YONKERS

It weighs 20 tons empty — 45 tons when full — smells a bit racy and has become known as the Yonkers Chomper. Lumbering down a street in southern Yonkers on Monday, it made quick work of the mountain of garbage piled in front of an apartment building and still had room to polish off a few piles down the street.

Children seemed delighted by its saw-toothed jaw and polka-dotted body. Adults tended to warm to it after learning that the whimsical bit of street theater they were watching had not cost taxpayers a thing.

Some cities commission murals to bring art to the masses. Others design sculpture parks. But Yonkers took a different tack last month when it outfitted 6 of its 45 garbage trucks to give residents something less drab to look at each morning. The experiment has been such a success that residents asked to have the truck routes alternated to let the artworks tour the town.

“We’re going to rotate them so more neighborhoods can see them,” said John A. Liszewski, the commissioner of the Public Works Department for this city of about 200,000. He would like to see the rest of his fleet undergo makeovers if his staff can attract more private sponsors.

“I’m becoming the city’s arts commissioner,” Mr. Liszewski joked.
