THE FEMALE HYDRAULIC HOSE CONNECTORS FOR THE 3RD SCV ARE UNDER SO MUCH PRESSURE THAT I CANNOT CONNECT THE MALE HOSES FOR MY ATTACHMENT. I HAVE PUSH AND PUSH WITH NO LUCK. I HAVE ONLY BEEN ABLE TO CONNECT THEM TWICE SINCE I GOT THE TRACTOR. WHAT DO I NEED TO DO?THANKS IN ADVANCE

John,
I've never had this problem, but I've heard that it's best to use some sort of soft metal (like brass) punch to push in the ball in the fitting. This is supposed to relieve the pressure enough allowing you to make the connection. ....

The other fella is right, you have to release the pressure in the hoses. They make a little screw clamp tool that fits over the hose end and allows you to screw in a knob and dump the pressure under controlled conditions. In any event, BE CAREFUL, hydraulic fluid in the eyes is not a fun thing to experience. Prevention is a better idea, make sure when you park the implemnts involved that they are properly blocked up or locked (as applicable) to prevent the weight of the implement from putting pressure on the hydraulic system. ....

It's best to sit the implement on the ground and work all control valves to relief any line pressure before removing a line. It's also good to keep implements out of the sun. An implement that's been removed on a cool day can be hard to connect if it's been setting in the sun on a hot day. When that happens, I've been able to relieve pressure by wrapping a rag around the male connector and pushing it against the tractor. You will get a squirt of fluid, which can be messy. Once whacking the ball with a plastic hammer wouldn't work and I didn't want to use anything harder. I ended up loosening the fitting. Sometimes working the control valve while trying to seat the quick connect seems to help. My loader quick connects are mounted vertically. Some oil pools in the female connector. I suspect that working the valve allows the oil to be forced into the SCV body. However, the main thing is to relieve the pressure before disconnecting a hose. ....

There are connectors that don't work as well as others for disconnecting. The ideas given before will work for getting you hooked up, do watchout for the oil. In the future when you go to disconnect shut of the tractor and move the lever so there is no pressure on the lines. That should help the situation in the future. It is possible to have a bad connector, if you keep having trouble on just one line I would replace the female body with a new one. ....

As has already been mentioned, you must be extremely careful with hydraulic lines, especially under pressure. The connectors should never require more than gentle pressure to operate, if they do it means there is pressure present. The easiest way to do it is to get the tractor into position, then SHUT IT OFF, then cycle the valve through every position, this will release ALL pressure on the tractor end. The connectors should then slip easily together. Best of luck. ....

Someplace I heard about a type of quick-connect that is easier to connect when there is line pressure. I believe they are expensive. I figure that if I disconnect things properly I don't have much of a problem, and there are better ways to spend money. ....

The Connectors that are easy to connect under pressure are called flat face couplers. You are right they are very expensive about 40.00 for male side and 60.00 for female side. They would eliminate your pressure problems ....
