Honda UMR450 Backpack Brushcutter

The Honda UMR450 Backpack Brushcutter delivers high performance for professional and semi-professional farmers and landscapers working in rugged, hilly terrains. It combines power, comfort, and long-lasting durability to handle tough applications with ease.

Powered by Honda’s GX50 4-stroke engine, it delivers 2.0 hp (1.47 kW) from 47.9 cm³ displacement. The cutting system uses a 3.0 mm nylon line with tap-and-go advancement for faster reloads, and a three-tooth metal blade is included for dense growth and overgrown areas.

Designed for comfort, the UMR450 features a backpack harness with five-point adjustment, soft padding, and balanced handle weight to reduce fatigue during long sessions. An anti-vibration frame and clutch system enhance stability, while a flexible shaft enables access to hard-to-reach areas. The deflector guard width is 380 mm, and the machine’s compact design includes reinforced components for reliable starts and durability.
