Abstract
During monitoring of the driveline of an agricultural implement in respect of overloading and the degree of loading, from a first occurrence of slip, the slip revolutions occurring during a measuring cycle are added up. If the number of slip revolutions exceeds a permissible number of slip revolutions, a signal is generated indicating an overloading condition, a new measuring cycle beginning upon release of the signal to be able to take into account the effects resulting from a change in the behavior of the tractor driver, the nature of the signal being changed responsive to the speed differential between the input speed and output speed of a friction coupling permitting relative rotation. Furthermore, the condition of loading is indicated on the basis of the ratio of the actually measured number of slip revolutions to the number of maximum permissible slip revolutions so that the driver receives a warning prior to a blockage or case of overloading which may lead to overheating or destruction of the coupling serving to protect the implement.
