HONDA UMR450 Petrol Backpack Brushcutter

When the terrain is steep, the vegetation is dense, and the hours are long, you need a machine that won’t hold you back. The Honda UMR450 Petrol Backpack Brushcutter, available at Ron Smith & Co., is built for exactly that. Designed for professionals and serious landowners alike, this rugged and reliable tool offers powerful cutting performance combined with unmatched comfort—perfect for clearing demanding ground day after day.

This model stands out with its backpack-mounted GX50 4-stroke engine, providing exceptional balance and reduced fatigue, even on long shifts in tough conditions. Whether you’re clearing slopes, ditches, or overgrown land, the UMR450 gives you the confidence to take on heavy workloads without compromise.

GX50 4-Stroke Engine: Fuel-Efficient, Powerful, and Easy to Use

At the core of the UMR450 is Honda’s proven GX50 engine, delivering 2.0 hp (1.47 kW) of smooth, consistent power. This 47.9 cc 4-stroke unit offers several advantages over traditional 2-stroke engines: there’s no fuel mixing, it runs cleaner, and it’s impressively quiet and fuel-efficient—ideal for extended use in both urban and rural settings.

Pair that with Honda’s legendary build quality, and you’ve got a professional-grade brushcutter ready to perform in the harshest environments.

Heavy-Duty Cutting with Upgraded Nylon Line

Tough jobs require serious cutting performance, and Honda delivers with a 3.0 mm nylon line upgrade—increased from 2.7 mm in previous models. This boost means faster, more efficient clearing, whether you’re managing overgrowth on farmland or tackling stubborn brush in woodland areas.

The brushcutter’s wide 380 mm guard offers excellent debris protection while supporting a generous cutting swathe, so you get through jobs quicker without compromising on safety.

Ergonomic Backpack Harness for All-Day Comfort

Unlike traditional brushcutters, the UMR450 features a comfortable backpack harness, shifting the weight of the engine away from your arms and onto your back for better posture and reduced strain. This design allows for greater mobility and less fatigue, especially on uneven ground and during long work sessions.

The flexible shaft and extended reach make it easy to access awkward or sloped areas without awkward angles or excess arm fatigue—ideal for landscaping professionals, contractors, and estate managers.

Engineered for Professional Durability

From the reinforced 26 mm shaft to the robust 7 mm drive shaft, every part of the UMR450 is built to last. It’s a machine designed to endure heavy-duty workloads, with a dry weight of 11.8 kg (12.4 kg wet) that strikes the right balance between rugged stability and manageable handling.

Whether you’re using it day in, day out, or for seasonal clearance, this is a tool you can trust to keep up with you.

Peace of Mind with Honda Warranty

Your investment is protected with a 5-year domestic warranty and 1-year commercial warranty direct from Honda, giving you confidence that your brushcutter is covered for the long haul—whether you’re using it at home or on the job.

Serious Performance for Serious Work

The Honda UMR450 Petrol Backpack Brushcutter is more than just a tool—it’s a reliable partner for professionals working in tough environments. Whether you’re maintaining estates, clearing brambles, or working on steep ground, it provides the power, comfort, and endurance you need.
