Who it fits

Key specs for this trimmer

82V Voltage

This voltage rating indicates the electrical potential driving the motor. Higher voltage generally means more torque and cutting power compared to lower voltage tools. You can expect this tool to handle thicker weeds and brush with less strain. It is comparable to mid-range gas trimmers, offering consistent performance without the maintenance of an engine.

Brushless Motor

A brushless motor uses electronic commutation instead of physical brushes. This design reduces friction and heat, leading to longer motor life and better energy efficiency. You will get more runtime from your battery and less maintenance over time. It is a key feature to look for when comparing cordless options for durability.

16 in Cutting Swath

This measurement defines the width of the cutting path. A 16-inch swath allows you to clear grass and weeds in wider passes. It balances maneuverability around obstacles with speed for larger areas. When shopping for cordless mowers, wider decks cover ground faster, but this trimmer width is ideal for precision edging and trimming.

2.5 Ah Battery Capacity

Amp-hours measure the energy storage capacity of the battery. A 2.5 Ah rating provides a moderate runtime for typical yard tasks. You can expect to trim up to 2.5 miles on a single charge. This capacity suits small to medium yards. Larger capacities offer longer runtime but add weight, so choose based on your yard size.

Load N' Go Trimmer Head

This is a specific line feed system that holds up to 34 feet of .095-inch trimmer line. It simplifies reloading by allowing you to push a button to advance the line. You spend less time refilling line and more time trimming. This feature is convenient for users who want to avoid the hassle of manual line insertion.

Design and build details

The listing states the Greenworks 82ST151 uses durable magnesium construction. This material choice helps keep the overall weight at 22 pounds. You get a 1.1-inch diameter shaft that provides a greater cutting arc. This wider shaft likely improves stability when you are trimming near obstacles or uneven terrain. The tool measures 72.8 inches in length. The height is 5 inches, and the width is 8.66 inches. These dimensions suggest a balanced layout for standard use. You can hold it comfortably for extended periods without excessive fatigue. The finish is green, matching the brand's typical aesthetic. It does not appear to have complex housing or unnecessary bulk.

Controls are straightforward. You operate it with a variable speed trigger. This allows you to adjust power output based on the density of the vegetation. A 2-speed switch is also included for ultimate control. You can select the appropriate speed for light grass or thicker weeds. The Load N' Go trimmer head holds up to 34 feet of .095-inch line. This system simplifies line reloading. You do not need to stop and manually feed line during work. The design prioritizes efficiency and ease of use. You can focus on trimming rather than managing equipment. The magnesium body and simple controls make this tool suitable for regular yard maintenance. It fits users who want reliable performance without complicated features. According to the listing, the build supports all-day use.

Setup and everyday use

Setting up the Greenworks 82ST151 is straightforward. You insert the included 82V 2.5Ah battery into the tool. The listing notes this battery holds 180 Watt Hours of energy. This power source drives the brushless motor. You do not need to mix fuel or check oil levels. The tool is ready for operation once the battery clicks into place.

Daily use begins with adjusting the variable speed trigger. You can select from two speed settings using the dedicated switch. This feature gives you control over the cutting speed. The motor delivers up to 5,700 RPM. This consistent speed helps maintain performance as you trim.

The 16-inch cutting swath covers a moderate area per pass. You can trim up to 2.5 miles on a single charge. This runtime depends on your workload and trigger usage. The Load N' Go trimmer head holds 34 feet of .095-inch line. You can reload the line without tools. This system simplifies maintenance during long sessions.

Ergonomics are supported by the 1.1-inch diameter shaft. This wider shaft improves stability. The magnesium construction keeps the weight at 22 pounds. This balance aids in all-day use. Be aware that this 82V model is not compatible with Greenworks 80V products. You must use the 82V battery system. The tool’s length is 72.8 inches. This height allows for comfortable standing operation. You handle thick weeds with less strain due to the direct drive motor.

Check compatibility and upkeep

This string trimmer does not replace a lawn mower. You still need a mower for the main grass area. The Greenworks 82ST151 handles edges and tough weeds around obstacles. Check your existing battery ecosystem carefully. The listing warns it is not compatible with Greenworks 80V products. If you already own 80V tools, this 82V model requires a new battery and charger. The included 2.5Ah battery provides up to 2.5 miles of trimming. You may want a higher capacity battery for larger yards. Maintenance is minimal. Clean the trimmer head after use. Keep the 16-inch cutting path clear of debris. This tool fits best in a mixed setup. Use a cordless mower for flat grass. Use this trimmer for precision work. It complements other cordless options well. Ensure your workspace allows for safe operation. The brushless motor offers consistent speed. This reduces wear on internal components over time.

Check before you buy

• Verify your existing Greenworks battery is 82V, not 80V.
• Confirm you have a separate lawn mower for flat areas.
• Check if the 2.5Ah battery meets your yard size needs.
• Ensure you have space for safe trimming operations.
