The Ultimate Buying Guide for Gas Lawn Trimmers
Gas lawn trimmers, often called string trimmers or weed whackers, are powerful tools. They help you tame tough weeds and create neat edges around your lawn. Choosing the right one makes yard work much easier. This guide helps you pick the best gas trimmer for your needs.
Key Features to Look For
When shopping, look closely at these important features. They determine how well the trimmer works and how long it lasts.
Engine Power and Type
- Engine Size (CC): Measured in cubic centimeters (cc), a higher number usually means more power. For small yards, 25cc to 30cc is often enough. For thick brush and large properties, look for 30cc or higher.
- Two-Stroke vs. Four-Stroke: Two-stroke engines are lighter and simpler. You must mix gas and oil to run them. Four-stroke engines run on straight gasoline, are quieter, and produce fewer emissions, but they weigh more.
Cutting System
- Cutting Diameter: This is how wide the trimmer cuts with each pass. A 16-inch or 17-inch sweep is standard. Larger diameters cover more ground faster.
- Line Type and Thickness: Thicker line (like 0.095 inches) cuts tougher weeds better. Ensure the trimmer can handle the line thickness you plan to use.
Ergonomics and Handling
- Shaft Type: Straight shafts reach farther under bushes and decks. Curved shafts are usually lighter and easier to maneuver in tight spots.
- Handle Design: Look for adjustable or bike-style handles. Good handles reduce fatigue when you work for long periods.
Important Materials and Construction
The materials used define the trimmer’s durability. Good construction means your trimmer lasts many seasons.
Shaft and Housing
- Shaft Material: Aluminum shafts offer a good balance of strength and weight. Some professional models use stronger steel. Plastic housings are lighter but might crack if dropped.
- Engine Components: A chrome-plated cylinder inside the engine resists wear. High-quality bearings reduce friction and help the machine run cooler.
Factors That Improve or Reduce Quality
Quality varies significantly between brands and models. Pay attention to these details.
What Improves Quality?
- Anti-Vibration System: Good trimmers have rubber mounts that absorb engine vibrations. This greatly reduces arm and hand fatigue.
- Easy Start Features: Spring-assisted starting systems make pulling the cord much easier, especially on cold mornings.
- Commercial Grade: Tools marketed as “commercial” usually have stronger internal parts and can handle heavy, daily use.
What Reduces Quality?
- Thin Plastic Parts: If the housing or handles feel flimsy, they will likely break quickly under stress.
- Poor Carburetor Setup: Low-quality carburetors often cause starting problems, especially after the trimmer sits during winter.
User Experience and Use Cases
Think about where and how often you will use your trimmer. This guides your purchase decision.
Light-Duty User (Small City Lot)
If you only trim grass edges once or twice a month, a lighter, lower-powered, straight-gas four-stroke model might suit you. They are easier to maintain.
Heavy-Duty User (Large Acreage or Brush Clearing)
If you clear thick weeds, tall grasses, or work for hours, you need a high-powered two-stroke engine. These offer maximum torque to power through dense vegetation. Look for bike handles for better control.
Maintenance Considerations
Gas trimmers require regular maintenance. You must clean the air filter and spark plug. Always store fuel properly using a stabilizer to prevent engine gumming. If you dislike mixing oil and gas, choose a four-stroke model, though they usually cost more upfront.
Frequently Asked Questions (FAQ) about Gas Lawn Trimmers
Q: What is the difference between a straight shaft and a curved shaft trimmer?
A: A straight shaft trimmer reaches farther under obstacles like decks. A curved shaft trimmer is generally lighter and easier to manage for simple edging tasks.
Q: Do I have to mix oil with the gas for all gas trimmers?
A: No. Two-stroke engines require you to mix oil and gasoline according to the manufacturer’s ratio. Four-stroke engines use straight gasoline, just like a car.
Q: How often should I change the spark plug?
A: You should inspect the spark plug at the start of every season. Replace it if it looks damaged or fouled, which usually happens after about 100 hours of use.
Q: What size engine is best for thick brush?
A: For thick brush and heavy-duty work, look for an engine size of 30cc or higher. More power helps prevent the engine from bogging down.
Q: Can I use a trimmer line designed for electric models on my gas trimmer?
A: You can, but it is not ideal. Gas trimmers spin much faster and require thicker, more durable line (often 0.080 inches or larger) to handle the speed and power.
Q: What is “line advance” technology?
A: Line advance, or bump feed, is how the trimmer dispenses new line. You tap the head on the ground, and the mechanism releases more line automatically.
Q: Is a harness necessary for a gas trimmer?
A: A harness is highly recommended, especially for heavier models. It transfers the weight from your arms to your shoulders, reducing fatigue significantly during long trimming sessions.
Q: Why does my gas trimmer start hard after sitting all winter?
A: This usually happens because old gasoline or oil mixture breaks down and clogs the carburetor. Always use a fuel stabilizer or drain the fuel tank before storing the trimmer for the winter.
Q: Are gas trimmers louder than electric ones?
A: Yes, gas trimmers are significantly louder than battery or corded electric models. Always wear hearing protection when operating them.
Q: What is the benefit of having an adjustable throttle lock?
A: The throttle lock lets you set the engine speed at a constant level. This means you do not have to hold the trigger down constantly, which saves your hand strength.
