A cutting tooth system for a disk of a disk-saw felling head. The disk defines a receiving portion and an axis of rotation. The cutting tooth system comprises at least one cutting tooth. The cutting tooth comprises a first portion defining a first protrusion and a second protrusion. The first portion is configured to be received in the receiving portion for rotation with the disk. A second portion defines a chip removal path and a cutting edge adjacent the chip removal path. A first retaining device is configured to couple to the disk to secure the first protrusion in the receiving portion. A second retaining device is configured to couple to the disk to secure the second protrusion in the receiving portion.

A control system receives information indicative of characteristics of tree bundles that are felled at various locations in a forestry site. The control system receives information indicative of characteristics of the various machines that can be deployed at the forestry site. It includes a solution generation system that generates solutions indicative of which equipment should be deployed, to different locations in the forestry site, and particular routes over which the deployment is to occur. Control signals can be generated to control the equipment based on the generated solutions.

A tree processing system may include a tree processing head and a controller. The tree processing head may include a header frame, a motor, a saw, an arm, and a sensor. The saw is used to cut a tree when the saw is driven by the motor. The saw engages with the tree from a first position and to a second position. The first position and the second position define a cutting zone therebetween. The sensor is used to detect a saw operation speed or current. The controller is coupled to the sensor and configured to determine whether the second position is reached based upon an increase of the saw operation speed or current detected by the sensor. When the second position is reached, the controller transmits a resting signal to the tree processing head to perform a resting operation.

A work vehicle includes a pin connected to a stick boom at a location remote from a hoist boom. The pin has an envelope throughout which the pin is moveable by the hoist boom and the stick boom. A controller can receive a first signal from a hoist boom sensor, receive a second signal from a stick boom sensor, and receive input from a user interface. The controller can inhibit movement of the pin to at least one portion of the envelope, thereby permitting movement throughout a movement envelope, the movement envelope being smaller than the envelope. The controller can operate in a first operation mode when the pin is spaced from a perimeter of the movement envelope and can operate in a second operation mode when the pin is proximate the perimeter of the movement envelope.

The improved thinning or clearcut head is configured a tree harvesting vehicle supported by a plurality of wheels and tires. The improved thinning or clearcut head is adapted for use in cutting down a target tree. The improved thinning or clearcut head comprises a tree harvesting vehicle and a lateral pivot apparatus. The tree harvesting vehicle comprises a harvest vehicle and a cutting tool. The lateral pivot apparatus attaches the cutting tool to the harvest vehicle such that the cutting tool rotates around a lateral axis of rotation that is parallel to the center axis of the target tree. The improved thinning or clearcut head aligns the cutting tool with the target tree such that the alignment axis between the clamping arms of the cutting tool and the target tree is offset from primary sense of direction of the harvest vehicle.

A forestry machine configured to cut timber, where the forestry machine comprises a felling head including a support frame having an accumulation pocket, an accumulating arm, and a harvest arm. The forestry machine further comprises a stator having coils thereon adapted to produce a time varying stator magnetic field, a rotor having at least either a set of slots or a set of permanent magnets mounted thereon facing the stator and adapted to produce a radially directed flux or an axially directed flux. The rotor is rotatably coupled to the stator in axial alignment therewith by the time varying stator magnetic field. The rotor comprises a saw blade.
