I have been into garden tractors for a few years. Wanted to learn about small engines and buying an old sear suburban was cheaper than the class at the local community college. Just got a 1980 C85 (with a johnny bucket on it).
Please Help-- I inherited this work horse from my father in-law after being passed down from his father. I recently brought my wheel horse in for repairs and the service shop said they were unable to find the part; starter/solenoid. I did not want to give up on this beast as even the repair shop said this is a well made machine and is better than anything built today. I eventually found the part but because the shop left the part uninstalled I was unable to see how the starter was wired. Yesterday, I installed the new starter/solenoid but when I connected the battery terminals the tractor wanted to start on its own. I quickly disconnected the terminals and analyzed the electrical schematic map but I am baffled on the proper wiring. I only have a positive (red) battery terminal wire, another red wire, black (ground) wire, and a blue wire with a slot connection. I included pictures of the starter and the electrical schematic map. Any help would be much appreciated!! I l would like to fix this on my own as this seems to be a simple wiring issue. I can add pictures of the tractor itself, but at the moment its under a tarp in a shed at night. Thank you in advance, Matt

I have a few basic electrical system diagrams that are helpful in understanding how the wiring system works. They are not specific to any particular tractor and do not include safety switches. All use the 5 post ignition switches 103-991 for Magneto and 103-990 for Battery Ignition. I failed to include fuses in the Starter Generator drawing, this is an over-site and I would encourage fuses be used as shown in the other two drawings.
Hope this is helpful.
Magneto Ignition system with electric start and solenoid.
Battery powered ignition system with points, condenser, solenoid and electric start.
Battery powered ignition with solenoid, points, condenser, Starter Generator and a mechanical voltage regulator.
We have uncovered a shortcoming in the factory wiring diagrams for S/G battery ignition systems with a four terminal voltage regulator. The wire from the regulator "Gen" terminal to the S/G "A" terminal was omitted. This drawing should clear that up.

Anyone have a wiring diagram for a 655. I found one but I'm not sure if it's correct on the hook ups any help would be appreciated!
Could someone please tell me the size of the front/mid pto belts for the D250? I'm having a heck of a time trying to match one up. Thanks
