GASOLINEBest for larger properties where trimming is far from an outlet. Also better for tall grass and weeds.
But gas trimmers are noisy and require pull-starting, fueling, and maintenance. Four-stroke models free you from mixing fuel
and oil, but they're heavier.
Price $70 to $250 for most.
CORDED ELECTRICBest for small yards. Most are light and inexpensive. All offer push-button starting and free you from fueling, maintenance, and exhaust
fumes.
But even the best aren't as good as the best gas models in tall grass, and are nearly as noisy. All limit trimming to the length
of an extension cord (typically 100 feet).
Price $20 to $100 for most.
CORDLESS ELECTRICBest for trimming short, sparse grass on small properties where trimming sessions are short and your trimming needs are minimal.
But trimming time is typically just 15 to 20 minutes per battery charge. Recharging can take as long as 24 hours. All cordless
trimmers are relatively anemic in grass, ill-suited for tougher weeds, and pricey for their performance. They're also less
balanced, making them harder to handle.
Price $30 to $100 for most.
