Kubota front loader 3rd function adapters for attachments on the front?

[Rutcutter]

What does the Kubota 3rd function kit come with as far as adapters for the attachments..

My tractor came with these on the front,is this correct?

My dealer started to ask me what I wanted. Then cut himself off to say flat face are the industry standard & to let him know if I wanted something different. I went with the flat face (1 male, 1 female to prevent hose reversal). I'm pretty sure he meant standard as in industry standard (skid steers especially) rather than standard for Kubota tractor/loader 3rd functions.

You kind of have 3 options:
Flat face - industry standard & most likely to be comparable, clean with little to no connect & disconnect leakage

Ag style - what you have, hopefully matches what is on the back for compatibility. Usually female, but you have male (no clue if that's standard or not). Leaky when connecting/disconnecting & dirty. My least favorite, but the standard for tractors & the cheapest.

Some kind of connector under pressure fitting - I've thought about swapping to this after fighting with AG & flat face (often need to unscrew a fitting to bleed off pressure if it's warm out when hooking up).

Actually I would think your dealer added the connectors after the install. I just finished adding the 3rd function kit to my tractor and the OEM kit comes with just caps on the loader end. This is so you can add the connector type of your choice. I installed a male and a female at the front because I plug the hoses of the attachment together when i remove it from the tractor.

I honestly don't know if there is a "correct" way to terminate hydraulic hose from a third function install. I had my dealer install the third function(WR Long) for my grapple and the hydraulic hose terminates with male connectors, just like yours. The ends go thru and are held by a stand-off bracket and there are rubber caps to cover the ends when not in use. Obviously, since the dealer installed the grapple - the male & female ends are going to be compatible. Will the male fittings be compatible with any other "front end" implement I might purchase that needs third function abilities........it would seem obvious but unless one actually "made" physical connection there could be incompatibility. However, this would simply mean having new female connectors put on the new implement.

So... I think yours is correct. The bigger concern is trying to determine what size, type & "shape" those two male connectors are so you can get matching female connectors for whatever you want to connect to it. I would start by asking your dealer what type, size, etc, etc those male connectors are..............

Man, I hope I made some sense and you can understand all this C-rap I just laid down..............

I went with flat-faced skid steer style. They're available as "connect under pressure" which as Fallon mentioned above would save some hassle. Flat face couplers are nearly leak-free when disconnecting.

I don't think there is such a thing as "correct" QR fittings. You can use whatever type you like. Most dealers seem to stay with flat face since they are easy to clean and don't spill much oil when connected.

I had a W&R Long 3rd function valve added to my MX5800 and the dealer used flat face couplers. The OEM Kubota valve on my L6060 also uses flat face. I made a set of flat face to ag adapters to work with my older implements.

This is what came on my grapple..

I had the third function set up installed on my B2650 last month and no quick couplers were installed on the end of the hoses since my new grapple was not in yet. The male threaded fittings were just capped. Once the grapple came in I bought a set of couplers so everything matched.

On a side note...I do not like this third function set up on my B12650 as it is activated by solenoids and you cannot "feather" the function to make the action smooth and slow. The function is determined by the speed of the engine/hydraulic pump. I have to throttle the engine down to idle so the grapple does not slam shut. This would not be a problem but when I pick up limbs in our orchard I may open and close the grapple hundreds of times and having to slow the engine down so many times is a lot of extra steps. On my larger Non Kubota tractors I can have the engines running relatively fast and feather the third function as fast or slow as necessary and keep engine speed the same.

Those look like they could be "connect under pressure". If you can predict which side of the circuit retains or builds more residual pressure, but the male connector on that side. For some reason the males work better.

...Ag style - ...Leaky when connecting/disconnecting & dirty...

Glad to learn that it's not just mine leaking... I have a single set of Flat Face connectors, sitting on a shelf, they're nicer than the Ag type. :2cents:
