Roland,
Thanks for your interest in helping me. The time line for my problem began when I started preparing the tractor for this season. After finishing the normal services to bring it out of hibernation I tried to start it. The engine would crank, but not start. After a few attempts I got nothing. I then tried jumping the solenoid to determine if was faulty or if the starter was bad. It cranked a couple of times but did not start. After that everything was dead. I did the service manual checks and determined both the starter & solenoid were bad. I ordered the parts and installed them and attempted to start the tractor. When I turned the key to "run" I heard a "clunk" (kind of metal to metal) sound and immediately turned the key to off after only one attempt. When I investigated I could see that the drive pinion on the starter could not engage the flywheel because it would not move. As I mentioned, I have tried all the testing methods offered in the CC & Kohler service manuals looking for a reason for the lock up. By the way, the oil level is normal. I have just about come to the conclusion that the engine has seized and either needs to be rebuilt or I need a new CC. Any insight you can provide would be helpful. Thank you.
