STIHL FS 240 R Gas-Powered Professional Trimmer, 37.7cc

The STIHL FS 240 R steps up to a 37.7cc engine for professionals covering large properties where lower-displacement trimmers would need frequent refueling or bog down in denser growth. STIHL's IntelliCarb compensating carburetor keeps engine RPM consistent even as the air filter accumulates dust over a workday, reducing performance drop-off between cleanings, while the TapAction AutoCut head advances trim line with a simple tap rather than manual feeding. STIHL cites 20% better fuel efficiency versus the previous generation of this model.
