Abstract
An interlock mechanism for a tractor transmission having a creeper gear arrangement is disclosed wherein the operation of the tractor engine is halted whenever the creeper arrangement is left in a condition conducive to incurring unwanted creep. The interlock mechanism is in the form of an electrical circuit operably connected to the fuel shutoff valve to halt the flow of fuel to the tractor engine whenever the creeper arrangement is left in a neutral state with the clutch engaged. The interlock mechanism provides electrical power to the fuel shutoff valve under normal operating conditions. Switches associated with the operative components of the transmission control the flow of electrical current through the interlock circuit.
