Honda's UMK Series Trimmers Are Truly Top Of The Line
Lawn-care
professionals are always looking for equipment that works as hard as they
do. Equipment that is dependable, durable and powerful. And when it comes
to string trimmers, they should look no further than the new line of hard-working
Honda UMK Series string trimmers.
A leader in engine technology, Honda has taken its latest accomplishment, the Mini 4-Stroke engines, and crated a line of trimmers that is second to none. Powered by the only 360º inclinable 4-stroke engine available today, the new Honda trimmers deliver smooth, dependable power and unsurpassed fuel efficiency. They require no special gas/oil mixtures so there's no chance for improperly mixed fuels. And they're remarkably quiet, virtually smokeless and environmentally friendly.
But there's much, much more. The engine drives a multibearing supported hardened steel shaft housed in an aluminum tube through a centrifugal clutch with final drive through bevel gears. The toughness of this system means any of the new Honda trimmers can power both a steel blade or trimmer head.
For comfort and ease, Honda offers loop handles on both engine sizes, or the standard U-shaped handles on the UMK431UNBA model for increased leverage and precise control. Electronic ignition and primer systems deliver quick, reliable starts, and trigger throttle and finger-tip mounted engine stop switch provide safe and convenient control. Plus, an advanced anti-vibration system ensures controls are isolated from engine vibration.
So if you're looking for the best trimmer for any job, look no further than the new Honda UMK Series. By combining all the features you need with a name that means quality, this new line of trimmers is truly top of the line.
