A cane harvester including a support member and a basecutter assembly carried by the support member. The basecutter assembly includes a plurality of basecutter units and a control system. The plurality of basecutter units include first and second basecutter units. The first basecutter unit has a first set of blades and the second basecutter has a second set of blades. The first set of blades are rotatable by the first basecutter unit, and the second set of blades are rotatable by the second basecutter unit. The control system is configured to synchronize the first set of blades with the second set of blades.

A brush cutter includes a center deck that is pivotally coupled to a first wing deck and a second wing deck. Each deck has a hydraulic cutting assembly. A mounting portion can be attached to a front carrier portion of a drive vehicle. The brush cutter has a hydraulic manifold operably coupled to each cutting assembly and configured to be operably coupled to a hydraulic system of the drive vehicle. The manifold includes valves that control the flow of drive fluid to the hydraulic cutting assemblies. Sensing arrangements signal the valves to shut off the drive fluid to the wing decks if the wing decks pivot upward from a lowered position to a first angular position. The sensing arrangements can optionally signal the drive vehicle's hydraulic system to reduce the flow of drive fluid to the hydraulic manifold for each wing deck that pivots upward to the angular position.

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.

A vehicle includes a pump having a swash plate tiltable about a swashplate tilt axis, wherein rotation of the swashplate changes the title angle and effects a change in volumetric displacement of the pump. A controller is operatively coupled to the swashplate to effect rotation of the swashplate, the controller including a processor and memory, and logic stored in the memory and executable by the processor, the logic configured to automatically control at least one vehicle characteristic independent of a user input command.

A mounted mower coupled to a hitch of a work machine that has an output, the mounted mower comprising a sub-frame having one or more hitch couplers selectively coupled to the hitch of the work machine. The mounted mower also has a mower arm with a first end and a second end, the first end being pivotally coupled to the sub-frame. The mower aim is pivotable about the first end between a first position and a second position relative to the sub-frame. The mower arm has a mower head mechanically coupled to the mower arm at the second end. The mower head has at least one disc pivotally coupled to the mower head, the at least one disc able to rotate about a disc pivot axis defined by the respective disc. Further, at least one disc may change the direction the disc rotates between the first and second position.

A basecutter assembly for a sugarcane harvester includes a cutting spindle powered by a first power source, and a transport spindle powered by a second power source independent of the cutting spindle. A torque sensor is coupled to the cutting spindle. A harvester controller defines a target cutting torque value for the cutting spindle based on a desired crop cut height and determines a current cutting torque of the cutting spindle while cutting the crop. The harvester controller may then control a height of the cutting spindle relative to a ground surface to maintain the current cutting torque substantially equal to the target cutting torque value to achieve the desired crop cut height.

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.
