Seriously consider hiring a digger for a day - £150 maybe top price.
Even if access is limited you can

- trench down each side
- and if necessary cut any lateral roots with a chainsaw or handsaw or
hatchet or even a hand axe.
- with luck trench in front of it as well.
- then usually it can be lifted out snapping what laterals are left, or
if it is tall, pulled over from the top. Then the remaining roots are
exposed and can be cut.
- finally the soil levels can me made good with the digger using the
blade as a grader.
- the digger can be used to cart the stump away to the bonfire too
- and driving a mini digger is FUN.

Thanks TNP! I won't be doing that, mainly because the hedge is between
a shed in the garden, and a narrow country (but busy!) lane, so it won't
fit. But I'd need the hedge to be in the middle of the neighbouring
field, for an hour or two's cack-handed experimentation, never having
driven any such machine before.

But thanks for the entertainment! I can almost see you, tearing around
on your toy-for-day! Thumbs-up!
