String Trimmer Info
Electric String Trimmers:
- Least expensive
- Relatively light weight and easy to handle.
- Lower operating costs.
- Ideal for smaller lawns.
- Environmentally friendly.
- Limited by the length of the cord.
- Cordless string trimmers provide freedom from a cord but only give users about twenty minutes per battery charge.
- Cordless string trimmers are less powerful â€“ usually works well on grass but not strong enough for tough weeds.
Gas String Trimmers:
- Excellent for larger lawn areas.
- Handle toughest weeds and tall grasses.
- No cord limitation, but need for gasoline storage.
- Need for maintenance.
- Noise pollution.
- Heavier machines.
- Spring-assisted starting feature is an advantage for gas trimmers as it makes pulling the starter cord easier.
- See-through fuel tanks are an added advantage, since they make it easier to measure at a glance how much gas is left in the tank.
- Gas string trimmers are usually the heaviest of the three types, so a shoulder strap or a harness helps with ease of use, support and prevention of back problems.
- Gasoline use pollutes environment.
Propane String Trimmers:
- Powerful machines that handle stubborn weeds easily.
- No cord limitations, can handle large land areas.
- Start up is easy - no priming required, no choke.
- Environmentally friendlier â€“ propane is less polluting than gasoline.
- Each 16.4 ounce propane canister (costing about $ 2- $ 5) gives about two hours of use and is not recyclable.
String Trimmer Engines:
2 stroke engine
- More fuel efficient engine
- Emits more pollution
- No cord limitations, can handle large land areas
4 stroke engine
- Quieter machines.
- Cleaner to burn - emit up to 75% less pollution than 2 stroke.
- Use straight gasoline, instead of a gas/oil mix.
- Operate smoothly, with less vibration.
- 4 stroke engine can be tilted in any direction, without fear of damage.
- Heavier machines â€“ a shoulder harness might be required.
- Require regular lubrication and maintenance.
- More expensive.
