Slurry tanker hydraulics pulsing ( pic hon)

[Classichay]

I’ve a slurry tanker in when the hydraulics are used for the arm or functions cause pulsing of the lines very severely, it’s got a free flow return to the tank. Any ideas?

Now Then..
What tractor is it on?? How many functions does it have?? Does it have its own spool valve??
Have you tried turning the oil flow down on the tractor spool??

It’s got three functions with an electronic spool block, lift the lazy arm, open the rear door and the rear linkage. It’s currently fitted with a splash plate.

Yes have tried turning the oil down on the spool , have tried it on two cases 200 and 185 cvx puma.
