If you have a 2720 or Gen 1 2032R and need to drain the coolant from the radiator you'll find that it can get a little messy. The petcock at the bottom of the radiator is right over the top of the front axle. If you prefer to keep things a bit cleaner when working, attach a length of 5/16" clear plastic tubing to the petcock outlet at the bottom and run that tubing in to a bucket. When you open the petcock everything runs through the tube. No mess, no spills. The 5/16" tubing holds tightly enough that it will stay in place on it's own.
