Thanks for the advice, but once upon a time I seem to remember spreading
(watering can) a chemical on the lawn which attracted worms to the
surface.
Raked them up and dumped them on the compost heap.
I could be wrong, but I note that the acres of greens on golf courses are
devoid of worm casts.

There is such a product, but (and its a big one!) without the worms golf
courses have to do all the work the worms do in order the grass can grow, so
you can get rid of the casts but it will cost a lot of time and money to
have a nice lawn without any, or you can invest in a birch broom or similar
and simply quickly whisk over the surface before using the mower.
