To keep your lawn looking great, a gas-powered trimmer can be a valuable tool.

When it’s time to purchase a trimmer, keeping a few considerations in mind will ensure that you’ll select a model that meets your needs.

Equipment dealers can be a helpful resource in the selection process.

Consider the following checklist of features to discuss with your dealer when you’re selecting a trimmer:

• Good power — Trimmers with 0.9 horsepower or more will handle thicker grasses and weeds. Make sure the trimmer starts easily and accelerates rapidly for maximum efficiency.

• Low weight — A lighter trimmer causes less fatigue, so compare the weight with the power to determine a favorable ratio for your application.

• Shaft configuration — A curved shaft is most common for homeowner use with its lower cost and lighter weight; a straight shaft trimmer, designed for more demanding jobs, is easier for reaching under hedges and bushes.

• Vibrations — The unit should have an efficient vibration-reduction system to make it easier to control and less tiring to operate.

• Comfortable operation — Make sure the trimmer is easy for you to handle, with ergonomically designed controls.

• Emissions — The engine should have some form of emission control, for the benefit of your working environment as well as your neighborhood.

In addition, take into consideration the size of your yard and how often you’ll be using the trimmer.

By evaluating all of these factors, you can be prepared to make a well-informed decision when purchasing a new trimmer.
