20090095375 | TREE COUNTER FOR A SAW HEAD IN A TREE FELLER - A forestry machine includes a frame, and a felling saw carried by the frame. The felling saw includes a saw head. A tree counter associated with the saw head includes an audio sensor providing an output signal representing an audio parameter associated with a cutting action of the saw head. An electrical processing circuit is coupled with and receives the output signal from the audio sensor. The electrical processing circuit determines a tree count associated with the saw head, dependent upon the output signal from the audio sensor. | 04-16-2009 |
20140069554 | INTEGRATED HYDRAULIC SYSTEM FOR HARVESTER - A harvester is provided for felling and processing a tree, the harvester including traction devices and a harvester head. The harvester includes an integrated hydraulic system for operating the traction devices and the harvester head. More particularly, the harvester includes an integrated load sense system for operating the traction devices and the harvester head. | 03-13-2014 |

20130152564 | ELECTRONIC HILL HOLD CONTROL OF A HYDROSTATIC TRANSMISSION - A hill hold control system and method for a closed loop transmission of a machine is disclosed that includes performing the following steps while the transmission is in neutral: sensing motor shaft movement; and generating fluid flow to offset motor shaft movement and cause substantially zero shaft movement. The method can include comparing a brake timer to a delay value, and activating a brake when the timer exceeds the delay value. The method can include sensing when a brake is applied, and discontinuing the step of generating fluid flow to offset motor shaft movement when a brake is applied. Motor shaft movement can be sensed by sensing rotational speed. Generating fluid flow to offset motor shaft movement can include determining direction and magnitude of fluid flow as a function of the sensed movement; and adjusting the direction and magnitude of fluid flow based on recurring readings of the sensed movement. | 06-20-2013 |
