Lawn and Garden — FAQ
What exactly does a rotary edger do?
A rotary edger uses a spinning vertical blade between wheels to slice clean lines where lawn meets pavement. Unlike string trimmers, it creates crisp 90-degree edges without scalping grass or leaving frayed tips. Manual models rely on pushing force; power attachments spin the blade via trimmer engine.
Manual vs. powered rotary edgers: which is better?
Manual edgers cost 80% less, weigh half as much, and require zero maintenance. They excel on maintained lawns with light overgrowth. Powered edgers tackle heavy sod and thick weeds faster but cost $150+ and need fuel or batteries. For typical suburban lots, manual delivers better value and control.
How often should I edge my lawn?
Edge sidewalks and driveways every 2-3 weeks during peak growing season (spring/early summer). Monthly edging suffices in heat of summer and fall. Established edges take 5 minutes per session; letting growth go 6+ weeks turns a quick job into a 30-minute battle. Consistency beats brute force.
Does handle length really matter?
Absolutely. A 69-inch handle suits users 5'8" to 6'2" without stooping. Shorter 48-inch models force tall users to hunch, causing back strain. Conversely, petite users struggle with oversized handles. Adjustable designs solve this, letting multiple family members work comfortably. Measure your height and test reach if possible.
Why are some wheels wider than others?
Wide wheels (3+ inches) act like train rails, keeping the blade perfectly vertical on curves and uneven ground. Narrow wheels (2 inches) work fine on straight, flat concrete but wobble on slopes. Dual-wheel designs add stability for beginners. Rubber compounds grip wet surfaces; hard plastic slides.
Can I replace the blade when it dulls?
Yes, and you should. Quality replacement blades cost $8-$15 and install with one bolt. Most budget edgers use standard 7-inch or 9-inch blades available at hardware stores. Replace annually for heavy users or when edges look torn instead of sliced. Always disconnect the blade before storage to prevent accidental nicks.
