A movable machine including a chassis, a tool coupled to the chassis, an operator control carried by the chassis and a controller. The controller is communicatively coupled to the operator control. The controller being configured to send a force feedback and/or a vibration feedback to the operator control thereby conveying information to the operator. The information is not related to a load encountered by the tool.

Active force/vibration feedback control method and apparatus for a movable machine

A method for detecting parasitic power circulation within a work vehicle may include controlling an operation of the work vehicle such that a transmission of the work vehicle has a first output speed and determining a first power value associated with power transmitted through a drive shaft of the work vehicle at the first output speed. The method may also include adjusting the operation of the work vehicle such that the transmission has a second output speed that differs from the first output speed and determining a second power value associated with power transmitted through the drive shaft at the second output speed. In addition, the method may include comparing the first and second power values to a predetermined relationship to determine whether the work vehicle is currently experiencing parasitic power circulation, wherein the predetermined relationship is associated with operation of the work vehicle without parasitic power circulation.

System and method for detecting parastic power circulation within a work vehicle

The present disclosure is directed to a control method for controlling the operation of a lift assembly of a work vehicle, wherein the lift assembly includes an implement and at least one loader arm coupled to the implement. As such, the method may generally include transmitting at least one first command signal in order to simultaneously move the loader arm and the implement towards a return position. The first command signal(s) are associated with moving the loader arms at a movement velocity. The method also includes monitoring a height of the implement relative to a driving surface of the work vehicle during simultaneous movement of the loader arm and the implement. As such, the method may also include reducing the movement velocity of the loader arm when the height is below a predetermined threshold.

Work vehicle with improved loader/implement return position control

The present disclosure is directed to a work vehicle such as a loader having a bucket attached to the lift arms of a lift assembly and including a system and method for controlling the operation of the lift assembly so as to enable the loader to move over varying terrain without spilling the contents of the bucket. The system includes a chassis sensor, a bucket sensor, a gravity sensor, and a control system for varying the position of the bucket. The system adjusts the bucket's orientation via the control system to maintain a 90 degree difference between the bucket vector and the gravity vector.

Anti-spill for loaders

A fluid heating system for a work vehicle includes a pressurized fluid circuit having a pump for providing pressurized fluid to the fluid circuit. A control module for controlling a first control device is in fluid communication with the fluid circuit, the first control device operable between a first position and a second position. The first position of the first control device permits a load sense pressure to be applied through the first control device, thereby preventing pressurized fluid from the pump flowing to a pressure return tank for heating the pressurized fluid. The second position of the first control device prevents the load sense pressure from being applied through the first control device, thereby permitting pressurized fluid from the pump flowing to a pressure return tank and resulting in heating of pressurized fluid of the fluid circuit.
