If you don’t want to spend too much on a good gas trimmer, consider the Poulan Weed Eater Featherlite SST25. At around $100, consumer Reports rated it a “best buy”. It is a straight shaft model and gets below shrubs and bushes better than the curved trimmers. The engine is gear driven which makes it quieter than some other gas yard trimmers and it performs very well for a gas yard trimmer in this price range. People like the adjustable handle that lets you slide it up or down the pole for a good fit. Other top features include a throttle trigger, stop switch, 25cc 2-Cycle, line limiter blade and a 17″ Cutting Width.
