The signs of a failing starter motor in agricultural equipment primarily include a clicking noise, slow cranking, or no response when the ignition is engaged. These symptoms indicate that the starter motor is not functioning properly. A clicking noise often occurs when the battery voltage is insufficient to engage the motor fully, which can also lead to slow cranking if the starter does manage to turn the engine over but does so at a reduced speed. If there is no response at all, it may point to a complete failure of the starter motor or issues with the electrical connections, battery, or ignition switch. The other choices do not specifically relate to starter motor issues. Excessive engine noise could be indicative of various engine problems but is not a direct sign of starter failure. Fuel leakage typically suggests problems with fuel lines or injectors rather than the starter motor itself. Increased emissions are more likely related to fuel combustion issues within the engine rather than any problems originating from the starter motor. Thus, focusing on the defined symptoms provides a clearer understanding of starter motor failures.
