A cutting attachment includes a mounting bracket and a cutting deck. The mounting bracket is configured to couple to at least one hydraulic arm of a tractor or excavator. The cutting deck is coupled to the mounting bracket. The cutting deck includes an inner surface, an outer surface, a motor coupled to the inner surface, a blade carrier coupled to the outer surface and rotatable by the motor, and at least one blade coupled to the blade carrier.

An implement system for a machine. The implement system includes a boom, an implement, a roller assembly and a carriage. The boom has a telescopic structure and a first end. The implement is coupled to the first end of the boom. The roller assembly is configured to be coupled to the machine. The carriage is engaged with the roller assembly and is coupled to the boom. The carriage is configured to move linearly along a longitudinal axis of the machine between a first position and a second position.

A field-configurable apparatus for different aerial applications is provided. The field-configurable apparatus attaches to an aerial boom on a mobile carrier. The apparatus can perform rapid semi-precise cutting of vegetation. Additionally, the apparatus can perform more precise trimming of one or more areas (e.g., limbs) and optionally use a limb clamp to prevent cut limbs/vegetation from arbitrarily falling on objects below the cutting area. Still further, the apparatus can have a grapple or similar device attached to the end of the boom for use in relocating debris or for loading debris. Other industrial applications are also possible (e.g., commercial water blasting, deicing of planes, etc.). In each configuration, the apparatus comprises one or more rotatable or pivoting couplings to allow for rotation about one or more axis and therefore allow precise manipulation of an aerial tool assembly from an operator in the vehicle or on the ground.

A forestry harvester for delimbing a tree with an angular upper cutter and side cutters while advancing the tree by feed rollers, wherein when the feeding of the tree is stopped due to being incapable of cutting the limbs off, the angle-shaped upper cutter and the side cutters are moved relative to the tree with rotation of the feed rollers stopped to cut off the limbs of the tree therewith.

The forestry harvester comprises a feed unit (1 or 100) including a pair of left-hand and right-hand clamp arms (8, 9 or 108, 109) and feed means (20 or 120), a chain saw box (22a) having a power chain saw (22), a delimbing unit (2) including an angle-shaped upper cutter (52) and a pair of cutter arms (26, 26) each having a side cutter (25), guide mechanism for guiding the delimbing unit for forward and rearward movement of the delimbing unit relative to the feed unit, and a hydraulic cylinder (47) actuated to move the delimbing unit (2) toward and away from the feed unit (1 or 100).

A mobile apparatus with a fluid pressure-operated implement mounted at a distal end of a boom includes a connection apparatus for selectively rotating the implement about an actuator axis at the distal end of the boom. The connection apparatus includes a rotary actuator and a pressurized fluid circuit for delivery of pressurized fluid through the rotary actuator to the implement. The pressurized fluid circuit includes channels establishing a fluidic connection axially through the rotating shaft of the rotary actuator. The pressurized fluid circuit facilitates passage of pressurized fluid through an internal, protected environment to the implement.
