Engines
The 128R’s two-stroke is simple and starts easily thanks to Smart Start, but every tank needs mixing (fuel ratio chart). Honda’s GX25 four-stroke runs on petrol from the pump, is 360° inclinable, and has a reputation for easy running; the trade-off is engine oil to check.
Handles and kit
The two are set up differently. The Husqvarna’s bullhorn handle and double harness suit long sessions across open grass; its grass blade handles coarse grass and weeds. The Honda’s D-loop handle is nimble around obstacles, and its 3-tooth blade takes on light woody growth — keep blade work light with a loop handle.

- You do long sessions on open ground and want a harness
- Easy starting matters and fuel mixing doesn’t bother you
Choose the Honda UMK 425 if…
- You want to skip fuel mixing
- You trim around obstacles and like a loop handle
Which should you buy?
For open ground and long sessions, the 128R. For mix-free, nimble trimming, the UMK 425. Both are sold mainly through dealers.
