On the thermostat housing there is a sensor that is connected to a two wire harness that goes to the injection pump; this is the "cold start advance" portion of the system so it starts easier when cold by advancing the timing.
If you disconnect the sensor and it works fine ohm test the sensor, probably shorted.
The sensor on the thermostat housing controls the advance on the injection pump. When it fails it shorts out and blows the fuse. Try unplugging it, replace fuse and see if it starts and runs.

You will want a pan under the tractor to catch the coolant, so as not too have to clean it up.
To comply with the exhaust emissions regulation, the timing of injection pump should be around 6 to 9 degrees before TDC. This timing values do not allow proper start-up operations when engine is cold. To ease engine start-up, a cold advance system gives to the injection pump a temporary over-timing.
