2. Inability Of The Diesel Motor To Crank

Another problem of  John Deere 5085e is the diesel motor finding it difficult to crank. Engine not cranking can be caused by the current not being enough to energize the motor starter.

At some point, your tractor engine may get overheated, which directly affects the efficiency of work. This is a sign and should be taken seriously. Firstly, an overheated engine shows work overload.

Secondly, it depicts a dirty radiator, loose fan belt, and lack of coolant.

How To Fix

To stop overheating, pour more liquid to refill the coolant. Clean the radiator thoroughly to let go of the specks of dirt. In addition, reduce the load, or you can also shift the gear lower. Above all, adjust the tension of the fan belt.
