Sheep have taken over the job of lawnmowers and maintenance workers in parts of Turin, Italy, according to Ananova news service. But in some cases city police are having to do shepherd’s work moving the sheep along traffic lanes from city lawn to lawn.

The city is employing about 700 sheep keep grass verges and lawns in city parks neatly trimmed. Environment officials in Turin said they were spending about $48,000 a year to cut the grass for just one of the bigger city parks. Now their lawn mowers do not require gasoline and the “mowers” can be sold at the end of the grass cutting season to bring money in to the city coffers.

Some complaints have been lodged. Drivers don’t like the sheep roadblocks when the flock is being moved, and park visitors complain about the fertilizer left behind by the grazing lawnmowers.
