When my 743 has been running in the summer heat for more than 30 minutes the temp gauge goes to about 3/4 towards hot. I have a full reservoir of fluid and the rediator is also full. Does this sound like a thermostat problem or is this normal nothing to worry about?

Replace the thermostat, you don't want to risk getting it hot, kubota's love cracking heads when they get too hot. Thermostats are pretty cheap.
If that doesn't fix it, it could be a blocked radiator. If it was me, i would replace the thermostat then flush the cooling system with a good quality engine flush then replace the coolant.
Check your radiator fins, they may be cloged up with junk.

Thanks Tazza. I thought that would be your answer but I wanted to get anothr opinion to be sure. Do you know if I can get the thermostat at any Kubota dealer or do I need to go to Bobcat direct?

Any kubota dealer.
I got mine from the local importer of non-genuine Kubota parts, 1/2 the price of genuine bobcat. But even from bobcat, the price was still reasonable.
Get your self some high temperature silicone, that way you don't need to buy a new gasket for when you replace the thermostat. I love my silicone sealant i use it for everything :)
Any problems just yell

Another thing to also check for is make sure there is no water coming out of the weap hole on the water pump, and your water pump maybe a little worn out also
