If you are a time-served landscaper/gardener, as I am, you'll be familiar with cutting and rolling your own turf and transporting it to a job?
It was a very manual task. And hard work.
By the time the turf had been cut, rolled by hand, lifted onto a truck and then unloaded on site, one was rather cream crackered by the time it came to lay the turf.
It's a bit easier today:)
