I have a 1959 Fordson Dexta that I have been working on for the last couple years. I use it as acreage tractor doing light odd jobs. I has Ca in the rear tires. One tire has more than the other as it is considerably heavier. I experienced this when I took them off to paint. I am considering having the Ca removed and I have heard that I if I do this I should have the tubes replaced. The other choice is to have the lighter tire with Ca topped up and leave them as they are. I don't really see the need to have the Ca in the tires as not doing any real work with the unit but as I am a relative novice, wondering if this might be a mistake with the handling of the tractor with no ballast. As well, can I just drain the Ca Cl2 into a bucket, get as much out as I can then run it that way? Wondering what the experience says.
