15-Inch vs 17-Inch RYOBI 40V Comparison
Cutting Width
The RYOBI 40V 15-Inch Attachment Capable String Trimmer offers a 15-inch cutting swath. The RYOBI 40V 17-Inch Attachment Capable Trimmer provides a wider 17-inch cutting swath. This two-inch difference means the 17-inch model covers more ground per pass. You will make fewer overlapping passes with the wider unit. This can save time on larger lawns or open areas. The narrower 15-inch model may feel easier to maneuver in tight spaces or around dense landscaping obstacles. Choose the width that matches your yard size and obstacle density.
Motor Type
The RYOBI 40V 17-Inch Attachment Capable Trimmer features a brushless motor. The specifications for the RYOBI 40V 15-Inch Attachment Capable String Trimmer do not list the motor type. Brushless motors generally offer longer life, increased efficiency, and more power than brushed alternatives. This technology helps the 17-inch model deliver more power than a 32cc gas trimmer. It also contributes to the Whisper Series design, which is engineered to be 86% quieter than gas. If motor efficiency and noise reduction are priorities, the 17-inch model has a clear technical advantage.
Runtime
Runtime data is provided for both units when using a 40V 4Ah battery. The RYOBI 40V 15-Inch Attachment Capable String Trimmer offers up to 71 minutes of runtime. The RYOBI 40V 17-Inch Attachment Capable Trimmer provides 45 minutes of runtime under the same conditions. The 15-inch model lasts significantly longer on a single charge. This difference is likely due to the power demands of the brushless motor and the wider cutting deck in the 17-inch model. If you have a large yard and need extended continuous operation without recharging, the 15-inch model is the better choice.
Weight
Both string trimmers weigh exactly 11 pounds. This identical weight makes handling feel similar for both models. You will not experience fatigue differences due to mass. However, the 17-inch model is longer at 72 inches compared to the 15-inch model at 40 inches. The longer shaft of the 17-inch model may shift the balance point further from your body. This could affect comfort during extended use for some users. The 15-inch model has a more compact length, which might feel more manageable in confined spaces despite the same weight.
Noise Level
The RYOBI 40V 17-Inch Attachment Capable Trimmer is part of the Whisper Series. It is engineered to be 86% quieter than gas trimmers. You can cut at any time without disturbing neighbors. The specifications for the RYOBI 40V 15-Inch Attachment Capable String Trimmer do not mention noise levels or a Whisper Series designation. If you live in an area with strict noise ordinances or have close neighbors, the 17-inch model offers a significant advantage. The reduced noise allows for more flexible mowing times. This feature is unique to the 17-inch model in this comparison.
Which RYOBI 40V Trimmer Fits You
Users prioritizing quiet operation for early mornings
The 17-inch Whisper Series model is engineered to be 86% quieter than gas trimmers. This allows you to cut at any time without disturbing neighbors. Its brushless motor and 40V HP technology deliver power comparable to a 32cc gas unit while maintaining low noise levels. Choose this if sound matters as much as cutting width.
Those needing maximum cutting width for large areas
This model features a 17-inch cutting swath, which is two inches wider than the 15-inch alternative. The broader cut helps you cover more ground per pass. Combined with the brushless motor for durability and runtime, it is the better choice if you have larger lawns and want to reduce the number of passes required.
Buyers seeking a lighter, more compact tool
The 15-inch model measures 40 inches in length, making it significantly shorter than the 72-inch 17-inch version. While both weigh 11 pounds, the shorter shaft improves maneuverability in tight spaces. It still offers 40V power and attachment capability, providing a compact option for users who prefer a smaller footprint without sacrificing versatility.
