Hey guys, This is in regard to my Toro Proline 32, 1995 model, model #30157. I did a search and didn't find much. Also went to Toro's website and looked at the Master View Parts finder. It has a bunch of diagrams on there but not the one I need. What I need help with: The spindle assembly that holds the blade on. Where can I find a diagram to see how this thing goes together so that when I put it all back, I know it will be on there right. Even more specifically. . .today my father was using it and I here a loud clankclankclank. The whole blade fell off with the whole assembly attached to it out the bottom. Somehow there is a single nut at the top of the assembly (goes around the threads right below the grease zerk) and nothing to stop the nut from backing completely off, which is what happened. Thank God it didn't hurt him. Anyhow, it seems that there would have been some pin or something that would keep that nut from backing off. From looking at it, it looks like the grease had come out and somehow caused the assembly to spin the nut off. . .my guess. Scary, scary. Please help. I can't work without this old mower (no backyards at least). Thanks a million in advance.
