|20130022432||ENGINE COOLING SYSTEM - The present disclosure provides an engine cooling system. The engine cooling system includes a first heat exchanger receiving a first fluid and a second heat exchanger receiving a second fluid. The second heat exchanger is located adjacent the first heat exchanger, thereby creating a stacked heat exchanger. The engine cooling system also includes a third heat exchanger receiving a third fluid. The third heat exchanger is located apart from the stacked heat exchanger. A venturi is located between the stacked heat exchanger and the third heat exchanger. An air mover is mounted to the venturi and located within the venturi. The air mover is configured to move air through the stacked heat exchanger and through the third heat exchanger. In a specific embodiment, the engine cooling system is incorporated into a vehicle, such as a skidder vehicle.||01-24-2013|
|20120312421||HYDRAULIC BUNCHING FINGER - A hydraulic biasing assembly is provided. The hydraulic bunching assembly may include a hydraulic circuit and a hydraulic biasing member configured to provide bias to a bunching finger of a tree felling head. The hydraulic biasing assembly may also include a valve configured to alternately allow hydraulic fluid to transfer from the hydraulic circuit to the hydraulic biasing member and to allow hydraulic fluid to transfer from the hydraulic biasing member to a collector.||12-13-2012|
|20110257842||POWER MANAGEMENT SYSTEM FOR A FORESTRY MACHINE - The disclosure relates to a power management system for a forestry machine. The power management system improves the efficiency of the machine by automating control of the hydraulic systems of the machine. A controller receives a signal from a cutting tool speed sensor and can control the operation of the various pumps and motors on the machine.||10-20-2011|
|20100109380||Wiper control arrangement - An operator's station for a machine having at least two stations comprises a seat mounted to swivel between at least a first position and a second position, at least first and second windshield portions disposed generally opposed or at an angle to one another and generally corresponding to the first and second positions, and at least first and second windshield wipers movably mounted to selectively sweep the first and second windshield portions, respectively. At least one control device selectively renders the first windshield wiper selectively operable when the seat is disposed in the first position and inoperable when the seat is disposed in the second position.||05-06-2010|
|20100104409||System and method for a forwarder headboard - A headboard assembly connected to a machine frame includes a stationary gate that is pivotally connected to the frame and a moveable gate disposed in slidable engagement with the stationary gate. A linear actuator pivotally connects the moveable gate to the frame via first and second pin joints. The linear actuator selectively extends and retracts the moveable gate relative to the stationary gate when the headboard assembly is in an operating position. The linear actuator is further arranged to selectively tilt the headboard assembly relative to the frame when the headboard assembly is in a service position.||04-29-2010|
|20100104406||Stabilizing assembly for a forwarder headboard and method - A machine includes a frame having a payload portion, an operator cab, and a crane disposed on a base connected to the frame between the payload portion and the operator cab. The machine further includes a headboard assembly connected to the frame and disposed between the base and the payload portion. A stabilizing pin arrangement includes a floating connection arrangement connecting the headboard assembly to the frame. The floating connection arrangement includes at least two resilient elements, each of the two resilient elements being disposed on either side of a member connected to the headboard assembly||04-29-2010|
