Ehy everyone. I had a bit of a frustrating morning with my RC72-30B mower deck. It seems I crossed the threads on one of the spindles last time I changed blades. STUPID move on my part. But that to the guys at Sharon Springs Garage in Troy NY I am back mowing again. They had a new blade bolt in stock and were kind enough to let me barrow the correct tap for the spindle. By the way the threads on the spindle are 12mm by 1.25 just for reference. I plan on replacing the spindle shaft this winter but till then I will just be more careful.
