Re: How about the reverse?
Why? But anyway, park with the valve stems on the bottom and either jack the machine up and drain into a bucket or put the adapter on, hook up a pump in the opposite direction and pump it out. You could also do it without a pump by pumping up the tire with air and then changing over to the hose adapter. The air pressure will push the fluid out. You will have to pump up the tire several times to get out all of the fluid.
PS What type of fluid is in your tires?
Have fun LOL
