Hi Steve, as usual, good advice from Grumpy there, mate. If in doubt, use a fine rake and drag it all back into the garden.
For my edging I use a Victa Tilt-A-Cut which throws the grass and litter forwards, so I don't have much of a prob there.
For ferrous metallic objects, I removed the magnet from an old hi-fi speaker, tied a length of strong garden twine to it, so as I can drag it over the lawn, if I suspect I have lost a nut, bolt or screw.....better safe than sorry.
