Backpack Blower

Echo PB-500

2-Stroke

The Echo PB-500 is a 50.8cc <!-- verify: echo-usa.com --> 2-stroke backpack blower in Echo's commercial PB lineup, designed for production landscaping, large property management, and commercial leaf clearing. It delivers high air volume through a professional backpack chassis with padded shoulder and waist straps. The PB-500 runs a Zama carburetor. Under daily commercial use, monthly fuel system inspection (primer bulb, filter, lines) and air filter maintenance are routine. The PB-500 strikes a balance between blowing power and total unit weight for operators who run the blower for multiple hours per shift.
