  • Patent number: 4856612
    Abstract: A method of controlling the operation of a loader to encourage the use of an operator restraint mechanism is disclosed wherein a first signal is generated by a seat sensor to indicate the presence of the operator in the operator seat and a second signal is generated by a sensor in the operator restraint mechanism to indicate use of the mechanism. The hydraulic system will not be enabled unless the second signal is generated immediately subsequent to the generation of the first signal. Unless the first and second signals are generated in the proper sequence, the starting of the engine will also be disabled. The generation of first and second inverse signals, indicating the lack of the presence of the operator in the seat and the disengagement of the operator restraint mechanism, respectively, will disable the loader hydraulic system.
