143R Clutch Assembly for Brush Cutter Grass Trimmer Replacement

This clutch is customized for 143R garden engines. Thick cast steel shoes maintain stable shape under continuous vibration during heavy-duty brush cutting. The sintered friction lining boasts excellent heat and wear resistance against high-speed friction. The heat-treated heavy-duty spring is anti-fatigue with consistent rebound performance. The shoes expand to drive cutting tools at high rotating speed and retract to cut power at idle for easy operation. Standard mounting holes enable fast tool-based installation without modification. Dustproof and shock-resistant, it works reliably on farms, hills and green belts. Compatible with all 143R brush cutters and trimmers, it reduces maintenance frequency and delivers long service life for outdoor weeding work.
