Husqvarna 525L

2-Stroke

The Husqvarna 525L is a 25.4cc <!-- verify: husqvarna.com/us --> 2-stroke professional-grade straight-shaft trimmer in Husqvarna's commercial lineup, built for landscaping crew daily use with a commercial-grade gearhead and professional handle configuration. It runs a Zama or Walbro carburetor <!-- verify: husqvarna.com/us --> and accepts professional trimmer heads and rigid brush blades. Under daily commercial use, monthly fuel system inspection, air filter service, and gearhead grease repacking are routine. Lighter than the 535 and 545 series, making it popular on crews where trimmer weight and operator fatigue are primary concerns.
