Attorney, Agent or FirmInternational ClassA01D 075/18AbstractAn agricultural vehicle, tractor, or combine includes a slip monitoring system for determining whether a slip condition exists. The agricultural vehicle includes a combustion engine which indirectly drives a piece of equipment such as a rotor. The rotor is mechanically coupled to the engine via a rotor-drive belt system including two belts and four pulleys. The slip monitoring system analyzes the speed of the rotor and the speed of the engine to determine if there is slippage between the belts and the pulleys. The system determines when a slip condition exists by comparing the ratio of the rotor speed to the engine speed to the ratio of the rotor speed to the engine speed under no-load conditions. When the system determines that the ratio is below the threshold, a display provides visual and audio warnings of the slip condition. The monitoring system is implemented as a software subroutine. | |
