Rather than have fleets of noisy grass cutting machines patrolling golf courses, why not build golf carts with integral mowers?
These could be electrically motorised and thus operate quite quietly.
Every round played would save some money and pollution and the resulting cuttings could be dumped automatically in a pile on the way to the 19th hole.
If a golf club had a wide variety of abilities among its players, then the fairways would be adequately mown over time and the rough too would be greatly improved.
(The greens keeper would still be kept busy, though, with his or her specialist grass cutters).
