Abstract
A bush cutting apparatus has a first rotational shaft mounted for undergoing rotation and a cutter blade connected to the first rotational shaft for rotation therewith. A clutch mechanism has a rotational member, at least one clutch moving member mounted on the rotational member for undergoing movement along a radial direction of the rotational member, a clutch drum mounted on the first rotational shaft for sliding movement therealong to engage the clutch moving member, and a clutch resilient member for biasing the clutch moving member toward an axial centerline of the rotational member. A brake mechanism has a brake shoe formed at an end portion of the clutch drum, a brake pad disposed opposite to and confronting the brake shoe, and a braking resilient member for biasing the brake shoe into pressure contact with the brake pad. A drive source has a second rotational shaft for selectively rotating the rotational member of the clutch mechanism at rotational speeds higher or lower than a preselected rotational speed. The second rotational shaft is axially spaced from and operatively connected to the first rotational shaft via the clutch mechanism and the brake mechanism for rotationally driving the first rotational shaft.
