Reduce the noise without sacrificing the power. The STIHL BR 500 features a powerful, low exhaust emission and specially designed muffled blower tube so that it operates at a quiet 65 dB(A). This makes the BR 500 an excellent choice for use in residential neighborhoods or in municipalities with noise restrictions. The blower also includes a two-position adjustable blower tube, giving you greater control over its powerful air flow. Note: Not available for purchase or delivery in California
