LOOK in this area, if you have a knob there, turn it counter clockwise.

On the HST model there will be a quarter turn there but it is an extra return point and should be closed with a bull plug in it. ? (Memory&age)

On posted picture the TPH control is shown. Further down on it is a rod with a sliding adjustment. The problem may lie in that area??

I am referring to the lift lever that raises the 3ph. the valve is inside the trans most likely. It may require a lot of tear down to get to it. That is a last resort.
I would make sure the drop rate control valve is open. It should screw open so you can control the rate of drop.
As Egon has mentioned his b7100 does not have such a valve.

Thanks guys problem sorted today. turns out problem was with the orange coloured plug immediately behind r/hand seat mounting. I think it was "bumperm" who referred to this so thanks for assistance and a big thanks to all who offered help. If you're ever in my neck of the woods, the drinks are on me!!!

The Kubota b7100 HST I had did not have such a valve. On mine adjustments were on the control lever slide for stop points. No rate of descent valveing.

Egg on face!!

After reading the solution found the information on page 27 of the operators manual.
