Description
Underpowered commercial trimmers choke and wrap long weed fibers when sweeping through heavy roadside vegetation and overgrown ditches. The Shindaiwa 20in 30.5cc Straight Shaft Trimmer For Brushcutting powers through thick woody brush with a high-displacement two-stroke engine. It features a wide 20-inch cutting swath. Heavy engine displacement requires firm two-handed control.
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 inches in diameter because sudden blade binding will bend the solid drive shaft. Never run the machine on straight gasoline without two-stroke oil mix.
- Clean grass clippings and mud from the engine cooling fins and starter housing after each shift.
- Pump high-temperature gear grease into the lower gear case plug hole every 25 hours of use.
- Inspect the air filter element and blow dust out with dry compressed air every 50 hours of use.
