The Boston Public Works Department says a Woburn company will build the city two truck-mounted snow blowers that will give us Montreal-strength street-clearing power.

Each of the LaRue D55 blowers can shoot 2,750 tons of snow an hour the length of half a football field, although in practice the blowers, to be mounted on new Volvo loaders, will be paired with large dump trucks, into which snow will be blown for transportation to one of the city's fine snow dumps.

The city will pay $645,000 for the new blowers and loaders to Woodco Machinery, Inc. - the only company to meet the city's specifications.
