SRM-301TES/U

Commercial-grade battery brushcutter with Ergo-Pro Flex harness and heavy-duty blade for maximum productivity and comfort.

Built on the same powerful platform as the DSRM-3500U, the ECHO DSRM-3500-UP combines exceptional cutting performance with enhanced operator comfort and versatility. Delivering an impressive 1.4 kW mechanical output, equivalent to a 35cc petrol engine, it powers through heavy grass, dense vegetation and demanding professional tasks with ease. What sets the DSRM-3500-UP apart is the inclusion of the premium Ergo-Pro Flex harness, designed to distribute weight more effectively and reduce operator fatigue during extended working hours. Combined with the ergonomic U-handle design and advanced anti-vibration system, it provides outstanding comfort, balance and control even in the toughest conditions. The DSRM-3500-UP also features a dedicated heavy-duty cutting blade, offering increased cutting efficiency and durability when tackling thicker vegetation and more demanding clearing applications. At just 5.3 kg (without battery, cutter or harness), it delivers the perfect balance of high-performance cutting power, professional comfort and long-lasting reliability.

FAQ

See the whole FAQ

Always adjust the harness before using your brushcutter. You may be wearing something different from last time you used the tool. Getting the right fit will increase comfort and lower stress on your body - increasing efficiency and reducing fatigue.

Store nylon line in a cool area away from direct sun light. Before use it's a good idea to keep the line in a bucket of water for at least 24 hours. This keeps the line flexible and reduces the need for refilling as the line wont break as easily - saving you time and increasing your efficiency.

Trimmers and brushcutters are used to clear areas that your mower can't get to or lacks the power for. If you use the correct technique when trimming you will increase your productivity and reduce fatigue. The trimmer head should be just above the ground at a slight angle. Since it's the end of the line that does most of the work, ensure your line is always close to its full length. The cutter on the shield will automatically ensure any excess length is removed. When cutting, using a sweeping motion from right to left, will keep consistency and also push the clippings into an orderly pile. Between cuts, when sweeping the tool, it's good practice to release the throttle to idling.
