How big is the cutting area and where (house lawn, dusun, kebun)?

Black and decker push trimmer should be ok.
It is quite light weight and he just needs to push it around like a vacuum cleaner. Can detached the trimmer when needed. You can buy spare string and sendiri wind the string after the string finished.

Just buy another 10-15 meter power extension and he can cut entire house.

Dont buy battery type as it might too heavy if use as trimmer.
Dont buy roller cutter because those wont roll if the lawn is not level and too long.
