Cutting Ability of String Trimmer Mowers

General Use

• Most string trimmer mowers are designed to cut through grass, tall weeds and small saplings less than 1/2-inch thick. Effectiveness varies depending on the model and the product. The machines use a durable string mechanism that whirls at high speeds to cut down plant material. A common consumer complaint is that the springs break easily or grass becomes clogged in the trimming mechanism.

Heavy Duty Use

• A few models have an optional attachment that enables the machine to cut through wood up to 3 inches thick. This attachment is not a string, but is actually a chainsaw blade, and is available on high-end machines. Move machines that lack a heavy-duty attachment slowly through dense weeds and grass to avoid clogging the machine.

Considerations

• String trimmer mowers are a fairly recent addition to the lawn care market and don't have a long track record. The Lowe's website offers only three machines, all manufactured by the same company. Carefully research a company's history of reliability and read online reviews before purchasing a machine. In general, higher-priced machines have a stronger motor and are able to cut through grass and weeds more efficiently.

Safety

• Consumers also complain that string trimmer mowers throw back rocks and other debris with great force, potentially causing injury. Look for a mower that has a wide, sturdy safety guard and wear eye protection when you use the machines. A string trimmer mower mows down anything in its path and can cause damage to trees and fences if not carefully operated.
