Lawn and Garden — FAQ
Can one electric trimmer handle both weeds and hedges?
String trimmers cut weeds and grass; hedge trimmers cut woody shrubs. They're different tools. However, some string trimmers convert to edgers. For complete backyard care, you'll need both a string trimmer and a hedge trimmer, or a pole system with interchangeable heads.
How many amps do I need for an electric string trimmer?
For typical backyard weeds, 3-4 amps suffices. For dense growth and tough grasses, choose 5-6.5 amps. The BLACK+DECKER 6.5-amp model handles overgrown areas without stalling, while 3-amp units work best for light maintenance on small, tidy properties.
What's the real battery life on cordless trimmers?
Expect 15-25 minutes from 2.0Ah batteries and 30-45 minutes from 4.0Ah batteries under normal load. Heavy weeds reduce runtime by 20-30%. Dual-battery kits effectively double working time, but corded models remain superior for jobs exceeding one hour.
Are electric trimmers powerful enough compared to gas?
Modern electric trimmers match gas performance for residential use. Corded models offer continuous power; premium cordless units deliver comparable torque. Gas still leads for commercial brush clearing, but electric wins for backyard maintenance with less noise, no fumes, and minimal maintenance.
How do I maintain an electric trimmer?
Clean debris after each use, check for loose fasteners monthly, and store indoors. For string trimmers, keep extra spools ready. Hedge trimmer blades need occasional lubrication with light machine oil. Cordless batteries should stay charged between uses and store at 50% charge over winter.
What safety gear do I need?
Always wear safety glasses to protect against flying debris. Long pants and closed-toe shoes prevent cuts. Gloves improve grip and protect hands. For hedge trimmers, consider ear protection as noise exceeds 85 decibels. Never operate without the blade guard installed.
