Measurement of Kickback Reaction Force of a Brush Cutter

KASHIMA Jun and SASAKI Tatsuya

Abstract
　　The kickback reaction force of a brush cutter was computed from the rotational acceleration at the time of kickback occurrence. The results showed a maximum reaction force of about 4N, and it was conjectured that the kickback reaction force depends on the engine power and the impact conditions of cutting blade with obstacles.

Key words：brush cutter, kickback, rotational acceleration, reaction force
