Grimme GZ diablos shoving

[Fen Farmer]

As above, we are experiencing issues with the diablos on our GZ shoving soil on occasions and not turning/ flowing properly as it should. We are on extremely light black fen so not the easiest of soils to work with.
We have tried moving the diablos in the bolt holes into the forward most position to see if it helped things with flow of soil.
Also we have tried with more diablo pressure set on the controls to see if that improved things with little success. Would high diablo pressure help with the diablos turning or would it just cause it to shove more instead?!
Any advice welcome!
Thanks

Keep the scrapers as tight as you can.but not to bind ,,used to have the same problem on a reekie except it was blow away sand ,,they couldnt sense the loose ridge top ,,
