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.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o ... [Read Article]
