About the HONDA UMK 425 UE Petrol Brushcutter
Tackle the areas your mower can’t reach with the Honda UMK 425 UE Petrol Brushcutter. Brimming with useful features, this premium brushcutter comes with a powerful engine and ergonomic design to help you clear areas of thick vegetation quickly and efficiently.
The Honda UMK 425 UE Strimmer and Brushcutter
The Honda Brush Cutter UMK425U is fitted with a compact but robust 4-stroke OHC GX25T engine, with a reliable recoil start, 25 cc displacement and net power of 0.72 kW (0.97 hp). Optimised to consistently deliver high performance with low emissions, it has a sound power level of 109 dB(A).
Featuring a lightweight flywheel, heavy-duty transmission head and straight shaft, the Honda UMK 425 UE 4 Stroke Brush Cutter comes with two cutting attachments: a 2-line tap-and-go nylon head and durable 3-tooth blade, which is expertly engineered to cut through tough vegetation like a knife through butter. IPX4 certified, this petrol brushcutter is suitable for use in adverse weather conditions.
Key Measurements

The UMK425’s High-Specification Components
Far higher quality than those found on most brushcutters, the UMK425’s six-splined transmission drive shaft and advanced, non-contact bearings are identical to the high-spec components used by NASA. They are exceptionally durable, excel at high speeds, and ensure the engine operates quietly.
Fitted with an Anti-Vibration Clutch
The Honda UMK425U Brush Cutter features an anti-vibration centrifugal clutch, making it very comfortable to handle and reducing operator fatigue.
Controlling the Honda 425 Brushcutter
Providing excellent balance and enhanced user comfort, the Honda UMK 425 UE Petrol Brushcutter is designed with bike-style handlebars. All of the key functions are located on one of these handles, so the controls can be operated single handedly.
And with the benefit of a comfort double shoulder harness too, you’ll find it easy to operate the Honda UMK425 Bike Handle in a smooth, flowing action. (This harness is simple to adjust for increased safety and ease of use.)
Single Tap Trimming
Thanks to the UMK425 Honda Brush Cutter’s semi-automatic design, you can release an additional line with just one tap.
So, when you’re in the middle of removing tough vegetation, there’s no need for any unnecessary interruptions to your work.

Maintain Your Honda Products Properly
To keep your Honda petrol machinery running at its best, use standard pump fuels such as SP95, SP98, or SP95-E10.
While Honda doesn’t supply alkylate fuel, its use is permitted.
It’s important to always add a fuel stabiliser, especially if you’re storing fuel for more than a few weeks, as this helps prevent engine issues and keeps the fuel fresh.
Fuel should be stored in small amounts (no more than 5 litres) in a sealed container, away from heat and sunlight. Use within one month unless treated with a stabiliser.
At the end of the season—or if the machine won’t be used for a while—it’s recommended to drain the fuel tank and follow the storage advice in the user manual.

Excellent service from Garden machinery direct , good delivery company used , product is excellent so far .
David Burns. –
Extremely good strimmer/brush cutter. The 4 stroke engine is quiet, starts totally reliably and is sufficiently powerful. Easy to service, good harness and control bars make long work sessions possible without serious fatigue. Having used various 2 stroke strimmers/cutters in the past, this is very much better option.
