Saw a chap take down a big conifer four/five years ago. He used
four saws to do the job. A small one at the top, then working down
until he used the big one to cut the trunk. Very impressive to watch.

Yeah, watched a pro take down a whole line of very big palm
trees along a neighbour's back fence line with no access at all.

None?

Yep, none. That neighbour had no access
to the back yard at all for other than people.

So did he only take them down level with the top of the fence?

They werent that close to the fence, easy enough
to cut them off right down to the ground from
beside the trunk along the fence.

He did it with spiked boots

More likely strap on 'spikes' / 'irons'.

and a belt chain

Wire strop.

and a chainsaw,

Much quicker than a bow saw ...

starting at the top

Best place when chogging a tree down. ;-)

and then taking off big chunks

Chogs.

We don't use that term here at all.

of the trunk as he came down the trunk.

Std practice.

Should have videoed it.

Have you heard of Youtube? ;-)

Nope, never heard of it at all.
