I checked the anti-freeze freeze protection on the Bobcat and the tester only registers 10 degrees Fahrenheit - not nearly good enough for our area. Then I noticed the sticker on the machine that says it contains Propylene Glycol anti-freeze. The usual anti-freeze tester won't work on that, so the protection may or may not be adequate.
One option is to buy a Refractometer tester to test the Propylene Glycol.
Another option might be to drain the system and replace the coolant with Ethylene Glycol antifreeze. If doing this, how does one get all the old coolant out of the system? Are there any drain plugs low down on the Kubota engine block? And where is the drain plug on the rad?
What have others done - changed to Ethylene Glycol or remained with the Propylene Glycol?
Thanks for any help.

Antifreeze for Bobcat S300 - Propylene or Ethylene Glycol?
