Front-End Loader New Kubota Loader on my old L345DT

Kevin, Since I'm only seeing this now, this give-and-take may be setting a record for most drawn-out thread !

If your loader valve has a "power-beyond" port - usually marked PB on the valve, you can connect a hose from it to the back port on the block to supply the 3-pt hitch. (exhaust flow from the loader valve still goes to the trans).

Blast from the past on this post! I managed to figure it out to work around the lack of a PB port in my loader valve. It isn't going to win any awards for streamlined design but it worked like a champ all summer so I'll take it! Thanks!

Got an email about the hydraulic block - I'm posting the answer here. Under the seat there is a 4-bolt cap that connects two hydraulic block ports together. There is an available adapter that replaces the cap - it has pipe-thread holes for fittings. One hose powers an aux valve and the other is to bring pressurized oil back from the aux valve's power-beyond port to run the 3-point hitch.

Now is where I brag about Ronnie Bowman at Tractorsmart.com - a VERY helpful guy. I happened to have one of these adapters - but a friend is also putting a loader on a L345 so I wondered if the adapter is still available from Kubota. The original is discontinued but Ronnie kept digging until he found its functional equivalent - part No. 70050-00279 price $88.30. It is the key part for tapping into the internal hydraulics for these early '80s tractors - so it's worth it's weight in gold. So is Ronnie. Great job.

IF YOU EVER DECIDE TO RETURN YOUR HYDRAULICS TO "THE WAY IT WAS" MAKE SURE YOU KEEP THAT "LITTLE BLOCK W/ 4 HOLES SO YOU TO CAN PUT IT BACK........A REPLACEMENT IS $200.00............SOUNDS CRAZY BUT I TURNED MY SHOP INSIDE AND OUT TO FIND THE ORIG. TO CAP THE SYSTEM..........
