ABSTRACT:
A tree vibrator (8) includes an electric motor (14) disposed within a housing (15) mounted on tree (10) by band clamp (18). An adjustable eccentric weight assembly (24) is mounted on the rotary output shaft (26) of motor (14) to impart vibrations of a desired intensity on tree (10). Motor (14) is powered by battery assembly (49) through an intermediate electronic power control circuit assembly (56) to intermittently energize motor (14), significantly extending the useful life of batteries (50) of assembly (49).
