Well, it's the kind of guy I am! But also I want to do more than just power a
winch with the hydraulic PTO - there are several other pieces of gear I have
access to which are hydraulically powered, and setting the vehicle up so that
it can be used as a hydraulic power pack is part of the scheme.

Not sure I understand this - the PTO fits straight on the back of the
transfer box, does it not? The drive shafts come off the side of the tfr box
so fitting a hydraulic PTO does not involve disturbing the drive shafts. Or
am I talking bollix?

I've got a fairly small hydraulic winch with a 1t pull which will do most of
what I ever need - one person can pick it up so it's not overly heavy. It's
not a Landrover standard fitting of any sort, but I've got a well equipped
metal working shop so I don't anticipate problems making an adaption to fit
it. I'm thinking perhaps about something which can be taken on and off the
vehicle with a few bolts or locking pins.
Next, what kind of fluid with the PTO take?

I have to say this doesn't make sense to me either - yes the PTO will be on
the same oil circuit as the tfr box but I'd have thought the hydraulic fluid
circuit through the pump and whatever the pump is driving is completely
isolated from the transfer box oil, unless the seals on the pump shaft are
knackered. But again maybe I'm talking bollix.

fair point.

I've spent enough time working on hydraulic power presses that I'm familiar
with the fact that all hydraulic systems leak. But I'd not expect it to be
significantly worse than the lubrication leaks on the vehicle anyway. It's 16
years old and used primarily as a play thing so it's not as if I need it to
be clean and tidy.

Thanks for your comments - food for thought!
Nick.
