Looking for any information on this machine using the hydra shuttle style transmission. I replaced a voltage regulator yesterday and solved my charging problem.. easy enough machine fires right up and charged good. I let run a few minutes and shut the machine off. I went to restart about 5 minutes later and the starter spins fast almost like no compression, I have not one noise when the tractor was running or when I shut it off. I removed the starter and am able to turn the flywheel over but the cooling fan is not turning?? It is fairly easy to turn with a screw driver... I find it hard since I did not hear any noise that there was some type of internal failure.. but I am at a loss.. I am not sure with the hydra style transmission if something might be wrong there?? Thanks ahead to anyone who can shed light on this machine.
