Overview

The Milwaukee 2828-20E M18 Brushless String Trimmer is a cordless outdoor power tool built for grass trimming and clearing overgrowth without dragging around fuel, pull cords, or extension cords. This is a string trimmer designed for grass trimming, brush clearing, and routine property maintenance. Model Number: 2828-20E. If you want a bare tool that keeps weight manageable but still has enough cutting power for thicker growth, this is the one Milwaukee built for that gap.

On the job, the big story is the brushless motor. Milwaukee rates it at up to 1.39 HP, and the tool is designed to maintain cutting performance in dense grass with speeds up to 6,200 RPM. That matters because a trimmer that bogs down forces you to slow your pace, make extra passes, and fight the tool. Here, you get the power needed for heavier trimming while still staying in the cordless M18 platform.

The adjustable 14 inch to 16 inch cutting swath is more useful than it looks on paper. Run the narrower setting when you want to stretch runtime or trim more precisely around landscaping and fences. Step up to the wider setting when you need to clear more material per pass. Milwaukee also gives you high and low speed control plus a variable speed trigger, so you are not locked into full output all the time. That kind of control helps when moving from light edging around beds to heavier grass along tree lines.

Milwaukee set this trimmer up to be practical in real use, not just strong on a spec sheet. The Easy Load trimmer head can be loaded in under 30 seconds and holds 25 feet of 0.080 inch line or 20 feet of 0.095 inch line. If you spend time maintaining larger properties, that quick reload setup is a real time saver. It also supports the line sizes most users reach for depending on whether the job is light trimming or thicker material.

At 9.1 lbs, the Milwaukee 2828-20E M18 Brushless String Trimmer keeps weight in a workable range for longer trimming sessions. That lighter setup matters when you are clearing fence lines, trimming around foundations, or working larger yards where fatigue starts to show up in your shoulders and lower back. The layout is straightforward, with a front handle for control and a design aimed at balancing power with day-to-day usability.

As part of the Milwaukee M18 System, this cordless string trimmer is fully compatible with M18 batteries and sits inside a larger platform of over 300 tools. Milwaukee also pairs it with REDLINK Intelligence, which monitors power delivery from the battery to the motor for consistent performance. For anyone already invested in M18, that means one battery system can cover your core jobsite tools and your outdoor cleanup gear.

Who should buy it? This model makes the most sense for contractors, maintenance crews, property managers, and serious homeowners who want cordless convenience but still need legitimate cutting performance. It is especially well suited for users who already run M18 batteries and want a dedicated string trimmer for grass, overgrowth, and brush without stepping into a gas platform. If you are expecting a tool-only package, that is exactly what this is: the trimmer is included, and the battery and charger are sold separately.
