From tackling overgrown grass to precision edging, we’ve tested this trimmer in various conditions to bring you an honest assessment of its performance, durability, and value.

POWERSTATE™ Brushless Motor: Commercial-Grade Performance

The heart of this string trimmer is Milwaukee’s proprietary POWERSTATE™ brushless motor. During our testing, we were immediately impressed by the motor’s ability to maintain consistent power, even when cutting through thick, wet grass and dense weeds. Unlike many battery-powered trimmers that bog down under load, the 2825-21ST maintained its cutting speed through the toughest conditions.

Performance That Rivals Gas-Powered Models

One of our biggest questions going into this review was whether the Milwaukee M18 FUEL String Trimmer could truly replace a gas-powered model. After extensive testing, our answer is a resounding yes. The power delivery is exceptional, with none of the typical drawbacks associated with battery-powered yard tools.

During our tests, we tackled:

– Overgrown field grass reaching 2+ feet high
– Thick brush and weeds along fence lines
– Precision edging around delicate garden beds
– Wet conditions after morning dew and light rain

In each scenario, the Milwaukee 2825-21ST performed impressively, with no stalling or significant power reduction. The variable speed trigger allowed us to conserve battery when working on lighter tasks and ramp up the power when needed for tougher vegetation.

Battery Life and Charging: A Full Day’s Work

The included 8.0Ah battery provided approximately 60 minutes of continuous use on the lower speed setting, which aligned with Milwaukee’s claims. On the higher speed setting, we still managed about 40 minutes of runtime—more than sufficient for most residential properties.

The rapid charger included in the kit is a game-changer. During our testing, we were able to recharge the depleted battery to 80% in about 45 minutes, making it possible to work continuously with a second battery if needed.

Ergonomics and Usability: Designed for Extended Use

The Milwaukee M18 FUEL String Trimmer 2825-21ST kit impressed us with its thoughtful design elements that reduce fatigue during extended use:

– **Balanced Weight Distribution**: The battery position creates excellent balance, reducing arm strain
– **Adjustable Front Handle**: We could customize the positioning for optimal comfort
– **Vibration Dampening**: Significantly less vibration than gas-powered alternatives
– **Quick-Adjust Shaft Length**: Accommodates users of different heights

At 8.9 pounds with the battery installed, the trimmer isn’t the lightest on the market, but the superior balance makes it feel lighter during actual use. We spent over three hours (with breaks for battery changes) trimming a large property and experienced minimal fatigue.

Line Feed System: Simple and Reliable

The bump feed mechanism worked flawlessly during our testing. A light tap on the ground released the perfect amount of line, and we appreciated that the trimmer uses standard 0.080″ line that’s readily available. The line rarely tangled or broke during our testing, even when we encountered hidden rocks and edging.

Durability and Build Quality: Professional-Grade Construction

Milwaukee tools are known for their durability, and the 2825-21ST string trimmer is no exception. After several weeks of intensive use, we observed:

– No visible wear on the cutting head components
– Consistent performance of the bump feed system
– Durable shaft and handle connections with no loosening
– Robust guards that deflected debris effectively

The weather-resistant construction proved valuable during our testing period, which included some light rain showers. The trimmer performed reliably in damp conditions, though we’d still recommend storing it in a dry location.

This versatility makes the 2825-21ST an excellent value proposition for homeowners who want to maximize their investment in battery-powered outdoor tools.
