Engineered for rugged dependability and professional results. The BDS 43/175 C is a 17" single-disc, single speed machine. Utilizing cast aluminum housings rather than poly or stamped frames, this BDS machine is built for durability. The new cord strain relief system minimizes cord breaks, kinks and tears. Mechanical safety interlock prevents accidental start-ups, and a built-in circuit breaker protects the motor.
