BLACK+DECKER LST522
Score: 78/100Rankings

The BLACK+DECKER GH900 is a lightweight, corded electric 2-in-1 string trimmer and edger featuring a powerful 6.5 Amp motor and a 14-inch cutting path. It is designed for residential use on yards up to 1/2 acre, offering high-torque performance for tough weeds and an automatic feed spool system for continuous line feeding. The main trade-off is the restriction of the power cord, which limits mobility compared to cordless models.

The BLACK+DECKER LST522 is a versatile 20V MAX cordless string trimmer and edger featuring a 12-inch cutting swath and automatic line feed. Its PowerDrive transmission and convertible design make it ideal for routine yard maintenance and edging. However, it may struggle with very dense overgrowth and battery life is limited on high speeds.
