A method of moving material, using a first machine, from a first location to a second location, the second location being a dump bed of a second machine. The method includes determining, by a controller of the first machine, a type of a material to be moved, sending, by the controller of the first machine, the material type to a controller of the second machine, determining, by a controller of the second machine, a load distribution on the dump bed based on the material, determining, by the controller of the second machine, a first position of the dump bed at which a first dump should be unloaded from the first machine, and sending, by the controller of the second machine, an identification of the first position to the controller of the first machine.

System and method for moving material

A work machine extending in a fore-aft direction includes a frame, a ground-engaging mechanism, a boom assembly to the frame, and a traction assist apparatus. The ground-engaging mechanism is configured to support the frame on a surface. The traction assist apparatus is coupled to the boom assembly. The traction assist apparatus has an attachment point for securing a tether.

Traction assist apparatus and method for a work machine

A hitch mechanism for a work vehicle configured for operation on slopes. The hitch mechanism couplable to a tether fixed in position up the slope. An arm extends outwardly and upwardly from the work vehicle frame and supports a tether engaging structure couplable to the tether. The arm is mounted to the frame structure beneath the body portion of the work vehicle and extends rearwardly from the frame to support the tether engaging structure rearwardly of the body portion and rearwardly of the ground engaging drive mechanism. The hitch includes a pivot structure coupling the arm to the frame that allows the arm to pivot about a horizontal axis such that the arm is shiftable vertically. A controller receives inputs corresponding to at least one vehicle parameter and is operatively coupled to an actuator for causing the arm to shift in response to changes in the vehicle parameter.

A bogie positioning system and method for a work machine. The bogie positioning system adapted to selectively engage a wheel of a work machine to a ground surface through a bogie assembly wherein the bogie assembly may have a front wheel coupled to a rear wheel through a bogie coupling mechanism. The bogie coupling mechanism comprising a beam with a rotary joint. The rotary joint allowing the front wheel to rotate about a rotary axis relative to the rear wheel. The beam is coupled to a chassis of the work machine with at least one actuator coupled to the beam. A control unit is in communication with the bogie assembly, a user input interface, and a plurality of sensors, generating command signals to actuate the actuator based on the input signals, thereby selectively engaging the front wheel or the rear wheel with the ground surface.

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.

An electronic begin of regulation (EBOR) control system and method is disclosed for a hydraulic motor of a machine having an engine for producing power and a track system for moving. The EBOR system includes a flow source, variable displacement motor, pressure sensor and control unit. The operator sets a pressure setpoint. The flow source generates flow in a loop with the motor. The pressure sensor senses loop working pressure. The control unit adjusts motor displacement based on comparisons between the pressure setpoint and sensed loop working pressure. The flow source can be bidirectional, and different pressure sensors can be used depending on the direction. The pressure setpoint can be varied during operation, and the control unit can adjust the displacement of the motor based on comparisons between the latest pressure setpoint and the loop working pressure sensed by the appropriate pressure sensor.

A controlled lean system for a tree feller-buncher includes a sensor configured to measure an orientation of a boom coupled to the tree feller-buncher, and a felling head operably connected to the boom. A controller is operable to detect a cut tree carried by the felling head and to estimate a quantity of tree lean needed to reduce torsional load during rotation of the boom while carrying the cut tree based at least in part on the measured orientation of the boom.

Felled tree lean control system and method

A drift control method for a machine that includes a controller, a cutting tool, a motor having a motor shaft for driving a machine function, a control valve, and an operator control for commanding a machine function. The drift control method includes sensing a neutral position of the operator control, and when in the neutral position, further storing a first position of the motor shaft or cutting tool in the controller, detecting a change in position of the motor shaft or cutting tool with a sensor, determining a direction as a function of the change in position, and hydraulically controlling the motor shaft or cutting tool to the first position.

Drift control system of a work machine and method thereof

The present disclosure provides a control system of a powered machine. The control system includes a hydraulic motor configured to drive a track system of the machine. The motor is operable with a variable displacement. A control valve is fluidly coupled to the motor. In addition, the control system includes a controller and an electro-hydraulic valve disposed in electrical communication with the controller and fluid communication with the control valve. The electro-hydraulic valve receives a signal from the controller, and based on the signal, the electro-hydraulic valve hydraulically varies the start of control pressure of the motor.
