Abstract

The small tiller “Komame” has been used for various agricultural tasks ranging from cultivation of small vegetable gardens to more serious vegetable growing processes for the last 20 years. This tiller has gone through a full model change this year to become the “New Komame F220.” The New Komame’s engine now has a rounded full cover that helps even novice users feel at ease. Reduced emissions from its OHV engine and 5.5dB (A) less noise (obtained by utilizing a resin cam and larger muffler capacity) enable the “New Komame F220” to meet the requirements of both the CARB and EPA emission regulations as well as the EU Noise Directive. The machine weighs 9% less due to the smaller engine and resin parts. Changes to the tilling blades by simulation analysis have provided simple handling together with ample performance. The force required for the recoil starter has been cut by 30% through decreasing engine displacement. The force required to operate the clutch lever has also been reduced by 20% through the use of a different shoe clutch lining material. The new easier to use F220 delivers useful functions and high performance.
