摘要： A method and system of operating a machine harvester that presents an improved solution for preventing clogging. There is provided simultaneous measurement of at least a parameter of a base-cutting set, of at least a parameter of a chopping assembly, and of a position of at least a floating roller of a conveyance system. Based on comparisons of the parameters measured and reference values, during a pre-defined time interval, it is possible to manage a propulsion speed of the machine harvester and to manage a rotation speed of cutting disks of the base-cutting set and of billet-cutting blades of the chopping assembly.

摘要： A mower blade speed control system with an electronic control unit providing engine speed commands to an internal combustion engine having a maximum power speed and a reduced economy speed, and a continuously variable transmission with variable displacement providing rotational power from the engine to a plurality of mower blades. The electronic control unit monitors engine load and automatically adjusts engine speed and the displacement of the continuously variable transmission in response to engine load to achieve a constant rotational speed of a plurality of mower blades at different engine speeds.

摘要： A work vehicle for cutting crops includes a header a supported by a chassis of the work vehicle. The header includes a cutter assembly having a cutter bar frame supporting a series of rotary cutters arranged in a lengthwise direction. A gear train, having a first gear and a second gear, is coupled to the series of rotary cutters to transfer power thereto. A cutter control system includes a first motor coupled to the first gear of the gear train and a second motor coupled to the second gear of the gear train. A controller, including a processor and memory architecture, is operably connected to the first motor and the second motor to control operation thereof. The cutter control system drives the first gear at a first speed via the first motor and drives the second gear at a second speed via the second motor. The second speed is different than the first speed to pre-load the gear train into enmeshing engagement with each other in one rotational direction.
