ABSTRACT:
A pruning boom for pruning or trimming trees, bushes, shrubs and the like. A plurality of circular saw blades are rotatably mounted on a saw carrying member. Each saw blade is positioned for rotation in a spatial plane which intersects the spatial plane containing the surface of the saw carrying member located immediately behind the saw blades at an identical non-perpendicular angle. In the preferred embodiment of the present invention, one pruning boom is mounted on each side of the front-end of an agricultural vehicle to construct a machine for pruning parallel rows of citrus trees. During such pruning operations, the angular relationship between the rotating saw blades and the saw carrying member prevents newly cut branches and limbs from wedging in the space between the saw blades and the saw carrying member. The saw blades are overlapped at their peripheries with the uppermost portion of each saw blade positioned behind the lowermost portion of the adjacent saw blade above it on the saw carrying member.
