Description
Light-displacement string trimmers bog down and wrap stems when cutting dense woody weeds, berry vines, and thick brush along highway guardrails. The Echo Grass Trimmer/Brushcutter 30.5cc 17in Speed Feed 400 machine cuts tough woody saplings with raw two-stroke gas torque. It swings a 17-inch string head or steel blade. Prolonged clearing requires wearing the included shoulder harness.
A commercial 30.5 cc two-stroke engine features a chrome-plated cylinder bore and a forged connecting rod supported by caged needle bearings for continuous high-RPM running. The drive line houses a solid steel splined drive shaft supported by greaseable bronze guide bushings inside a heavy-wall aluminum tube. The cast-aluminum angle gear head features spiral bevel gears running inside a grease-packed gear housing.

Brush Clearing Scope Maintenance Protocols
Commercial land clearing crews, highway verge mowers, and estate groundskeepers clear overgrown trails fast with this rugged brushcutter. Do not attempt to fell trees thicker than 2.5 inches in diameter because sudden blade binding will bend the solid drive shaft. Never operate the machine without the steel brush blade deflector shield.
- Inspect the metal brush blade for balance, cracks, and edge sharpness before starting each clearing job.
- Pump high-temperature gear grease into the lower gear case plug hole every 25 hours of use.
- Clean wood fibers and weed wrap from around the lower blade arbor after each work shift.
