Somewhere in the back of my mind I remember reading that you have to be careful buying starter/generators on ebay because some starter/generators(Cub Cadet?) turn backwards from what the ones for Wheel Horse do. Why? Are they mounted differently? Do the engines run backwards? Did Kohler ever make one that did?
'60's Jacobsen Chief 800's (8HP Kohler) had the starter/generator mounted so they were driven from the PTO side. This necessitated opposite rotation. The Chief 1000 and 1200 (Kohler 10 and 12HP) were driven from the flywheel side and use more common rotation. The tractor was pretty narrow and this allowed the starter to all fit inside the grill shell. When they began the 10 and 12HP they said forget the aesthetics and hung the pulley for the starter/gen outside the grill shell.
Speaking of Jacobsens and reverse transmissions...
These same Chief tractors used a very common cast iron Peerless transaxle. Rev + 3 fwd and a creeper gear. I think the entire assembly was common to early JD (perhaps less the creeper) and other makes. Only problem was, Jacobsen put the engine in backward! The PTO is on the left side. Naturally, the transaxle would run as the original poster states. They "cured" this with a little bitty round gear box added onto the input shaft. It reversed the rotation prior to entry into trans. It consisted of two spur gears...even number of gears opposite rotation. It works, but is mighty strange!
Here's a crazy thought for reversing rotation (if the original problem does exist: Flip the trans axle end for end! Rotation will be reversed...might need a wacky shifter!
Always a wise cracker, eh? :fing32:
