More information might be needed.... Did this happen all of a sudden? Or is this a new tractor for you?? Have you checked the rockshaft valve, if fully closed it can shut off hydraulics to the 3pt lift. If it's open, then there maybe something gone wrong inside the rockshaft???
Can't help you with the leaf sucker question....

Welcome to TBN
Yes, more info needed...does the rockshaft lever mover freely? Is the linkage that connect the lever to the tranny damaged? Can you manually lift the arms?
As for the "leaf sucker", I have never heard of that, and a google search of AMV8 just turned up Aston Martin info...and I don't think they made implements. Is it from JD? But it sounds like you need another rear remote.

Only if it has it's own valves, but you are not giving us any information to help you...

the mover moves freely and the bar that runs under the seat moves with it reaches the hydraulic box to the drivers left without a problem.
the arms are easily lifted (without anything attatched)
as for the blower i have my doubts if it is genuine JD although it was advertised as such (if we ever get it going it looks a handy piece of kit none the less.
I dont have a manual for either machine so sorry about the lack of info.

Assuming that's a PB circuit.

Would controls G and F have any bearing on your problem.
Not F - that's the lockout for the FEL. No effect on the 3pt arms. Now, if you turned the G knob down good and tight - well, "no worky, lifty arms, GI"!
I assumed that the rear SCV's were.. well, SCV's not the Power Beyond circuit. 'Cause if they were the PB circuit... well, the OP would be wondering how to replace a burned up main hydraulic pump. No hydraulic fluid circulation at all... very warm!!

Well I was kinda waiting for his "And what's that squealing noise ?"

No
