THE RIGHT AMOUNT OF POWER
Powered by Honda's famous 25cc 4-Stroke Engine, this VersaTool powerhead already comes standard on most of Honda's range of handheld power equipment
Suitable for the residential user, this powerhead delivers the 'starts-first-time every-time' reliability that Honda is known for, and offers superior performance no matter what attachment is connected.
A lightweight and ergonomic design, paired with the power that comes standard with a Honda, results in a power source that you can rely on day in, day out.
ADVANCED TECHNOLOGY
The world's lightest OHC engine, the Honda Mini 4-stroke engine requires no fuel/oil mixing, and runs at approximately half the operating cost of comparable 2-stroke engines.
A full 360° "any-side-up" operation means you can use and store the UMC425 in any position, and take advantage of the exclusive rotary-slinger lubrication system.
The carburetor is equipped with an accelerator pump for fast, easy acceleration, and an efficient port configuration and large diameter valves maximise power output.
