New Hydrulic Couplings for 706

Cmore · May 13, 2013

It's just darn near impossible to hook up remote hoses to my '65, 706 gasser. You have to "pound" the hoses in and then pound on the slide deal to get them to fasten up tightly. It only has one set of remotes. Is there a different "female" coupling..(the one on the tractor) that I can switch out to make this an easier job?? What brand?? Thanks, Cmore

Are you trying to hook them up under pressure?

Before you disconnect the implement, engage the transport lock, lower the implement to the ground, or block the implement up, then put the hydraulic lever in the "float" position.

Having the implement hoses under pressure makes them difficult if not impossible to connect.

If you still feel the need to replace, there is nothing special about the couplers. They are standard "Pioneer" type female couplers with a 3/4" O-ring thread. Take one with you to buy replacements.

No, not under pressure...but I'll try again..I eventually get them hooked up, but it's a real pain..I relieve pressure by pressing the hoses to drawbar and letting hytran fluid spray all over...Cmore

Here is how I used to unhook/hook up hydraulic couples be it right or wrong.

To Unhook:
If the implement has a transport lock, engage it or let implement down to rest on the ground, then shut tractor engine off and work remote lever fwd/rev until all pressure is off the hydraulic lines, then unhook the hydraulic couplers.

To hook up:
Again turn tractor off and work remote lever fwd/rev to release pressure on hydraulic lines then connect hydraulic couplers.

I don"t know if this method will work on closed center hydraulic system but works on open center system.

Luckily the 706 has an open center hydraulic system.

Cmore, if you have to spray fluid all over, then you are trying to hook them up under pressure. A few extra seconds relieving pressure before you unhook will save you tons of time hooking back up.

I learned right quick the first time I unhooked the disk in the field to go get fuel without floating the hydraulics first. Dad was not a happy camper when I couldn't get hooked back up, and cussed me out pretty good.

The 706 has a "float" position for the hydraulics, one notch past "down" with the lever all the way forward... So you don't have to shut the tractor off if you don't want to.

they are under pressure if you have to relieve pressure by pressing down and spraying hytran everywhere
either get used to hooking up like the guys say or get

Only other thing you have to take into consideration is if you have a double acting check valve on that tractor. It may have. Easy to find out if you don't know what to look for. With implement raised, shut off engine. If you cannot lower the implement it has check valve. If it does, you need to convert to iso male and female couplings that can be hooked up under pressure. The check valves intent is to keep load from drifting down as all spool valves leak some even new and get worse as they get older.

does yours have the ih couplers with the lever to activate them or some other type.

I'm sure IH is 7/8 inch o-ring boss thread.

You are probably correct. I'm just going off the top of my head.
