| 20090139194 | AGRICULTURAL HARVESTER SPEED CONTROL - A computer-controlled method of controlling the speed of an agricultural harvester load that is coupled to an agricultural harvester engine by a power transmitting arrangement having various output speeds. The method includes the steps of electronically receiving a desired new load speed from an operator when the engine is operating at an initial engine speed, and electronically driving the power transmitting arrangement through a sequence of the various output speeds until the actual speed of the agricultural harvester load and the actual speed of the agricultural harvester engine are in the same ratio to each other as the desired new load speed and the initial engine speed. | 06-04-2009 |
| 20090235627 | ELECTRONIC ENGINE SPEED CONTROL SYSTEM FOR GRASS MOWING MACHINE - An electronic engine speed control system for a grass mowing machine powered by an internal combustion engine includes a microcontroller providing an output signal to an engine speed actuator for the engine, a pedal position sensor connected to a foot pedal and providing a voltage input signal to the microcontroller based on the position of the foot pedal, a PTO clutch switch providing a signal input to the microcontroller indicating if a PTO clutch is engaged, and a lever position sensor connected to a hand lever and having a range of positions including an Automatic mode position and a plurality of Manual mode positions. The hand lever position sensor provides a voltage input signal to the microcontroller in the Automatic mode position such that the microcontroller output to the engine speed actuator is related to the voltage inputs from the pedal position sensor and PTO clutch switch, and provides a voltage input signal to the microcontroller in a range of Manual mode positions such that the microcontroller output to the engine speed actuator is related to the voltage input from the lever position sensor. | 09-24-2009 |
| 20100293911 | HARVESTER LOAD CONTROL SYSTEM - A method of controlling a multiengine harvester including the steps of operating the harvester in a first mode, operating the harvester in a second mode, and selecting less than all of the power absorbing loads to be driven. In the first mode, the harvester is operated using a first engine and a second engine to drive the plurality of power absorbing loads. In the second mode, the harvester is operated with the second engine being uncoupled from all of the power absorbing loads. In the selecting step, less than all of the power absorbing loads are selected to be driven dependent upon the sensed load on the first engine while operating in the second mode. The first engine is incapable of driving all of the power absorbing loads. | 11-25-2010 |
| 20130167495 | SELF-PROPELLED LAWN MOWER - A self-propelled lawn mower has an on-board battery, an electric blade motor for rotating a grass cutting blade, said blade motor being operationally connected to the battery, an electric drive motor for propelling the lawn mower along a grass surface to be cut, said drive motor being operationally connected to the battery, and a control unit for controlling at least the operation of the electric drive motor and of the blade motor. There is provided a speed monitor for monitoring the speed of the drive motor. This monitor is also connected to the control unit. There is also provided a motion speed selector for selecting a predetermined speed for the drive motor. The motion speed selector is also connected to the control unit. A total energy monitor is provided for monitoring the total energy consumption of the battery. The total energy consumption is the electrical energy consumed by the drive motor plus the electrical energy consumed by the blade motor. The total energy monitor is also operationally connected to the control unit. The user can select a predetermined maximum energy value by means of a maximum energy selector, which is operationally connected to the control unit. The control unit is designed to keep the speed of the lawn mower on the predetermined speed value, independently of the pushing force of the user, and to reduce the total energy as soon as the total energy exceeds the predetermined maximum energy value. The lawn mower affords a comfortable operation for the user, and the battery is protected from overload. | 07-04-2013 |

| 20090188225 | FREQUENCY OF CLIP ADJUSTMENT SYSTEM AND METHOD FOR REEL MOWER CUTTING UNIT - A system and method for adjusting the frequency of clip for a reel mower cutting unit is provided. The system includes an operator interface outputting a voltage corresponding to a frequency of clip setting, and a reel motor controller calculating a travel speed of the reel mower cutting unit based on a voltage reading from a voltage bus and a scale factor applied to the voltage reading, and calculating a required reel speed based on the travel speed, the voltage corresponding to the frequency of clip setting, and at least one numerical constant specific to the reel mower cutting unit. The method includes the steps of reading a voltage on a voltage bus, mapping the voltage to an engine speed, calculating a travel speed of the reel mower cutting unit based on the engine speed and numerical constants specific to the reel mower cutting unit, reading a voltage provided by an operator interface corresponding to a frequency of clip setting selected by an operator on the operator interface, and calculating the required reel speed based on the travel speed, the frequency of clip setting, and numerical constants specific to the reel mower cutting unit. | 07-30-2009 |
| 20100269470 | Optical Yield Monitor for a Sugar Cane Harvester - An optical sugar cane yield monitor that consist of a row of optical sensors mounted in the elevator floor of the harvester in such a way that when combined with the appropriate electronics, software, and connections, the system measures a duty-cycle type reading of billet depth on the slats that is related to the amount of sugar cane flow through the harvester. The sensors are inserted in the elevator floor in such a way that they run in the material flow and self-clean with the normal souring of the elevator floor. | 10-28-2010 |
| 20140144116 | MOWER- CONDITIONER HEADER SPEED CONTROL BASED ON FORWARD TRAVEL SPEED - A self-propelled mower-conditioner includes a rotary cutter bar that feeds cut crop to a driven crop conveying arrangement which delivers the crop to a windrow forming arrangement. The speed at which the crop conveying arrangement delivers crop to the windrow forming arrangement is controlled so as to be a predetermined ratio of the ground speed. | 05-29-2014 |
