Temperature sensor’s Mahindra 3015

[Bobesmo]

I recently bought an older Mahindra 3015 HST. I have not been able to find the exact year manufactured but believe it is 2004-2008.
I am trying to figure out what the two sensors are below the thermostat. From the parts schematics I have found online, one is a thermo switch and the other is gauge temp. Why are there 2 sensors? I know the lower one(gauge temp) sends to temperature gauge on the instrument panel, but what does the switch do?
Thanks for any help!

I don't have a Mahindra but here's a guess.
The switch may be there to recognize overheating and shut the tractor down.

Thanks for the reply bczoom, I hadn’t considered that possibility.
