ONCEPT AND MAIN APPLICATIONS
These four 25.4mL Petrol Brushcutters have been developed as
the successor models of
equipped with 24.5mL 4-stroke engine.
Their main feature is the multi-position engine lubrication system.
This unique system enables the engine to be inclined to any angle
even during continuous operation with no emission of white smoke
and smell of burning engine oil for wider application range of the
brushcutters.
EM2651UH and EM2651LH additionally feature rapid start.
EM2650UH and EM2651UH are Bike handle models.
EM2650LH and EM2651LH are Loop handle models.
