this for 60's and 70's that were going to be used with roll-over plows.

The "Baker" valve is an easy fix, though they have not been manufactured new for years, so finding one would be a task, though they seem to pop up quite often. Cutting into the lines would be fairly easy, though those lines are no longer made, so there is some consideration to making a modification to parts that are NLA. Could be a bit risky either way. Someday if I come across some extra lines, even junk ones just for the ends, I might make a set with a tee so that I could get side pressure and return if I needed it on my '70'D.

Do a search on the archives here and you'll find a lot of past discussion and illustrations on the subject.

Boy, you got me there! Not sure I've seen that combination before.

First, I should have read your first post a bit more carefully. The F2250 R special fitting is not something I've ever noticed or dealt with. What it appears to be is a port to the remote cylinder AND an open front to supply the rockshaft. You could make these possibly by drilling holes in the fronts of your current cylinder plugs.

Next, It's possible that if you hook your hoses to the side ports and use a AA 5724 R Selector valve that when you move the lever the rockshaft would come up and after that the cylinder would extend. On down command the reverse should happen. This is what think is happening for the fella with the #5 mower. It sounds like he is using a one-way, or single action (one hose) cylinder, which is getting pressure after the rockshaft cylinder has fully raised.

To you statement: If I connected the cylinder hoses to the side ports, AND put a shutoff valve in the supply line to the cylinder, AND put the rockshaft plugs in the back of the powertrol, would this work?...I would say yes I think it would. It would certainly be an easy try to find out. What I see happening is that after the rockshaft raises, the lever will seek to go to neutral, but you'll then want to open the shut-off valve to operate the remote cylinder, so you maight have to re-engage the lever forward after you open the shut-off valve. That would take a lot of hands. That's why I was suggesting an AA 5724 R.

Is that what you're looking for ? What kind of implement are you planning to use?

I have a similar installation on my '70'D with a 45W hydraulic dump loader. Here's how I have it configured.

I use a AA 5724 R selector valve in the top P-trol port. I have hoses to the loader connected to the side ports to quick couplers. When I want to use the thre point, I disconnect the hoses at the quick coupler. My loader will stay up if I disconnect the hoses. Yours may not. If not, you can configure a chain from the frame to the lower arms and chain the loader up while you use the three point, Or I've seen them chained from the top of the pedestal where the two top cultivator studs or bolts would go. I have seen one fellow who placed a piece of heavy pipe or square tubing through the opening just in front of the valve cover, and let the loader rest on that. This will let you use one or the other with out demounting the loader.

Otherwise, I think you would have to go with one of the previous methods I mentioned.

If you want a really slick way to go, find a PTO pump to use for the loader. Since you probably have live PTO, you'll have three point and loader capability simultaneously.
