Another couple possibles.

Charging system has failed or electric PTO clutch partially shorted over taxing charging system. Either one will severely drain a new battery during operations.
Voltage regulator bad possibly?

You can test the stator. Set the VOA meter on AC volts and remove the connector from the regulator. With the engine running at 3600 rpms probe the two white wire that come out of the stator. You should read over 28 volts. If not the stator is bad if over 28 volts the regulator is bad.

I don't know where to find the stator or the regulator. Is the regulator a silver cylinder on the left side of the engine that the positive battery cable attaches too?

No it is on the side opposite dip stick. It is the rectangular box held on by two screws one on each end. It has a straight three prong connector plugged on it with two white wires one on each end and a purple one in the middle. These white wires are the ones you probe with the VOA meter set to AC volts after you unplug it from the regulator. You should read over 28 volts. If not the stator is bad if over 28 volts the regulator is bad.

33.5 on the white wires

What are you getting at the purple wire dc volts? Check the voltage at the purple wire not running switch on you should get battery voltage. If not you have a wiring problem.

Are you saying check the dc volts at the purple wire when the engine is not running, and the key switch is in the on position?

Yes. To make sure you have battery voltage so if charging system is charging it has a path to get to the battery to charge it.

Is this the voltage regulator? It feels like it is just a hunk of metal. How can that go bad?

In side that "hunk of metal" are electrical parts surrounded by resin
They burn out, short circuit or open circuit
