MF1533 SyncroShuttle has no PTO power

[Dmacleo]

may want to check/trace wiring from pto switch back to pto itself. may have a broken wire making the clutch actually do nothing.
do not remember where wire runs are on these units.

Dmacleo,
Great idea. Looks like the PTO solenoid is under the left floor, behind the frame :-( Hopefully there's a connector with easier access in the console.

still need to check wiring before and after solenoid. if all that happens is light on dash comes on something is not right.
if I remember right with engine off and key on you should hear the solenoid click (or if possible feel it click) when switch turned on but don't quote me on that.

Following the wiring diagram in the Operator Instruction Book (pg D-27), I've verified voltage and continuity off the PTO switch, diode, ECU (in and out). The wiring gets lost in the bundle (cable assembly). Next check would be item 35, the PTO Control Solenoid Valve. What's most frustrating is I cannot find that solenoid. Looking at AGCO parts book online (pg 486), it shows a solenoid for the PowerShuttle as being on left-side under where the Brake Arm is but none listed for the SyncroShuttle (mine). Since the PS and SS are very similar, I looked in that spot and the SS is bare metal.

Online parts guide pg 496, "HYDRAULIC SYSTEM - SUB HYDRAULIC SYSTEM(2/2), SYNCROSHUTTLE TYPE FROM S/N S4900" shows what appears to be a solenoid/valve in top/right corner but it has no reference number that I find and doesn't have any clues (that I see) to its location.

Next most-likely spot seems like it'd be on the right near all the valves, but I can't tell which (if any) it is.

Hoping someone has another reference or experience to guide me to the SyncroShuttle's PTO Control Solenoid Valve.

You’re missing your PTO shroud, and hydraulic fill plug, unless you just removed the plug temporarily, that could explain your milky oil.
From the photos and your issues, it looks like it’s had a pretty hard life for only 599 hours.

Yes, I have the plug; 'fluid change ops' were happening in that pic.

I do not have whatever would be in the lower circle. Searching AGCO online parts book, the only thing called 'shroud' is at the radiator. Any other information?

Would you happen to know where the PTO Control Solenoid Valve is located on the SyncroShuttle model?

They call it PTO protection

DarkBlack,
Are we looking in the same place? It looks like a useful part but not seeing it in the TOC for my model.

Offhand no. It should run through the third from top fuse, though. Have you checked for current and voltage on that wiring? It’s a 15A fuse. Maybe you can follow the wiring from the fuse block
