Re: washer anti freeze in my tires
Are you removing it just to make it ride smoother?
If so, why not just remove about 1/2 of it and leave the rest in. It should help provide traction and it should ride very similar to unfilled tires at 1/2 full.
To do that I would jack the rear of the tractor up and rotate the tire to where the valve stem is at the mid point on the tire. It will drain slow, may take a couple hours, but it will drain.
