About the MOUNTFIELD MTR 20 Li Cordless Grass Trimmer (Kit)
Efficient Trimming for Smaller Gardens
The Mountfield MTR 20 Li is a lightweight, battery-powered grass trimmer designed for smaller domestic gardens. It delivers excellent cutting power without the noise, fumes, or maintenance of petrol machines. With cordless convenience and simple controls, it’s ideal for quick garden tidy-ups and hard-to-reach areas your mower might miss. You can easily finish lawn edges, borders, and around trees using one compact tool.
Cordless Freedom with Reliable Battery Power
This trimmer is powered by a 20V 2Ah lithium-ion battery from STIGA’s trusted ePower range. With one charge, you can enjoy up to 20 minutes of continuous trimming, enough to tackle small lawns. The battery is lightweight and charges quickly, offering convenience with no cords or fuel needed. Just click the battery into place and start trimming right away with zero fuss.
Part of the Flexible Freedom 100 Range
One of the MTR 20 Li’s key benefits is compatibility with Mountfield’s Freedom 100 series. Every tool in the range uses the same 20V battery and charger. This means less storage space, lower costs, and easier access to a complete garden tool system. You can expand your tool collection without needing multiple batteries or chargers. It’s a practical solution for gardeners looking for a simple setup.
Designed for Comfort and Ease of Use
The MTR 20 Li has been built with user comfort in mind, making it suitable for gardeners of all strengths. It includes a telescopic shaft that adjusts across six positions for an ideal working height. The soft grip handle feels comfortable even during longer sessions, reducing hand fatigue. A pivoting head allows for easier trimming at tricky angles, such as under benches or along borders.
Efficient Cutting Performance
The machine’s cutting width is 25 cm, ideal for neat edging and finishing off awkward areas. It features a modern 150W brushed motor, delivering a top speed of 8000 rpm for consistent performance. The automatic single-line feed ensures smooth, uninterrupted cutting without manual adjustments. This combination of features makes it a dependable option for light, regular garden maintenance.
Lightweight and Quiet for Hassle-Free Use
Weighing very little, the MTR 20 Li is one of the most manageable trimmers in its class. It’s particularly well-suited for users who prefer lighter equipment or don’t want the hassle of cables and petrol. The quiet operation makes it more pleasant to use, especially in residential areas or at times when noise must be kept to a minimum.
Great Value with Everything Included
The Mountfield MTR 20 Li comes with a battery and standard charger, making it excellent value straight out of the box. There’s no need to buy extras to get started. It’s affordable, convenient, and easy to use, giving you professional results in a lightweight package. For smaller gardens and lighter maintenance, this trimmer is a smart, reliable choice.
Comes with a 2 year conditional warranty.
