|20150337954||Forestry Machine Speed Controls - A method for controlling a speed of a machine is disclosed. The machine may have a controller in communication with an operator interface and a hydraulic system configured to control tracks of the machine. The method may include the controller setting a current value for a speed limit on the machine according to a first predetermined value; the controller providing a display on the operator interface indicating the current value of the speed limit, the current value being the first predetermined value; the controller receiving input from the operator interface to change the speed limit to a second value; the controller setting the current value for the speed limit on the machine according to the second value; and the controller changing the display to indicate the current value of the speed limit being the second value.||11-26-2015|
|20150289456||HYDRAULIC ARRANGEMENT FOR A DELIMBER - A knuckleboom loader for processing trees includes a delimber, an actuator, and a hydraulic arrangement. The delimber includes a knife. The actuator is coupled to the knife and is operable to move the knife. The hydraulic arrangement includes a fluid, a tank, a pump, and a valving arrangement. The tank is configured to store the fluid. The pump is in fluid communication with the tank and is configured to supply fluid from the tank to the actuator. The valving arrangement is located between the pump and the actuator. The valving arrangement is operable to regulate a flow of fluid from the pump to the actuator, and from the actuator to the tank for opening and closing the knife relative to a trunk of a tree.||10-15-2015|
|20140338789||TREE DELIMBER WITH INFEED POST - A delimber for performing a delimbing operation is disclosed herein. The delimber includes a cutter head assembly pivotally mounted on a yoke assembly. The yoke assembly is rotatably mounted on a base assembly. The cutter head assembly includes a base portion with a first side and a second side. A box structure is arranged on the first side, whereas a saw assembly is structured and arranged on the second side. The box structure and the saw assembly define a throat region between the two sides. The throat region defines an infeed side and an exit side. At least one curved knife is pivotally supported within the throat region. Further, an elongated post is positioned adjacent the infeed side of the throat region. The infeed post has a first end attached to the box structure, and a second end attached to the base portion.||11-20-2014|
|20140178166||Linkage End Effecter Tracking Mechanism for Slopes - In a work machine having a frame with a lift boom and a stick boom supporting an implement pivotally connected to the opposite end of the stick boom by a pivot pin. A controller determines the position of the pivot pin, detects a motion command signal from an operator control, determines an ending position of the pivot pin based on the motion command signal, and causes the lift boom and stick boom to rotate to orientation angles that will place the pivot pin at the ending position. When operating on a slope, the frame orientation with respect to gravity is determined so that horizontal and vertical motion commands cause the pivot pin and implement to move horizontally and vertically with respect to gravity regardless of the frame orientation. The implement can be maintained at a target orientation as the pivot pin moves by evaluating an orientation angle of the implement.||06-26-2014|
|20130284317||TIMBER PROCESSING WITH A KNUCKLEBOOM LOG LOADER - A machine for processing trees includes a trailer; a loader and a tree processing unit mounted on the trailer. The tree processing unit is configured to independently process loaded trees.||10-31-2013|
|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|
