hydraulic hoses

[GeneralSnafu]

On my M series Kubota, the connection you show is 3/8 inch, right hand, national pipe thread (3/8 inch NPT). I believe the hose end in your picture is a solid connection, so you will need to remove the other end of the hose first. I found a replacement at a farm supply store.

Thanks for your reply. The connectors seem to have a slight amount of wobble where the fitting enters the mounting block. If you look closely at the first picture, you will see 2 small notches in the ring surrounding the connector in the upper left position. This is typical of all 4 connectors except, they are positioned differently on each one. This leads me to believe they are a retainer of some sort, that is able to rotate freely. Looking at the second picture you can see an assortment of fittings ahead of the block and after. I find it hard to imagine that, they would screw that many parts together to make the transition. Every tractor I've ever seen, the rear remotes were always quick disconnect. Any other comment will be greatly appreciated.

Not sure, but could it be some kind of break-away connection.?.....similar to a QC but separates when the hose is yanked on..??

Def pipe thread hoses......if they don't come loose at the adapter fittings and you need to cut them off, then use a hack-saw or thin cut-off grinder to cut the fittings between the hex on the hose and the alum ferrule.....that will allow you to use a box wrench or socket to grab the remaining nub of the fitting

Those might be the type of QD's that you push in first and then pull quickly.

Spray them down and see if they loosen.

They might also be the kind that just pull away as in fast break as when you forget to disconnect.

What do those hoses actually go to, the loader?

Release the pressure on the hoses, grab the hose close to the fitting then push in and pull back out quickly.

I have never seen those kind of QD's on a loader, always on the back.

I store my kubota outside 24/7 for the last nearly 30 years in temps above 120 degrees. Never changed a hose yet.

The hose appears to have an NPT end screwed into the hydraulic block. A few drops of Kroil and a couple of flare nut wrenches should remove the fitting.

I realize they are mounted on the back, some people have tractors without a joystick and the loader is plumbed into the rear. Not really sure why I even asked him what they went to. lol

Thanks for all of the replies and suggestions. Those hoses are connected to the cylinders for the top link & the tilt for a boxblade. There are several deteriorated strings hanging from the block and the hoses. One of them still has a rubber plug. It's similar to the type used to plug a hydraulic coupler when removing a FEL.

Maybe rusted up and can't breakaway, may need to spray down real good, then try to disconnect

I think you may have hit on it. I loaded them up with Kroil tonight and will see what happens tomorrow. It appears that the collars are within the mounting block where it would be impossible to get ahold of them by hand. I will try the quick push and pull method suggested. If that fails, I suppose I could try pushing on the collar with a screwdriver or the like. I'll let you all know how it goes.

I have been selling hydraulic hose assemblies for over 15 years. There is a shelf life the manufacturer suggests for hose, approximately 7 years. Having crimped ends on a hose and using it when needed is NOT an issue. There is no degradation of the hose if it sits on a shelf while crimped...

Release the pressure on the hoses, grab the hose close to the fitting then push in and pull back out quickly.

Those hoses feed two cylinders that control a Top & Tilt setup, mostly for grading.
