new to the forum and looking for some advice and guidance...
apologies for the long scene setting!
I'm in the UK and recently purchased a new EK1-261 (a result of the purchase of Escorts by Kubota I believe and the machine is almost identical to the FarmTrac FT26).
The machine comes with an auxiliary rear single DA spool with QC. The dealer fitted a Kubota loader (actually manufactured by Tenias in Spain).
I have a tipping trailer with a 3 stage SA cylinder which has worked fine on my B1750 although it is a pain in the tush having to switch between 3 point lift and tipping pipe with the little valve under the seat.
Anyway I thought I would improve my life with the dedicated aux spool on the EK1. It doesn't even have a valve to switch between tipper and 3 point lift
.
The dealer told me 'it will be fine' just connect the SA tipper to one of the QC's. It wasn't. The tipper raises but won't come down (as I suspected). I had planned for this and so swapped the single DA spool for a monobloc with 1 DA and 1 SA spool. Connect the tipper to the new SA spool- tipper goes up with spool in one position - and then goes up some more (though more slowly) with the spool in the other position. WTF???
After some head scratching and pipework chasing I deduced the following:-
So further deductions:-

After some head scratching and pipework chasing I deduced the following:-
1. The Tank connection from the spool goes directly to the 3 point hitch control block and must have some sort of restriction in flow such that a DA arrangement will go to tank OK as its under more pressure than my SA arrangement
2. The restriction is causing small backfeed of pressure so that when my SA spool should be emptying to tank it is actually filling the ram a bit more.
So I move things along by taking the tank connection from the spool off the 3 point lift hitch control and connecting with a T to the loader tank return. Now we have a slight improvement. Tipper goes up OK and comes down although pretty slowly. More weight in the tipper increases the down speed. Turn the engine off and the down speed is great and as expected.So further deductions:-
3. The T in the tank return is shared with the loader and as the loader spool is open centre there is not enough pressure from the tipper going down compared to the returning pressure from the loader
4. The 3 point hitch no longer lifts 

). The tank out from the spool must act as the Pressure in for the 3 point hitch.
So before I completely lose it does anybody recognise and agree with my deductions and any suggestions about what to do next?
