WASHINGTON - Vermeer Manufacturing Co. is recalling 140 model-year 2009-2011 BC1200XL single-axle brush chipper trailers. 

During the assembly process, the wrong lug nuts were installed on wheels for the 285/75/R16 flotation tire option, the National Highway Traffic Safety Administration reported. These incorrect lug nuts may loosen, since they don't match the countersink holes in the wheel disc. Loose lug nuts can damage the wheel disc and result in wheel separation from the trailer, posing a safety risk. 

The trailers covered by the recall were all manufactured from July 24, 2009 through Feb. 14, 2011. 

Dealers will replace the lug nuts free of charge. The safety recall is expected to begin next month. 

Owners can reach Vermeer at (641) 628-3141.
