The Oregon 22-095 Gatorline is a heavy-duty string trimmer line designed for professional use. It has a .095-inch thickness and a square shape, which helps it cut through tough grass and weeds more efficiently than round lines. The spool contains 1,134 feet of line, giving you plenty of material before needing a replacement. Made by Oregon, a well-known brand in lawn care, this line is compatible with many string trimmers and comes as a genuine replacement part, ensuring reliable performance.

One of its strong points is the durability and cutting power, thanks to the square shape and thick diameter, which users appreciate for heavy trimming tasks. The spool is quite large, so it's great for users who want to avoid frequent replacements.

This line is best suited for those who need heavy-duty trimming power, such as landscapers or homeowners dealing with thick, stubborn weeds and overgrowth. If you have a lightweight or battery-powered trimmer, you might want to check compatibility and consider if a thinner or round line would be easier to handle.

The Oregon Magnum Gatorline flexes well and wears down evenly, reducing the need for frequent restringing.

The Oregon 22-595 Magnum Gatorline Round Trimmer Line offers a good balance of durability and efficiency. With a line diameter of .095 inches, it fits many popular trimmer brands like Echo, Stihl, and Ryobi.

Additionally, the spool contains a notable 1,443 feet of line, ensuring you have plenty of material for multiple uses before needing to restock. This is particularly beneficial for those with larger areas to maintain.

However, while the round shape is very durable and long-lasting, it may not cut as cleanly or precisely as other shapes like the square trimmer line.

If you need a robust and long-lasting trimmer line for a variety of trimming tasks, this product is a solid choice, though it may not be the best for precision trimming needs.

Buying Guide for the Best String Trimmer Lines

Choosing the right string trimmer line is essential for maintaining your lawn and garden efficiently. The right line can make trimming easier, more effective, and can even extend the life of your trimmer. When selecting a string trimmer line, consider the type of vegetation you need to cut, the power of your trimmer, and the frequency of use. Here are some key specifications to help you make the best choice.
Line DiameterThe line diameter is the thickness of the trimmer line. It is important because it determines the cutting power and durability of the line. Thinner lines (around 0.065 to 0.080 inches) are suitable for light-duty tasks like trimming grass and small weeds. Medium lines (0.085 to 0.105 inches) are better for thicker grass and moderate weeds. Heavy-duty lines (0.110 inches and above) are ideal for tough, overgrown areas with thick weeds and brush. Choose a diameter based on the type of vegetation you need to cut and the power of your trimmer.
Line ShapeThe shape of the trimmer line affects its cutting efficiency and durability. Round lines are the most common and are durable, making them suitable for general use. Twisted lines offer better cutting performance and reduced noise, ideal for medium to heavy-duty tasks. Square and star-shaped lines have sharp edges that provide more aggressive cutting, perfect for thick and dense vegetation. Serrated lines have teeth that can cut through tough weeds and brush easily. Select a line shape based on the type of vegetation and the desired cutting performance.
MaterialTrimmer lines are made from various materials, each offering different levels of durability and performance. Nylon is the most common material, known for its flexibility and strength. Reinforced nylon lines, often with added materials like aluminum or polymers, offer increased durability and are suitable for heavy-duty tasks. Some lines are made from copolymer blends, providing a balance of strength and flexibility. Choose a material based on the frequency of use and the toughness of the vegetation you need to trim.
CompatibilityNot all trimmer lines are compatible with every trimmer. It is important to check the manufacturer's recommendations for your specific trimmer model. Using the wrong line can reduce performance and potentially damage your trimmer. Ensure the line diameter and shape are suitable for your trimmer's specifications. Refer to your trimmer's manual or the manufacturer's website for compatibility information.
LengthTrimmer lines come in various lengths, typically measured in feet. The length you need depends on how often you use your trimmer and the size of the area you need to maintain. Longer lines are more economical and reduce the frequency of replacements. However, ensure you have a proper storage solution to keep the line from tangling. Choose a length that matches your usage patterns and storage capabilities.
