Frequently Asked Questions About String Trimmers
What's the difference between a straight-shaft and curved-shaft trimmer?
Curved-shaft trimmers are shorter and lighter, making them easier to handle for casual use around a smaller yard. They’re comfortable for most homeowners and less fatiguing for shorter sessions.
Straight-shaft trimmers have a longer reach, which means less bending when trimming along fence lines or under shrubs. They also accept a wider range of attachments (edger blades, brush cutters, etc.) and tend to have more powerful engines. Professional lawn crews almost universally use straight-shaft — it’s more versatile and holds up better over time.
If you’re trimming a small suburban yard once a week, either works. If you’re doing fence lines, large properties, or you want a tool that grows with your needs, go straight-shaft. The team at James Lawnmower can help you decide.
What trimmer line should I use?
Trimmer line comes in different gauges and shapes, and the right choice depends on what you are cutting.
For typical residential grass and weeds, .080 to .095 inch round line is standard. For tougher weeds and heavier growth, stepping up to .095 or .105 inch makes a real difference. Twisted or multi-sided line (star, square, pentagon) cuts more aggressively than round line of the same gauge and tends to last longer — it is worth the small price premium for most homeowners.
One of the most common mistakes is using line that is too light for the job. The team at James Lawnmower stocks a range of options and can tell you exactly what works best for your trimmer model.
