Hi All. I took the front rims off to get new tires and tubes installed and the bolts weren't right on the right side so I looked in the newest parts book I have and noticed the rims don't look like the pictures. The serial number on the tractor is 134666. I know the front could have been changed out in the past but neither of the pictures match the configuration of this rim. Sooo.. is this rim a after market or maybe a newer style than what my book goes to (TC-28 "H" edition ) which I believe was printed in or near 1960. I also have the "F" edition printed in or near 1952 but it shows the same pictures. This looks like it could be a heavy duty version to hold the weight of a picker or cultivator? I have picker/cultivator hubs on it (the ones with the little nubs that stick through the cover). I couldn't find any info in the parts book on a heavy version except there is a listing with no pictures in the attachments section for a lower bolster to equip cotton picker tractors with dual front wheels.(?) It doesn't bother me but I would like to know what I've got to make getting parts easier. Thanks ! ...Randy
