Abstract: A vegetation clearing device relating to the clearing of small-caliper vegetation, the vegetation clearing device having a grapple configured to releasably grapple the small-caliper vegetation, a cutter configured to cut the small-caliper vegetation engaged within the grapple, a support frame configured to support the grapple and the cutter, a coupler configured to removably couple the support frame to a working arm of a tractor, the coupler having a first pivot enabling pivoting of the support frame about a first rotational axis and a second pivot enabling pivoting of the support frame about a second rotational axis, the second rotational axis being non-parallel with the first rotational axis, a power-driven grapple actuator configured to actuate the releasable grappling by the grapple, and a power-driven rotator configured to rotate the support frame about the second rotational axis.
