Hi Guys.
I'm in Wales, west side of the UK.
I have an ST30 with front loader which I've had for about 3 years.
I had a hose start leaking yesterday and it appears to be the return on the power beyond circuit.
I've read a little to identify it to find a part number but had no luck, even from my Kubota dealer.
The hose runs from under the seat to the rear and I've accessed it by removing the right hand rear wheel (from rear of tractor) and a metal panel.
The hose has a straight connector on one end and a 90 degree on the other with blue tape on both ends.
I believe it's the PB hose?
Does anyone know the part number or is it a case of getting one made up?
I've attached pictures of the hose and fittings.
Many thanks in advance.
James

SORRY ABOUT REPEAT PICTURES, NOT SURE WHY THAT HAPPENED?
Fixed it:

For the hydaulic hose find a local hydralic shop to make you a new hose.
That's not a Kubota hose as most of the loaders and plumbing for the loader in your country were made by a third party.

Just for information, my Kubota dealer found me one, £115 + 20% vat…
Went to a local engineering unit, £25 Cash to make one…
Guess which one I bought 😁

Of course it’s not because it not a Kubota part, it’s a third party add on.
My Kubota dealer was probably going to have one made.
Just curious:
Do you have a model number on the loader?
