I want to try lowering parts of my lawn by using an aerator to pull out

with gang mowers so can't remove the cuttings.

As well as what the others have said, my experience of a hollow tine
aerator is that the tubes very rapidly block and it ceases to work.
You spend ten times longer clearing the tubes than hollow-tining the
grass. They're a right PITA!

Cut the grass into squares with a half-moon edging tool or sharp
spade, lift the turves, remove some soil and replace the turves.

Or raise the slabs.

The slabs need to be lifted and re laid.
The worms in the lawn bring soil to the surface so that over time the
lawn rises, but as they can't do the same where the slabs are the
slabs seem to sink into the ground.
