Description
Flexible cable drive trimmers snap internal wire cables when operators clear heavy weeds around guardrails and bridge abutments. The Efco Professional Trimmer Loop Handle – 1.5 HP/30cc Solid Drive Shaft uses a rigid solid steel shaft to transfer continuous power without torsional cable failure. It carries a 30 cc commercial engine. Compact loop handle requires two hands for balanced weed sweeping.
A commercial 30 cc two-stroke engine features a forged steel crankshaft, two-ring piston, and chrome-plated cylinder bore to maintain compression through thousands of commercial hours. The drive line employs a 7 mm solid steel splined shaft housed inside an extruded aluminum tube supported by six self-lubricating bronze bushings. The commercial gear head features heavy spiral bevel gears housed in cast aluminum.
Solid Steel Shaft Commercial Trimmer Platform
The rigid solid steel drive shaft eliminates cable windup and delivers instant cutter head acceleration when opening the throttle. The compact loop handle provides outstanding maneuverability in tight cemetery and estate grounds.

Commercial Grounds Maintenance Directives
Landscape contractors, cemetery caretakers, and municipal grounds maintenance crews clear tough perimeter weeds fast using this solid-shaft trimmer. Do not run this machine on straight gasoline without two-stroke oil mix because piston seizure will ruin the engine within minutes. Never operate the trimmer without the plastic debris deflector guard.
- Clean grass clippings and dirt from the engine cylinder cooling fins after each workday.
