Hey guys I just purchased a John Deere model 70. I am trying to hook up a remote cylinder to the power troll unit. It is currently routed on the right side of the unit. I have the hoses connected but am unable to figure out how to operate the cylinder. I have exhausted all ideas, please help any suggestions would be appreciated. Thanks in advance! Travis

Is the pump engaged? I think there is a disconnect for the pump ahead of the starter pedal. The engine has to be
off to engage it. If you have no hydraulics at all, that could be the problem.

I have the pump engaged I assume I still have dummy plugs as when I pull the bottom one oil comes out. I don't understand what the hoses on the side are for. Then if I get new plugs, do I need 2? One for output and one for return....

the 60 we used to have had a set of screw in adaptors that went in on the back of the power troll, you had to let the rock shaft all the way down before taking the plugs out to install the adaptors OR you got a oil bath, they had a 2" or so pipe that went into the power troll unit, then the rockshaft did not function but the remote hoses had power
cnt

Make sure the Powr-Trol pump shift lever is turned ON.

It is located just Rabove the flywheel cover on the left side of the tractor.

The tractor must NOT be running and must be shut down in order to turn the pump ON.





Make sure the Powr-Trol is full of oil.

Open the Powr-Trol oil level cock and look for oil to drip out.





If the Powr-Trol needs oil, then add oil at the Powr-Trol filler plug.





Since your Powr-Trol is "currently routed on the right side of the unit", then make sure it has two AA4981R plugs (dummy) installed.



Make sure the hydraulic couplers are good.



If the remote cylinder has one hose, then use the bottom hydraulic coupler.



If the remote cylinder has two hoses, then you might consider using the bottom hydraulic coupler for the supply hose and the top hydraulic coupler for the return hose.

Hope this helps.

James thanks! I believe both plugs are dummies. I have the pump on but get nothing back at my hoses. I'm not sure if I am perhaps not operating it right. If I pull the bottom plug it does leak oil

Take a look at the diagram below.





Note the lever (Key 57) that raises and lowers the rockshaft.

With the Powr-Trol "currently routed on the right side of the unit":

Moving the lever forward will raise the rockshaft arms and then supply oil to the remote cylinder.

Moving the lever backward will return oil from the remote cylinder and then lower the rockshaft arms.

Hope this helps.

Not that familuar with a 70 but I think it should be about like the A & B systems. You could go in the back to plug in the hoses or go in from the side. If you went in from the side you used the dummy plug ib the top outlet but there was a valve that went in the bottom place that you took a cap off to get to valve to change from rockshaft to remote, If you did not know about that valve you would thing it was just a second dummy plug but if you look very close you can see where the cap unscrews to get into where the adjustment knob is and you turn it in or out 2 rounds to change from rockshaft to remote. With set corectly for remote you put the lever in position to drop, on the number series that is back and the lever will stay there, is that valve is not set corectly you have to hold the lever all the while for cylinder to go to drop, it will lick back to netral any time you let go of the lever. I think you are confusing the dummy plug with the valve that replaces the dummy plug if hoses are connected to side, The dummy plugs are used to block the outlet to the rear, noy you canuse a set of hose adapters and hook up the cylinder to the back but if you do that and there is a breakaway in where those plugs go if you pull the hoses out like say a plow that trips so it does not break the hoses you will get a heavy bath of hydrolic oil. that is why things are usually hooked to side and a set of external breakaway couplers used so you do not loose all the oil and get that oil bath.
