So my son buys a tractor and drops it off for me to restore after his buddy bought it and then tried to work on it and gave up . He did not want to split the tractor and put a new ring gear on it and in th mean time bought alot of new stuff like clutch disc, pressure plate ,throw out bearing , crank bearing for trans poilot saft, 4 new bolts for flywheel and starter , all the manuals for it and so he told my kid it was a 9N. I started working on it and now I see the engine says 8N on the head and side of block and center main bearibg cap. but the distributor is on the front not the side? its a 3 speed with the overdrive handle on left side ,has brake pedals on both sides , has 9 n wheels , I beam radius bars , only 1 handle for 3 pt lift lever under right side , the steering wheel has 3 bars , fan blade is 6 blades , I can only think someone has upgraded this to a 8N? here is the pictures of the serial number on block and head .? but why is there no side distributor? also the govenor says 9N on it too.
