My u17 mini excavator runs great for 30 to 45 minutes then gradually starts getting hot. Eventually it gets really hot and if I run it too long the small water filler tank is boiling when I turn off the machine. The machine runs great and seems to have good power. Also, there is no discoloration in the exhaust

Gary,

not being an A$$ but lets start with the company - KuBOTA ...........only ONE "A"

Getting to the heat - have you cleaned the radiator REALLY REALLY well???

Once you get to the blown head gasket and the exhaust color change - it will be WAY too late.

boiling water in the reserve tank is a sign of bad things to happen soon.

GET a good air compressor = blow out the radiator well, then do it again, start from fan side out.

hopefully it has 'coolant' and NOT 'water' in the rad !
50/50 antifrezze /water.

as SOON as the heat goes up SHUT IT OFF !

maybe a loose fan belt ?
