  • Loop Handle (R) - Loop handle grass trimmers and brushcutters are ideal for trimming between bushes and shrubs and other areas where space is limited.
  • IntelliCarb™ Compensating Carburetor - The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.
