3 Ways to Cut Your Electric String Trimmer Energy Bill
- 🌱
Trim when grass is dry for cleaner cuts with less motor strain.
- 💡
Keep the trimmer line at the proper length — too long creates drag, and too short means more passes.
- ⚡
Use a sweeping motion rather than pushing into thick growth, which bogs down the motor and spikes energy draw.
