HONDA UMR450 Petrol Backpack Brushcutter

If you need a brushcutter that delivers serious performance, comfort, and reliability—no matter how steep, overgrown, or remote the job site—the Honda UMR450 Petrol Backpack Brushcutter is made for you. Designed with professionals and semi-professionals in mind, this high-performance machine is built to thrive where other tools struggle, making light work of the most demanding brush-clearing tasks.

Whether you’re tackling rugged hillsides, maintaining overgrown farmland, or working long hours in challenging conditions, the UMR450 offers the power, durability, and ergonomic design needed to get the job done—day in, day out.

Engineered for Demanding Work

At the heart of the Honda UMR450 lies the trusted GX50 4-stroke engine—a reliable and efficient powerplant that delivers 2.0 horsepower (1.47 kW) of high-output performance. With a displacement of 47.9 cm³, this engine provides smooth, consistent power that’s ideal for intensive brushcutting over long periods.

Unlike traditional 2-stroke engines, the GX50 runs on straight unleaded petrol—no need to mix oil and fuel—which simplifies refuelling and helps reduce both maintenance time and emissions. It’s also renowned for its low noise levels and excellent fuel economy, making it a top choice for professional use in noise-sensitive or remote areas.

Built for Power and Precision

The UMR450 doesn’t just offer power—it’s designed to deliver that power precisely where you need it. Equipped with an upgraded 3.0 mm nylon cutting line (increased from the previous 2.7 mm), this brushcutter cuts through dense grass and undergrowth with ease, offering a faster, cleaner finish even in tough conditions.

The cutting system is supported by a 26 mm diameter shaft and a robust 7 mm drive shaft, ensuring durability and optimal power transfer from engine to cutting head. With a pipe length of 1405 mm, you also benefit from extended reach—helping you cover more ground without strain.

The 380 mm deflector guard provides essential protection while allowing for a wide cutting swath, increasing efficiency without compromising safety.

Superior Comfort with Backpack Design

One of the standout features of the Honda UMR450 is its backpack-mounted engine, a design that completely transforms the way brushcutting feels—especially on long or challenging jobs.

Instead of carrying the engine on the shaft or directly in your hands, the UMR450 distributes the weight evenly across your shoulders and back using a comfortable, ergonomic harness system. This helps reduce fatigue, especially when working for extended periods or navigating steep, uneven terrain.

The flexible shaft and backpack design also give you greater freedom of movement, making it easier to access hard-to-reach areas and operate the tool for hours at a time with less physical strain. For professionals working in woodland areas, on embankments, or around large properties, this ergonomic approach can make a world of difference.

Built to Last

As you’d expect from Honda, the UMR450 has been designed with longevity in mind. Its high-quality materials, precision engineering, and robust construction mean it’s built to withstand regular use in professional environments.

From the reinforced drive shaft to the wear-resistant guard and heavy-duty engine casing, every component is made to endure the rigours of commercial or semi-commercial brushcutting. And thanks to the 4-stroke engine’s lower operating temperature and smoother combustion cycle, you’ll experience less wear and tear over time compared to many 2-stroke models.

With a dry weight of 11.8 kg and a wet weight of 12.4 kg, the machine remains manageable for most users while offering the stability and power required for tough work.

Peace of Mind with Honda Warranty

To back up its outstanding performance and reliability, the Honda UMR450 comes with a 5-year warranty for domestic use and a 1-year warranty for commercial use. That’s a testament to Honda’s confidence in the quality and durability of their machines—and reassurance for you that your investment is protected for the long term.
