The Best 4 Cycle Grass Trimmers

Robin BH2500

• If you need a relatively lightweight grass trimmer that can provide plenty of cutting ability for tough weeds, consider the Robin BH2500. Weighing just over 11 pounds, this four cycle engine model comes with a shoulder harness for comfort during long trimming chores says Grounds Maintenance Magazine. The solid state ignition device on the BH2500 makes starting it easy, especially when compared to starting a traditional two cycle engine. While almost all gas powered trimmers require a special gasoline and oil fuel mixture to run properly, this model requires only gasoline. Some homeowners may find it too expensive for their budget because it is designed for light commercial use.

Honda HHT25SLTAT

• Honda motors are known for their reliability, and Honda powered four cycle grass trimmers are no exception. With EPA approved low emissions levels and quieter operation than a two cycle model, the HHT25SLTAT also has enough power to handle regular yard maintenance jobs easily says the String Trimmers Reviews website. Its 25 cc engine can handle some of the toughest and thickest weeds that might grow in your lawn, and will cut through grass quickly and efficiently. This string trimmer features a semi-automatic line feeding system that doesn't require the same maintenance as either manual or fully automatic feed systems. Homeowners may find it difficult to see the cutting line clearly when trimming near delicate garden plant due to the large debris guard.

Lehr Eco Propane Trimmer

• Not all four cycle engines require gasoline. The Lehr Eco Propane Trimmer is powered by disposable canisters of compressed propane gas, according to Popular Mechanics, which creates an efficient and quiet running lawn trimmer. Unlike other gasoline alternatives like corded electric or battery powered models, this trimmer doesn't suffer from a reduction in power and can cut through the same weeds and grass as a powerful gas trimmer. It can run for approximately two hours on one canister, making it slightly more expensive to operate than a four cycle gasoline model that doesn't require an oil fuel mixture.

Makita EM4251

• Miniature four cycle engine grass trimmers are lightweight but powerful, and the Makita EM4251 is one of the best models in this category. With a fully fueled weight of just under 12 pounds, this professional model can cut through tall grass or difficult weeds without becoming a strain on your arms. This model also produces 15 percent less noise at top speeds says Grounds Maintenance Magazine, and has lower speed settings for further noise reduction when top cutting power isn't needed. Since this model is intended for heavy residential work or medium commercial use, it is more expensive that less powerful models.
