Amazone sprayer on a Massey dyna vt

Massey 6470 said:

Occasionally I have to put my amazone uf 1602 on a massey ferguson 6718S dyna vt (normal tractor is a 6713S dyna 6) - the sprayer hydraulics work off the load sensing pipes on the tractor, when on the Vt it will switch off the front suspension or make it work funny as if it’s starving it of oil. The only way to get it to function properly again is to press the suspension button while either raising or lowering the sprayer boom- basically making the load sensing system at the same time but it soon deactivates again. Has anyone found a Similar issue with a vt using load sensing, it’s perfect on the dyna 6.

I suspect it's a shuttle valve issue.
I used to use a trailing shoe on a tank with a 76 and 7726. As soon as the macerator was spinning the front suspension used to mess about. When you switched it off in the field and back on for the road it was fine.
Dealer being an MF one was clueless

Have you another tractor to try it on before you start digging into the tractor?
